Sequence
More than one multiple channel controller may be used in a system. Multiple controllers are usually used when the distance to a switch control unit exceeds the maximum length allowed. The REMOTE 1 and REMOTE 2 connectors on the rear panel allow connections to multiple controllers. See Chapter 9, “Service” for more information on these connectors.
To set up and control the remote controller, use these commands:
•RUNTime:CONTroller
•RUNTime:TIMEout:REMote
•RUNTime:SWITch:TRIGger
The remote controllers can be triggered using the commands:
•RUNTime:SOURce:SOURCE1:TRIGger
•RUNTime:SOURce:SOURCE2:TRIGger
Issue the RUNT:INIT:IMM command to initiate the
OUTPUT 70918;"RUNT:INIT:IMM;”
Once the sequence is initiated the 85330A either:
•Waits for an event trigger before issuing a trigger to the receiver,
OR:
•Immediately issues a trigger to the receiver.
This is set using the RUNT:EVEN:TRIG command.
Refer to Figure
Idle
This is the idle state of the 85330A. This also the state the unit enters if an error occurs during
Select Switch State
The first switch state is selected for Port 1 or Port 2, as defined with the RUNT:SWIT:SCAN command. A delay now occurs to allow the switch to settle, defined with RUNT:SWIT:DEL.
