2.1.6 External User Control Signal Connector
The external user control signal connector described in the M130/M131 Programming
Manual, P/N M362797-03, and in the M9G manual, has been changed as it applies to
the M6 Option. The end user will no longer have access to the following signals:
These signals are now utilized solely by the M6 card. The other signals remain as is.
An 8-pin Molex or 9-pin Subminiature-D connector located at the rear panel provides
external auxiliary control signals to increase the user's operating control of the supply.
The mating receptacle for the 8-pin connector is Molex 43025-0800 with 8 female
terminals 43030-0003. The Molex terminals accommodate wire sizes from #20 - #24.
The relay outputs, when active, connect the POLARITY, SENSE, and ISOLATION pins
of the connector to the relay COMMON pin. The relays are rated at 120VAC/125VDC @
1A; for DLM Series 600W, maximum ratings are 60V(PK), 30VA, and 1A.
Any change in output (voltage, current, etc.) initiated by the user from the RS-232, GPIB,
or Ethernet interface will cause a 10ms synchronization pulse to be generated at the rear
panel User Control Signal Connector of the master unit (Sync Signal).
