7.10.5.1 Acknowledge SRQ
Send (0xE0 + Address) (1 byte binary - send 2 times sequentially). The supply will stop re-
sending SRQ. If Enable SRQ retransmission is active, it will remain active.

Send A5 Hex followed by the address of the supply in binary and new SRQ’s generated by
new events in the Fault Event will be enabled without reading and clearing the Status Event
Register. All events previously recorded in the Fault Event Register must have been serviced
by the user’s software prior to this command to take affect.
