Functional Verification
The Functional Verification Test for the relay multiplexer module consists of
sending the *TST? command and checking the response. This test can be used at
any time to verify that the device is connected properly and is responding to
basic commands.

Procedure

1 Verify that the relay multiplexer is installed in the mainframe and that the
2 Send the *TST? command to the device (see example following).
3 The device will return an error code. Any non-zero error code indicates a

Example

An example follows which uses an HP 9000 Series 300 computer with BASIC and
a multiplexer address of 70914.
A typical response is:
