Communications Troubleshooting
Try the following procedure if you have trouble operating the Option-01T or plug-ins. If you still
have difficulty, contact Racal Customer Support Chapter 5: Product Support.
1. Turn off the VXIbus chassis power switch. Wait at least two seconds, then turn it back on. The
Fail LED on the left-most 1260-100/101 Carrier or 1260-Series module should illuminate, then
go out within five seconds. If it does, then proceed to step 2. If the Fail LED does not
illuminate when power is turned on, then go to step 6. If the Fail LED illuminates, and stays on
after five seconds, then the Option-01T may be defective; contact Racal Customer Support.
2. Send a *IDN? command to the Option-01T, then read the response. It should be in the
following format:
Racal Instruments,1260A Option-01T,<serial num>,<revision>
where <serial num> is the serial number, and <revision> is the revision level of the
firmware. If the Option-01T responds with a message in this form, then proceed to step 3.
Otherwise, go to step 8.
3. Execute the Racal Instruments 1260-Series soft front panel program. It should display a list of
all plug-ins and 1260-Series modules that are connected to the Option-01T. If it does not
display a list, then go to step 8. Otherwise, proceed with step 4.
4. If the list displayed in step 3 is complete, then go to step 5. Otherwise, go to step 10.
5. Since the list of plug-ins is complete, the Option-01T is successfully communicating with all of
the plug-ins. If you still have other communication difficulties, contact Racal Customer Support.
