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.
Serial cable not wired
correctly. Verify that serial cable is
wired correctly for RS-232,

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).
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 2-Series integrated
dual bus control system. 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.
Serial Communication Difficulties with Other
Devices Connected to the Control System
NOTE: The information below pertains to the COM Analyzer. The methods
described apply to the PRO2 only. For the AV2, use Passthrough Mode. For
information pertaining to Passthrough Mode, refer to “Passthrough Mode” in the
Crestron 2-Series Control System Reference Guide (Doc. 6256)
NOTE: Only COM-type devices and cards in the SIMPL Windows program that are
active (not commented out) are monitored.
Depressing the COM menu function button from the front panel Main Menu (default
front panel page) displays a listing of all devices and cards that can be monitored.
The listing follows the same order as the system tree in Configuration Manager. The
