Figure 3- 4: The Event Status Enable Register (ESER)
The Service Request Enable Register (SRER) — is shown in Figure 3--5. It
controls which bits in the SBR generate a Service Request (GPIB only) and are
summarized by the Master Status Summary (MSS) bit.
Use the *SRE command to set the SRER. Use the *SRE? query to read it. The
RQS b it remains set to one until either the Status Byte Register is read with a
Serial Poll (GPIB only) or the MSS bit changes back to a zero.

Figure 3- 5: The Service Request Enable Register (SRER)
The *PSC command controls the Enable Registers contents at power-on.
Sending *PSC 1 sets the Enable Registers at power on as follows:
H DESER 255 (equivalent to a DESe 255 command)
H ESER 0 (equivalent to an *ESE 0 command)
H SRER 0 (equivalent to an *SRE 0 command)
Sending *PSC 0 lets the Enable Registers maintain their values in non-volatile
memory through a power cycle.
NOTE. To enable the PON (Power On) event to generate a Service Request
(GPIB only), send *PSC 0, use the DESe and *ESE commands to enable PON in
the DESER and ESER, and use the *SRE command to enable bit 5 in the SRER.
Subsequent power-on cycles will generate a Service Request (GPIB only).
