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 mainframe has passed its power-on test.

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 self-test failure. See Table 4-5 for a description of self-test

error codes.

Example An example follows which uses an HP 9000 Series 300 computer with

BASIC and a multiplexer address of 70914.

10 DIM A$[50]

20 OUTPUT 70914;"*RST;*IDN?"

!Module identification

30 ENTER 70914;A$

40 PRINT A$

50 OUTPUT 70914;"SYST:CDES? 1" !Module Description

60 ENTER 70914;A$

70 PRINT A$

80 OUTPUT 70914;"SYST:CTYP? 1" !Module Type

90 ENTER 70914;A$

100 PRINT A$

110 OUTPUT 70914;"*TST?" !Send the self-test command.

120 ENTER 70914;A !Get response.

130 PRINT A

140 END

A typical response is:
