3-28 Operation
*RST — reset
When the *RST command is sent, the relay unit performs the following operations:
1.
2.
3.
*SRE <NRf> — Service Request Enable
*SRE? — Service Request Enable Query
Parameter
Use the *SRE command to program the Service Request Enable Register. Send this
command with the decimal equivalent of the binary value that determines the desired state
(0 or 1) of each bit in the register. This register is cleared on power-up.
This enable register is used along with the Status Byte Register to generate service
requests (SRQ). With a bit in the Service Request Enable Register set, an SRQ occurs
when the corresponding bit in the Status Byte Register is set by an appropriate event. For
more information on register structure, see the information presented earlier in this
section.
