IGURE A-6: ADDING AN AGILENT 87104A RELAY AS “SW1”

When a relay is selected in the System Explorer, various properties can be viewed and edited. By

default, the relay will be added to the lowest available drive line. This can be modified to fit the

user’s setup by changing the value in the First drive line drop menu. In addition to changing the

relay drive line, user’s can change the name of the relay, the reset drive line, and the wire

connectivity as well.

NOTE The EX72SF and the EX72CC are supplied from the factory prewired for the connections between

the front panel switches and the RDB drive lines. Thus, SW1 must be configured to use drive line

K1-1; SW2 must be configured to use drive K1-7, etc. Table 6-1 provides the required starting

drive lines associated with each front panel switch position.
