Status, Error, and SRQ Registers
7.11.1. General Description
This Section describes the structure and operation of the six status, error, and SRQ
registers. The registers can be set or read via the RS232/RS485 commands.
Refer to Fig. 7-7 for the Status and Error Registers Diagram.
NOTE
These registers operate in a way that is similar to the IEEE-488 and SCPI registers (as used by
the Genesys
™
with the “-IEMD” option), but the structure and command set is different.

One response for every command
or query received.
One SRQ when SEVE goes
from all zeroes to any bit set.
Setting more SEVE bits does
not cause more SRQs.
Positive Logic:
0 = No Event
1 = Event Occured
