PSX Address Programming

Posted by on Oct 1, 2015 in Tips DCC Components, Tony's Tips |


I have a question related to the PSX-1 Circuit Breaker..  I have ten PSX’s daisy chained together and programmed for addresses 1001 through 1010.  When I use the accy. address option on my NCE PH-Pro and turn off some of the PSX-1’s everything is fine until I turn one back on.  When I turn some ON, the previous addressed one turns OFF.  I then have to go down the “chain” of PSX’s and turn each one back on since the next lower one now turns off until the last one, 1001, does not turn off.  This doesn’t happen with all of them.

Example:  1007, when turned back on, 1006 then turns off. I then have to go through turning on 1006, then 1005, then 1004, then 1003, then 1002, but 1001 does not turn off?  Thanks…..John C.

John: OK. The problem is each PSX uses THREE addresses. If you programmed them in sequence [likely], the ON command to one is the photo cell enable to the previous one. The previous one then trips off. Here is what to do:

  1. Place the first PSX in program mode by moving the Program Jumper to PROGRAM
  2. Send an ON (1) command to the accessory address 1001, then to accessory address 2043, then to accessory address 2044.
  3. Remove power and return the first PSX’s Program Jumper to normal operation.
  4. Set the second PSX to program and turn on power.
  5. Send the ON (1) accessory command to 1002, 2043, 2044.
  6. Repeat as necessary.

This will program each of the PSX’s on/off controls to 1001, 1002, etc. while leaving the other two addresses for photo cell arm [and switch control on the PSX-AR only] at their default values. If you only send one address, the PSX assumes you want the three addresses in sequence. Send 1001 only, and 1001 is on/off, 1002 is photo cell arm, and 1003 is switch control (only used by PSX-AR but programmed in the PSX breaker). Hope this helps……Larry
