7.9.2.4 Enable SRQ retransmission (MD MODE OPTION REQUIRED)
Enable retransmission of SRQs. This is only available when the Multi Drop Mode is enabled
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 sup-
ply address, until answered. All supplies, both the currently addressed supply and all non-
addressed supplies, will enable SRQ retransmission as a result of this command.
7.9.2.5 Enable FLT Bit in the SENA Register
The Hex value of the command is 0xA4. Send it two times in sequence.
7.9.3 Global commands with response
7.9.3.1 Disconnect from communications
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 supply. After receiving
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-addressed supplies,
will respond to this command; but only the currently addressed supply (if any) will respond
with the ‘OK’.
7.9.4 Addressed commands with response
7.9.4.1 Read registers
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
register data, a single dollar sign, $, will be added to signal the end of data and the start of a
checksum. The checksum will be the sum of all register data and will be represented in two
Hex bytes. The transmission will end with the CR character. If repetitive sending of SRQs
was active and the supply was sending them, the supply will stop sending repetitive SRQs
but leave the function active. The contents of the registers will not be destroyed. Note that
the supply does snot have to be the active addressed supply.
Note that this command will not execute if another command is being processed.
7.9.4.2 Print Power On Time
Print the total time the supply has operated under AC power. Send 2 bytes in sequence, A6
Hex and the address of the supply in binary. A 32 bit integer will be returned in 8 Hex bytes.
The data will be the number of minutes that power has been ‘ON’ in the supply in binary. A
‘$’ sign and 2 byte Hex checksum will be appended to the data. There is no method pro-
vided to reset this number.
Retransmit last message.
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 sup-
ply.
This command will not execute if another command is being processed.
Note that Single byte commands do not load data into the supply’s data output buffer.
Thus this command will not cause the supply to retransmit data obtained from any previous
Single Byte Command.
