Installation and Configuration

Configure for Multichannel Operation

A power supply will attempt to connect to the network:

on power up, and

when the multichannel address is changed.

The power supply will successfully connect if there are no other power supplies on the network with the same address.

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 4.5, “Remote CONtrol Sub-Register,” on page 74 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.1, “IEEE 488.2 Commands,” on page 104.

Note The multichannel interface can not handle multiline response messages.
