Installation and Configuration
Configure for Multichannel Operation
CANbus The CANbus port consists of two 4-pin modular "handset" jacks to support daisy
chain connections. The CAN (Controller Area Network) is an ISO standard
(ISO11898) for a serial communication network.
functions. The CANbus is used for communications in multichannel operation or
current sharing (master/slave) operation.

CANbus

The custom CANbus cables shipped with your unit are parallel 4-connector cables
with 4-pin modular "handset" connectors.

Configuration The CAN-only interface cards must be configured via the CANbus with another
GPIB-M card. The CAN-only interface cards are set to multichannel address 2 at the
of CAN-only
factory. Ensure the multichannel address on the GPIB-M is set to an unused address,
Interface
for example, address 1. Connect the two power supplies as shown in
Cards
"Connections for Multichannel Operation" on page
Send the query to the CAN-only power supply:
SYST2:REM:SOUR?
and ensure the response is "MCH" for multichannel.
If necessary, set the power supply to accept control via multichannel commands
(the CANbus interface) with the SCPI command:
SYST2:REM:SOUR MCH
Set each slave's unique multichannel address using the command:
SYST2:COMM:MCH:ADDR <multichannel-address>
where multichannel-address is an integer in the range of 1-50.
This procedure can be repeated separately with each power supply to assign a unique
address to each. Once all power supplies are configured, they can be connected to the
CANbus network.
