Our client has a PSR1212 that is being controlled by an AMX Control System via RS-232. One of the functions of the control system is to select presets on the PSR1212, but sometimes the unit ignores the command and does not change presets. Can anyone please assist?

TechRon,

Here is an excerpt from the PSR1212 manual regarding how to call presets:
PRESET - Preset Execution/Reporting
This command selects/reports the state of a preset.
Command form: DEVICE PRESET <Channel> [Value]
Argument details
Name Description
Device 0–7 or * to select all units
PRESET Command
Channel 1–32 (select preset)
Value 0 =Set the preset state to off
1 = Execute the preset and set the state to on
2 = Execute the preset and set the state to off
Null = Returns the current preset state
Example: #42 PRESET 5 1 On PSR1212 unit 2 (#42), preset (PRESET) 5
will execute and set the state to on (1).

The short explanation here is that there are three ways to call a preset depending on how you want the preset "state" to be set. If the preset state is set to "On" then the next time that preset is called it will NOT run. In order to be able to run the preset again you will need to make sure the preset state is "Off".

The example from the manual will run the preset and turn the state to "On". If you use this command instead
#42 PRESET 5 2
this will run the preset and turn the state flag to "Off".

If you want to be sure that the state flag is "Off", you can run this command:
#42 PRESET 5 0
This will not run the preset, it will just turn the state flag "Off".

IN SUMMARY, you can insure that your presets will always run if you always call them with the state value of "2" (#42 PRESET 5 2). If you use the state value of "1", then you need make sure that you turn the preset flag off before trying to run it again.

I don't program AMX only Crestron sounds like it is exactly as tech supports says the programmer is calling out the wrong preset state.
