Multichannel Operation (6000 Watt only)

Multichannel Operation (6000 Watt only)

Multichannel Multichannel operation is only available for 6000 Watt units. You may remotely Connections control up to 50 power supplies from one programming interface (RS-232 or GPIB)

by using multichannel addressing if the CANbus option is installed.

One power supply will be connected to a PC via RS-232 or GPIB. All other power supplies are connected via CANbus (Controller Area Network) to that unit. SCPI commands that include a channel address will be sent via the CANbus to the other power supplies. (Commands with the local address will be executed locally and will not be sent).

The multichannel address must be appended to the program mnemonic. If no multichannel address is appended to the program mnemonic, the command is executed by the local (directly connected) power supply.

Each unit of the network can send and receive commands to and from other units on the network. It is highly recommended that only one command be sent at a time. Any RS-232 and GPIB timeout settings should be increased when using multichannel commands.

CANbus

The CANbus port is a one male, one female DB9 connector to support “daisy chain” connections. The CAN (Controller Area Network) is an ISO standard (ISO11898) for a serial communication network. Table 4.5 describes the pin functions. Pins 1, 4, 8, and 9 are not used. The CANbus is used for communications in multichannel operation or current sharing (master/slave) operation, and is part of the optional GPIB/CANbus interface card.
