IEEE-488.2 Common Commands

3–56 VX4380 256-Crosspoint Relay Matrix Module User Manual

All sections on all scanner modules are disjoined

All sections of all VX4330 Modules are set to operate in the mux mode

Close dwell time of all modules is set to 0 seconds

Open dwell time of all modules is set to 0 seconds

All relays on all modules are opened when power is removed from the VXI

chassis

*SRE <mask>

Service Request Enable (SRE) register. This command defines a mask that is

ANDed with the contents of the Status Byte register. If the result of this

operation is non-zero, the Option 01 generates a VXI Request True interrupt.

Bits 0, 1, 3, 6, and 7 of the SRE register are not used. Bits 2, 4, and 5 are set to

enable VXI Request True interrupts to be generated under the conditions listed in

the following table.

Bit No. Meaning

bit0 (LSB) Not used

1 Not used

2The Error/Event queue contains one or more error messages

3Not used

4The Output queue contains one or more query responses

5The contents of the Standard Event Status register ANDed with the

contents of the Standard Event Status Enable register produces a

non-zero result.

6Not used

7 Not used

*SRE?

Service Request Enable (SRE) query. This command returns the value of the

Service Request Enable register as a numeric value from 0 to 255. Bit 6 is

unused, and is reported as zero.
