USING THE 1260-100/101
To verify that the plug-ins are operational, send the MOD:LIST?
command to the Option-01T. Then read back the response of the
Option-01T. The Option-01T responds with a message specifying
which plug-ins and 1260-Series modules are under its control. If
the Option-01T does not respond, or does not properly list the
installed switch products, refer to Appendix C: Troubleshooting .
To use the message-based mode of communication, refer to
Chapter 2 of the Option-01T Instruction Manual for general
commands. For module-specific commands, refer to the individual
manuals for the plug-ins.
For high-speed operation, use the register-based mode with Racal
Instruments VXI plug&play drivers. For detailed information, refer
to the VISA and the VXIplug&play Software section of Chapter
2: Using the Option-01T in the Option-01T Instruction Manual.
To enhance safety in applications that involve power switching,
certain Adapt-a-Switch plug-ins and conventional 1260-Series
modules offer an emergency reset function, activated by an
external input. This function instantly opens all relays in response
to an external event. This is a hardware operation that does not
require intervention on the part of the Option-01T or application
software.
When using the emergency reset feature, exercise due caution if
any undesirable effects may result from opening all channels.
