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

or Harman Pro System Architect and

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 Sec­tion 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

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™ com­patible amplifier.* The module connects the amplifier to a 100 Mb Ethernet network allow­ing 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
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 con­nected 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 inher­ent 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 fea­tures 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 process­ing. Audio routing, faders, meters, polarity & mute, input compressors, filters, multimode
output limiters, error reporting, and load monitoring are all available. A built in noise gen­erator 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-band­width audio distribution, control, and monitoring.

*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.)

3 Installation

Before beginning, please carefully note:

CAUTION: STATIC ELECTRICITY MAY DAMAGE THE UNIT. Use caution when han­dling the unit. Carefully ground yourself BEFORE touching the unit. Avoided unnecessary
touching the components or solder pads on the circuit board. It is best to handle the unit by
its front panel only.

3.1 Prepare the PIP

The PIP comes ready to install in the amplifier. This unit does not require setting the “IQ
address” as the older current loop, Crown bus, units did. Each PIP (as well as all network
components) comes preprogrammed with a unique network (MAC) address. The IQ or HiQ­net address is then set (automatically or manually) via the IQwic or SystemArchitect control
software. (Also you will set a TCP/IP network address.)

3.2 Prepare the Amplifier

Turn down the amplifier level controls (full counterclockwise) and turn off the
amplifier.

Disconnect the amplifier's power cord.

Remove the existing PIP module from the amplifier back panel (two screws). This may
involve disconnecting the PIP module from a PIP2 input adapter. If a PIP2 input adapter is
present, remove ribbon cables from the adapter.

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

3. Set amplifier sensitivity.

3.4 Install the Wiring

IMPORTANT: Please read the wiring rules below before installing the wiring. If your com­puter 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 con­nect 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 connec­tor 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 con­nect 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 How to Set Up TCP/IP

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 NET­WORK 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.

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-net­work 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 net­work 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 com­ponents, 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.
