Operation

GPIB Operation

Device Device Trigger will implement the most recently programmed values whether the Trigger unit is in local or remote control. If the power supply is in local mode, the new values

will be implemented when it is switched from local to remote control. Device Trigger is typically used to synchronize the operation of a number of addressed devices.

Example: Use HOLD Command to set values to be executed when triggered. See “Command Reference” on page 43.

Then use:.

ibfind "devname"	Address the unit (devname or device name as
	configured originally with ibconf)
ibtrg	Command directed to entire bus, or
ibwrt"trg"	Command directed to a specific device.

Parallel Poll Parallel Poll allows the computer controller to determine quickly which of a number of instruments on the bus requested service. The parallel poll response corresponds to bit 7 of the serial poll status byte. Parallel Poll does not reset the service request. The power supply must be configured remotely to respond to a parallel poll with either a "1" or "0" on one of the DIO lines if the unit is requesting service.

Example:

ibrpp Conduct a parallel poll.

Local Send Local Lockout from the computer controller to override the front panel Lockout LOCAL switch and ensure that the supply operates in remote mode. See “Setting

Local Lockout” on page 27 for more information.

Example:

ibfind GPIB0	Address the computer controller
ibsic	Put the controller in charge by sending an
	Interface Clear
ibsre1	Asserts Remote Enable
ibcmd "?_@\x11"	Send commands (UNL, UNT, MTA0, LLO) in
	ASCII.

Note: To disable Local Lockout, use ibsre0 in place of ibsre1 in the example.
