Closing a Relay

Getting Started 2-6
In this example, the plug-in is Model 1260-121A. Lines 3 and
4 indicate the status of the plug-in (discussed later).
3. Rotate the knob one "click" to the right (clockwise) to check
the contents of the next slot (slot 2):
----OPERATIONS----
>Slot 02: 1260-138A<
Channel: 0
Status: Open
The plug-in is Model 1260-138A.
4. Continue to rotate the knob to view the contents of the
remaining slots.
If any of the installed switch modules do not appear on the display
as you scroll through the slot numbers, refer to Appendix C,
TROUBLESHOOTING to correct the problem.
To use the IEEE-488 or RS-232 interfaces to verify plug-ins, see
Chapter 5, SCPI COMMAND BASICS. Look under the heading
Checking for Installed Plug-Ins.
The front-panel controls may be used to close relays on the plug-
ins. For example, suppose a Model 1260-118 plug-in is installed in
slot 3. To close relay channel 4 on this plug-in, proceed as follows:
1. Press the first key next to the display. Rotate the knob until
the top line reads:
>----OPERATIONS----<
2. Select line 2 (next to top line) by pressing the second key
(just below the first one). This highlights line 2 (indicated by
the ">" and "<" markers) so that you may select the slot to
work with:
----OPERATIONS----
>Slot 01: 1260-121A<
Channel: 0
Status: Open
3. Rotate the knob until line 2 shows the contents of slot 3:
----OPERATIONS----
>Slot 03: 1260-118 <
Channel: 0
Status: Open
