Controller Connections; Gpib Connector; Rs-232 Interface - Agilent Technologies 6811B User Manual

2 - Installation
In example B, the FLT output of one unit is connected to the INH input of another unit. A fault condition
in one of the units will disable all of them without intervention either by the controller or external
circuitry. The controller can be made aware of the fault via a service request (SRQ) generated by the
Questionable Status summary bit.

Controller Connections

The ac source connects to a controller either through a GPIB or an RS-232 connector.

GPIB Connector

Each ac source has its own GPIB bus address. AC sources may be connected to the bus in series
configuration, star configuration, or a combination of the two. You may connect from 1 to 15 ac sources
to a controller GPIB interface.
NOTE: The ac source is shipped from the factory with its GPIB address set to 5. This address
can be changed as described in Chapter 4 of this guide.
