Remote Operation

Multichannel Operation (6000 Watt only)

Note that slave units have an automatic readdressing capability when in multchannel mode. A slave unit will attempt another address when it is added to a string with an address that is already taken. If no new address can be found then the following error will be queued:

Error 1702, “Multichannel address taken” is queued if the power supply fails to connect.

SCPI Remote Control (RCONtrol) subregister will indicate the status of the connection. A power supply that has been disabled will not have any bits set. Use the SCPI command:

STAT:OPER:RCON:COND?

to query the condition of the multichannel interface.

See Table 4.13, “Remote CONtrol Sub-Register,” on page 148 for a description of the bits in this register.

Multichannel To send a command to a multichannel power supply, attach the channel address to Commands the command. If no channel number is specified, the command will be executed by

the directly connected power supply.

For example, the command:

SOURCE12:VOLT 10.0

will set the power supply with address 12 to 10V output. The master receives the command and puts in on the CANbus.

Appendix B. “SCPI Command Reference” lists all commands.

[<channel>]indicates where the multichannel address is to be inserted into the command.

IEEE488.2 commands have been given an alias that is SCPI compliant if the command is applicable to a power supply in multichannel operation. These commands include *CLS, *IDN?, *OPT?, *RST, *TST?, *RCL, *SAV, *SDS, and *WAI. See Table B.9, “System Commands,” on page 204.

Note The multichannel interface may not handle multiline response messages.
