comes on and the RI bit is set in the Questionable Status Event register. To re-
enable the unit, first open the connection between pin + and GND pin and then
clear the protection circuit. This can be done either from the front panel or over the
IEEE-488 or RS-232C bus.
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.

2.12 Controller Connections
The iL Series comes standard equipped with both IEEE-488 and RS232C remote
control interfaces, both of which are accessible from the rear panel. Either interface
can be used to connect the AC source to a controller.
2.12.1 IEEE-488 Connector
Each AC source has its own IEEE-488 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 IEEE-488 interface. The
AC source is shipped from the factory with its IEEE-488 address set to 5. This
address can be changed as described in section 4.10 of this manual.
