Only two of the digital connector pins on each mainframe can be configured as “ONCouple” and “OFFCouple” on each synchronized mainframe. The designated pins will function as both an input and an output, with a negative transition on one pin providing the synchronization signal to the other pins.

Front Panel:

SCPI Command:

For mainframe #1, select

System\IO\DigPort\Pin6

Select Function, then ONCouple.

Select Pin7, then select Function, then OFFCouple.

Repeat these steps for mainframes #2 and #3.

To configure pin 6 of mainframe #1 as the ON control:

DIG:PIN6:FUNC ONC

To configure pin 7 of mainframe #1 as the OFF control:

DIG:PIN7:FUNC OFFC

Repeat these commands for mainframes #2 and #3.

Operation

Once configured and enabled, turning the output on or off on any coupled channel will cause all coupled channels on all configured mainframes to turn on or off according to their user-programmed delays. This applies to the front panel On/Off key, the Web server, and to SCPI commands.

If a mainframe has its ON/OFF key coupled (located in the System\Preferences\Keys menu), turning the output on or off on any coupled channel will cause all coupled channels as well as non- coupled channels on that mainframe to turn on or off.
