Enable SRQ retransmission (MD MODE OPTION REQUIRED)
Enable retransmission of SRQs. This is only available when the Multi Drop Mod
in the supply. The Hex value of the command is 0xA3. Send it two times in sequence. If the
supply sends an SRQ it will be repeated on a timely basis, 10 ms plus 20 ms times the su
ply address, until answered. All supplies, both the currently a
ddressed supply and all non
addressed supplies, will enable SRQ retransmission as a result of this co
Enable FLT Bit in the SENA Register
The Hex value of the command is 0xA4. Send it two times in sequence.
Global commands with response
Command the supply to end all data transmissions to the HOST PC/IEEE Board and cease
its role as the active addressed supply. The HOST PC/IEEE Board will be required to re
send the ‘ADR nn’ command to reestablish communications with the
the first command the supply will respond with an OK<CR>. The Hex value of the command
is 0xBF. All supplies, both the currently addressed supply and all non
will respond to this command; but only the currently a
ddressed supply (if any) will respond
Addressed commands with response
Send (0x80 + Address) (1 byte binary
send 2 times sequentially). The supply will return the
contents of the Status Condition Register, the Status Enable
Register, the Status Event
Register (SEVE?), the Fault Condition Register, the Fault Enable Register and the Fault
Event Register IFEVE/). All registers will be represented in two Hex bytes. Following the
ister data, a single dollar sign, $, will be ad
ded to signal the end of data and the start of a
checksum. The checksum will be the sum of all register data and will be repr
Hex bytes. The transmission will end with the CR character. If repetitive sending of SRQs
was active and the supply
was sending them, the supply will stop sending repetitive SRQs
but leave the function active. The contents of the registers will not be destroyed. Note that
the supply does snot have to be the active addressed su
Note that this command will not execut

Print the total time the supply has operated under AC power. Send 2 bytes in sequence, A6
Hex and the address of the supply in binary. A 32 bit integer will be returned in 8 Hex bytes.
ill be the number of minutes that power has been ‘ON’ in the supply in binary. A
‘$’ sign and 2 byte Hex checksum will be appended to the data. There is no method pr
vided to reset this number.
Send (0xC0 + Address) (1 byte binary
send 2 times sequentially). The supply will return
the last message sent. Note that the supply does not have to be the active addressed su
This command will not execute if another command is being processed.
Note that Single byte commands do not loa
d data into the supply’s data output buffer.
Thus this command will not cause the supply to retransmit data obtained from any previous
