SOFTWARE VERSION REQUEST (“V”) COMMAND AND RESPONSE (“B”)
The 5 byte command to request the software revision level of the power supply’s
data interface is the “V” command.
The protocol for the V command will be as follows:
The power supply will receive a V command requesting information. If the
command is properly received with no errors detected, the power supply will return
the 6 byte Version Response (B) packet back to the computer. If errors are detected
in the V command, the power supply will return an appropriate error message.
The format of the V command is:
SOH V Check1 Check2 <CR>
Entered at the keyboard:
Ctrl-A V 5 6 Enter
Sent in ASCII coded hexadecimal:
01 56 35 36 0D
where the checksum, which does not include the SOH character, will always be hex
56, transmitted in two ASCII bytes representing 5 and 6.
The format of the 6 byte Response Packet (B) will be:
B 2 byte revision level 2 byte checksum <CR>
For example, if a V command was properly received by a data interface with
software revision level 25, the following packet will be returned to the computer:
B 25 2 byte Checksum <CR>
Sent in ASCII coded hexadecimal:
42 32 35 36 37 0D
since the checksum of 32 hex + 35 hex is 67 hex which is transmitted in ASCII as
two bytes containing 36 and 37 hex.
