CP2 & CP2E Troubleshooting (Continued)

TROUBLE POSSIBLE CAUSE(S) CORRECTIVE ACTION

IRP2 or serial port not

placed properly.

Verify placement of IRP2

(hold phosphor card under

IRP2 while pressing button)

and tighten serial cables.

Used wrong IR/serial

port.

Verify that proper IR or serial

port is defined.

A/V system device

does not respond.

Serial cable not wired

correctly.

Verify that serial cable is

wired correctly for RS-232,

422 or 485.

Device is not receiving

sufficient power.

User the Crestron Power

Calculator to help calculate

how much power is needed

for the system.

NOTE: If communication cannot be established or the control system is locked-up,

refer to “Troubleshooting Communications” in the Crestron 2-Series Control System

Reference Guide (Doc. 6256).

NOTE: Passthrough Mode enables Viewport access to any serial controlled device

on the network. This aids in troubleshooting by allowing direct communication

between the PC and a network device (effectively “passing through” the CP2 or

CP2E). For information pertaining to Passthrough Mode, refer to “Passthrough

Mode” in the Crestron 2-Series Control System Reference Guide (Doc. 6256)

Network Analyzer

To assist with troubleshooting, the unit contains Crestron’s patent-pending network

analyzer to continuously monitor the integrity of the Cresnet network for wiring

faults and marginal system performance or other network errors. For more

information on how to use the network analyzer, refer to the Crestron Toolbox help

file and use the index to search for “Network Analyzer”.

Battery Replacement

A Lithium battery is used to power the system clock within the CP2 & CP2E. Under

normal conditions, it will last for approximately 10 years. In the event that the clock

fails, only an authorized technician should replace it. Refer to caution statement

below.

CAUTION: Danger of explosion if battery is incorrectly replaced.

Replace only with the same or equivalent type recommended by the manufacturer.

Dispose of used batteries according to the manufacturer's instructions.

Check Network Wiring

Use the Right Wire

In order to ensure optimum performance over the full range of your installation

topology, Crestron Certified Wire, and only Crestron Certified Wire, may be used.

Failure to do so may incur additional charges if support is required to identify

performance deficiencies because of using improper wire.

Calculate Power

CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to

do so could cause equipment damage or void the Crestron warranty.
