Factory Repair Service
If desired, equipment items or assemblies may be returned to the PESA
factory (transportation prepaid) for repair. Refer to the General Assistance
and Service Information Sheet found in the front of this manual. Call the
PESA Service Department (the phone number is listed on Service Infor-
mation Sheet) for a RMA number prior to shipping an equipment item to
the PESA factory for repair.
NOTE
PACK THE EQUIPMENT SECURELY AND LABEL WITH THE CORRECT ADDRESS.
PROPER PACKAGING SAVES MONEY. THE SMALL AMOUNT OF EXTRA CARE AND
TIME IT TAKES TO CUSHION A PART OR UNIT PROPERLY MAY PREVENT COSTLY
DAMAGE WHILE IN TRANSIT. MAKE CERTAIN THAT THE ADDRESS IS BOTH LEG-
IBLE AND COMPLETE. FAILURE TO DO SO OFTEN RESULTS IN DELAY OR EVEN
LOSS.
Troubleshooting
Troubleshooting the RCP-GPIO Control Panel requires the routing
switcher system to be used as a test fixture. The RCP-GPIO Control
Panel will not function except as part of routing switcher system. The only
troubleshooting which can be accomplished without opening the control
panels is to check input power (from plug-in power supply).
To open a control panel for troubleshooting, remove the front cover and
disassemble the unit as far as required to gain access to the component
side of the circuit assemblies. Place the disassembled panel on a noncon-
ductive surface and arrange the parts so the unit can be operated. You
must be able to check the operation of the inputs and outputs while ob-
serve the resulting status. You must also have sufficient access to the
circuit assemblies to measure voltage or observe waveforms.
Procedure:
Put the RCP-GPIO Control Panel through the operating
sequence as described in operation section of this manual. Refer to Sec-
tion 3.
If the control panel is unresponsive, there may be a power problem
or the microprocessor on the GPIO Interface Card is not operating.
