I. Programming CV’s & Values: Optional/Not Required!
Specific DCC Systems need to follow specific programming sequences to reliably
program a PSX-AR. See Section M for specific system instruction
The easiest way to program PSX-AR circuit breakers is at your work bench. Programming
CV values is done using the Programming On Main [POM] function. Refer to your DCC
system manual for specific directions on how to perform Program On Main functions.
1. Turn off power to the PSX-AR
2. Place the J3 programming jumper on pins J3-1 & J3-2
3. Connect the DCC track power output of your DCC system to pins J1-4 and
J1-3.
4. Turn power on to the PSX-AR.
5. Go into Program On Main mode [POM] for your particular DCC system. See
Section K.
6. Enter any address NOT in use on the layout. The PSX-AR does NOT use
this address, but the POM function requires an address.
7. Enter the CV number followed by the value. The small red LED [D6] on the
PSX-AR will blink each time a command is accepted and the CV value is
stored correctly in the CV.
8. If you make a mistake, don’t worry, just go back and program the CV to the
desired value.
9. If you are hopelessly lost, set CV63 to 42 and you can start over again with
factory default values.
10. When done, turn power off.
11. Replace the program J3 jumper to pins 2-3.
12. Turn power to the PSX-AR off.
*Caution: continuous operations at a value higher than CV49=08, [10.2 amps] without the addition of heat sinks to the
output transistors may overheat or damage the PSX-AR. Heat sinks are available from DCC Specialties. PSX-AR’s
can also be ordered with heat sinks installed.
For all systems, whenever you enter an address or CV value, you should see D6 flash. This indicates
the PSX-AR has received the information, stored it, and verified the stored data match the data you sent.
