Quick Install Procedure

This procedure is provided for those who would like to install the PIP card in the shortest time

possible and are already familiar with Crown’s IQ System

® or Harman Pro System Architect and

HiQnet or TCP/IQ. Less experienced installers or those wishing a full explanation of the installa-

tion procedure are encouraged to go to Section 3 where the full installation procedure is

described.

Prepare the amplifier:

1. Turn down the level controls of the amplifier and turn off the amplifier.

2. Unplug the power cord from the AC mains.

3. Remove the existing PIP or cover from the amplifier back panel (two screws).

Install the PIP module into the amplifier:

4. Carefully ground yourself to the chassis of the amplifier before installing the PIP card. It is a

good idea to maintain ground contact between yourself and the amplifier while inserting the

module into the amplifier in the next step.

5. Turn the PIP upside down so the ribbon cable connectors located along the back edge on the

underside of the module can be clearly seen (See Figure 3.1). Attach the ribbon cables from

the amplifier to the ribbon-cable connectors. The 20 pin cable (A) should connect to the con-

nector closest to the corner and the 18 pin cable (B) should connect to the other connector.

Important: Be careful when attaching the ribbon cable to the connector. Applying pressure to an

improperly seated connector could cause the keying tabs, which ensure proper pin alignment, to

break. Connecting the ribbon cables with improper pin alignment will likely result in damage to

the PIP.

6. With both cables firmly attached, turn the PIP back to an upright position. Verify that the

cables run untwisted between the amplifier and the PIP. Insert the PIP into the amplifier while

taking care not to crimp, pinch or stretch the ribbon cables.

7. Tighten the two PIP mounting screws until it is secured to the amplifier back panel, making

sure the supplied star-washers contact the PIP panel for a good ground connection.

Install the wiring:

8. Connect the PIP to the Ethernet network used for control. Each PIP must connect to its own

port on a 100 Megabit Ethernet Switch with a standard straight CAT5 network cable. (See Sec-

tion 3.4 if more information is needed.) A 10 Megabit connection will work with the PIP-Lite

and PIP-USP3 but is not recommended for systems with a high number of components. A 10

Megabit connection will not work with the PIP-USP3/CN.

9. Connect the audio signal wiring to the PIP. (See Section 5.1 for more information.)

10. Connect the amplifier back to the AC mains and reset the back panel input attenuators to the

proper levels.

Networked PIP Series

*A PIP2-compatible amplifier is necessary to use these PIP modules. To determine if the amplifier is

PIP2 compatible, look for the logo on the back of the amplifier. These PIPs are NOT compatible

with older Crown PIP amplifiers (except the PIP-Lite if a USP2 adapter is first installed in the amplifier.

See Section 9 for more detail on the USP2 adapter.)

1Note that the PIP-Lite and PIP-USP3 cannot receive or transmit CobraNet audio. Please use the PIP-

USP3/CN if this function is desire

1 Welcome

The Crown

® Networked PIP™ series includes the PIP-Lite, PIP-USP3, and

PIP-USP3/CN. Each PIP (Programmable Input Processor) is a module for a PIP2™ com-

patible amplifier.* The module connects the amplifier to a 100 Mb Ethernet network allow-

ing it to be remotely controlled and monitored via System Architect or IQwic software.

Each PIP is a network component and connects to the audio control/monitor network using

standard 100Mb Ethernet hardware. This provides faster communications with HiQnet or

TCP/IQ than the previous current loop, IQ

® bus, connectivity method. With this protocol, a

large (or small) system can be interconnected using standard off-the shelf 100 Mb Ethernet

components (switches, Network Interface Cards, and cables). All the PIPs can also be con-

nected to the same network used to pass CobraNet audio.

The audio path in the PIP-Lite is processed totally in the analog domain without the inher-

ent noise induced by analog-to-digital conversions. While DSP-type functions are not

included with this type of architecture, the standard SmartAmp™ features are. These fea-

tures include level control, input compressors, multimode output limiters, error reporting

and load monitoring. The enhanced AUX port capability allows the user to interface with

the amplifier to provide external manual control and monitoring.

The Crown PIP-USP3 and PIP-USP3/CN include the same SmartAmp features as the

PIP-Lite. In addition, the USP3 and USP3/CN are 3rd generation DSP-based PIPs.

Their SHARC DSP processor gives the user an enormous amount of digital signal process-

ing. Audio routing, faders, meters, polarity & mute, input compressors, filters, multimode

output limiters, error reporting, and load monitoring are all available. A built in noise gen-

erator and sine-wave generator provide noise masking and test capabilities. In addition, the

PIP-USP3/CN allows the transport of real-time digital audio via CobraNet™ over the same

100Mb Ethernet network, providing a simple to install, single-plug solution for full-band-

width audio distribution, control, and monitoring.

3.3 Install the PIP Into the Amplifier

Carefully ground yourself to the chassis of

the amplifier before installing the PIP. It is a good

idea to maintain ground contact between yourself

and the amplifier while inserting the module into

the amplifier.

Connect the PIP module to the amplifier.

1. Turn the PIP module upside down so the ribbon

cable connectors located along the back edge on

the underside of the module can be clearly seen

(See Figure 3.1)

2. Attach the ribbon cables from the amplifier to the

ribbon-cable connectors. The 20-pin cable (A)

should connect to the connector closest to the

corner and the 18 pin cable (B) should connect

to the other connector.

Important: Be careful when attaching the ribbon

cable to the connector. Don’t pull

cables out if they are short. Applying

pressure to an improperly seated

connector could cause the keying tabs, which

ensure proper pin alignment, to break. Connect-

ing the ribbon cables with improper pin align-

ment will likely result in damage to the PIP

module.

3. Set amplifier sensitivity.

Mount the PIP module in the amplifier.

1. With both cables firmly attached, turn the PIP

back to an upright position. Verify that the cables

run untwisted between the amplifier and the PIP

module.

2. Insert the PIP module into the amplifier while

taking care not to crimp, pinch or stretch the rib-

bon cables.

3. Fasten the PIP module to the amplifier rear panel

with the two supplied mounting screws. Be sure

to use the supplied star-washers for a good

ground connection.

3.4 Install the Wiring

IMPORTANT: Please read the wiring rules below before installing the wiring. If your com-

puter does not communicate with the network devices after installation and addressing,

re-read this section, as well as Section 4.2 on addressing rules.

3.4.1 Wiring Rules

• Connect each device to the network through its own cable in a Star Network. Do not con-

nect them in a serial fashion (as was done with the previous IQ current loop method).

• Make sure each device has its own Category 5 certified cable connecting it to a central

concentrator, most often a switch.

Detailed instructions follow on the next page.

3.4.2 Wiring Instructions

1. PIP-Lite and PIP-USP3 ONLY: Using a standard CAT5 cable, connect the network con-

nector to a 100 Mb port on an Ethenet switch that is used to form the control network. For

more detail see Section 6.2, Network Basics. If the PIP module is not to be connected to a

control network, it can be temporaily connected to a computer’s Ethernet port with a crossover

cable (TX and RX pairs switched) to set up the PIP module for desired operation.

PIP-USP3/CN ONLY: Using a standard CAT5 cable, connect the Primary CobraNet connec-

tor to a 100Mb port on the Ethernet switch that is used to form the CobraNet network. For

more detail, see Section 4.1.3. We highly recommend that the CobraNet be a standalone or

separate-network LAN. If network redundancy is required, use a standard CAT5 cable to con-

nect the Secondary CobraNet connector to a 100Mb port on the auxiliary CobraNet network.

HiQnet and TCP/IQ control is also available over the CobraNet network using Harman Pro

System Architect or IQWic software.

2. Connect the Audio Input Wiring. The PIP module is equipped with removable barrier block

connectors for each channel’s input. See Section 5.1 for more detail on audio wiring. The

USP3/CN allows the use of standard balanced audio inputs to act either as CobraNet

backup, an emergency override of CobraNet audio, or as an audio input to the CobraNet

network. See Section 5.1.6 for additional details. The single 5-pin removable barrier block

connector allows both audio channels to be inserted into the USP3/CN, then routed via

software control.

3. Connect the AUX wiring if used. See Section 7.1 for more information.

4. Reconnect the amplifier's power cord.

4.1 Introduction

Before you set up a TCP/IP network with addressing, it’s important to understand all the

terms involved. The following glossary explains network terminology.

4.1.1 Glossary

Network: A group of interconnected components, such as a central computer, network

switching equipment, and other computers or devices.

TCP/IP network: A network made of a computer, network switching equipment, and other

network devices such as network PIP cards plugged into power amps that communicate

using TCP and IP protocols.

Subnet: A small network within a larger network. For example, a control network might be

a subnet of a venue's network, which could include computers throughout the building. Or

an audio network might be divided into subnets. For example, one audio subnet might be

for the house system and another audio subnet might be for the paging system.

IP address: An identifier for a computer or device on a TCP/IP network. Each device in a

network has its own IP address to identify it. Example: 126.126.17.42. Networks using the

TCP/IP protocol route messages based on the IP address of the destination. An IP address

is made of four numbers separated by periods. Each number can be zero to 255. Typically

the last number should never be a zero or 255. For example, 126.126.17.1 could be an IP

address. 126.126.17.0 would not be a typical IP address.

A TCP/ IP or IP address has two parts: the NETWORK ID and the HOST ID. The NETWORK

ID identifies the network, and the HOST ID identifies either the subnet and device, or just

the device if there is no subnet.

The subnet mask is a code that indicates which part of the TCP/IP address is the NET-

WORK ID and which part is the HOST ID. In subnet-mask code, 255 means "This part of the

address is the NETWORK ID".

Example:

Suppose the IP ADDRESS of a device is 126.126.17.42

and the SUBNET MASK is 255.255.0.0.

That means, (126.126) is the NETWORK ID. The remaining set of numbers (17.42) is the

HOST ID.

4 How to Set Up TCP/IP

136763-7_4-08_networked_pip-series_reference_manual.fm Page 19 Monday, March 17, 2008 11:17 AM

Networked PIP Series

page 20 Reference Manual

If your audio network stands alone (it is not part of a larger network ) then the HOST ID

identifies each device in the network.

If your audio network is part of a venue's larger network, your network is actually a sub-net-

work or subnet. In this case, the HOST ID can be further divided into two or more parts. The

first part is the SUBNET ID. The other part is the DEVICE ID. The first part of the HOST ID

identifies the subnet of your audio system, and the remaining part identifies the particular

device within that subnet.

So in this case, a complete IP address is in the form

NETWORK ID - SUBNET ID - DEVICE ID.

All devices in the network have the same network ID. All devices in a subnet have the same

subnet ID.

There are many resources available on the Internet for IP and subnet calculation. For a

stand-alone system, Crown has provided a worksheet of a tested configuration later in this

section.

DHCP (Dynamic Host Configuration Protocol): This a protocol for automatically

assigning IP addresses to devices on a network. With dynamic (DHCP) addressing, a

device might have a different IP address every time it connects to the network. If a computer

is NOT connected to a network with a DHCP server, the computer will place a default net-

work ID into the TCP/IP address and Subnet Masks.

DHCP is available with Firmware version 2.0 or higher. It requires Harman Pro System

Architect to configure.

4.2 TCP/IP Addressing Rules

In the next section, you will be assigning static TCP/IP addresses to the devices in your

network. When you do so, be sure to follow the addressing rules below. Otherwise, the

computer may not communicate with the devices.

1. Turn off DHCP (automatic addressing).

2. Assign each device a static (fixed) IP address. An IP address is made of four numbers

separated by periods. Each number can be zero to 255.

3. Make sure that the computer and all the devices have the same NETWORK IDs in their

addresses. This tells the computer that all those devices are on the same network. Various

tools are available to determine whether devices are on the same network. In the addressing

utility described later, if items are NOT on the same network, they are highlighted in the list.

4. Make sure that each component has its own TCP/IP address, and there are no duplicate

addresses. The same holds true for IQ addresses.

5. Assign a subnet mask. Make it the same for all devices on the network. If the network you

are assembling will interconnect with other networks, your network is considered to be a

subnet within the larger network. Check with the network administrator to determine the

proper Subnet Mask for your subnet.

If you have a stand-alone network, you may use a Subnet Mask of 255.255.0.0 for all com-

ponents, including the computer.

Note: Just because two components have the same subnet mask does not mean that they

are on the same network. As we said, the subnet mask just tells what part of the TCP/IP

address is the Network ID.

4.3 Network Setup Wizard

The network setup wizard can assist you in setting up your network for the first time. Using

the wizard, you can address your components and be informed of addressing and other

errors in the system. Please note that this wizard is designed to work with devices that are

on the same physical network segment as the computer it is running on. It will not work

through a router.

Select Network Card

The first page of the wizard lists all the network adapters (cards) currently in the computer.

If you have more than one adapter, you can scroll through the list and see the IP Address,

Subnet Mask and Gateway address assigned to each card.

If you have a card with an IP address of 0.0.0.0, it typically means one of several things:

1. The card is disabled.

2. The card is not connected to a network.

3. The card is setup to obtain it's address from a DHCP server, and no DHCP server is

available.

Select the card that is connected to the system and click the Next button.

Discover Devices on the Network

This page scans the network for available network devices and lists them by product.

If you believe you are connected to the network, but no devices are showing up:

1. You may have selected the wrong network adapter. Click Back and select the proper net-

work card.

2. You may have firewall (e.g. Checkpoint, Zone Alarm, Windows XP Service Pack 2) or

proxy software running on the computer that is interfering with network communications.

Turn off the firewall or proxy and restart the IQ software.

3. Your network may be improperly configured, or components may not be physically con-

nected to the network or powered on. Check your network configuration, then click the

Refresh button.

If some, but not all, network components are displayed in the list, check to make sure the

missing devices are physically connected to the network and powered on, and click

Refresh. (If the device is connected and on, you may need to power cycle the device.)

When you are satisfied with the list of devices, click Next.

Address Devices on the Network

The box labeled Check for Errors will report to you if any devices in the system have mis-

configured IP addresses, or if there are duplicate IQ or HiQnet addresses in the system. If

there are, what happens next is dependent on what Action to Take is selected:

Readdress all devices - this selection will be the default if 10 or more addressing errors

are found in the system. This selection will bring up another page in the wizard where you

can readdress all the devices in the system.

Fix errors individually - this selection will be the default if 1 to 9 addressing errors are

found in the system. This selection will bring up another page in the wizard where the errors

will be listed and you will have the opportunity to fix each error individually.

No action at this time - this selection will be the default if no addressing errors are

found.

Select an Action to Take and click Next.

Readdress All Components

This page gives you the opportunity to assign IP and, optionally, IQ addresses to all devices

in the system. The default values will Assign IP addresses (including and Subnet Mask

Gateway address) that match the addresses assigned to the selected network

adapter in the computer. You can also Assign IQ Addresses by checking the appropriate

box and assigning a range of addresses.

The wizard is able to avoid assigning IP addresses used by other Crown or Harman compo-

nents, but it cannot detect if it has assigned an address that is currently being used by

another computer or TCP/IP device on the network. If you have other computers or devices

on the network, be sure to assign a range of addresses that does not conflict with the

addresses assigned to these network nodes.

Click the Readdress button to initiate the readdress process. The wizard will assign

addresses to, and reboot, each device on the network.

When the readdressing process is finished, click the Back button to check again for errors,

or the Finish button when you are ready to close the wizard.

Fix Errors Individually

This page gives you a list of each error detected in the system. Select the error you want to

fix in the list, then click Fix Error. A dialog will be displayed that will give the opportunity to

change the addresses of the offending device. Clicking OK on this dialog will change the

address on the selected device, reboot that device, and remove the error from the list.

When you are done fixing errors, click the Back button to check again for errors, or the

Finish button when you are ready to close the wizard.

5 Operation

The PIP-Lite, PIP-USP3 and PIP-USP3/CN are network components that allow control and

monitoring of the power amplifier over a standard 100 Mb Ethernet network. Connection to

the control computer is made through its standard network adapter.

The PIPs can function independently from the network control. Once the processing is con-

figured, the module's non-volatile memory allows the amplifier to continue to function with

no external control.

The USP3/CN provides a single-click solution for distribution of audio, control, and moni-

toring of the amplifier. A single CAT5 connection to a standard Fast Ethernet network used

for CobraNet control provides all of the necessary infrastructure wiring. The software can set

up CobraNet audio routing and addressing. In the unlikely event of a network failure, the

analog audio balanced inputs provide a backup audio path that can be automatically

selected by the USP3/CN if CobraNet audio is disrupted.

Crown strongly recommends the use of a 100 Mb Ethernet network for control and monitor-

ing. While some Crown products will function on a 10 Mb Ethernet network, their perfor-

mance and network expansion capability will be limited.

Figure 5.1 shows the system block diagram of the PIP Lite.
