Remote Operation

Multichannel Operation (6000 Watt only)

Configuration Before connecting a power supply to a multichannel network, you must configure each power supply with a unique address. The front panel or a remote interface maybe used to do this.

One power supply must be configured to operate via RS-232 or GPIB.

Front Panel

1.Select the "REMOTE CONFIG" menu

2.Select the "Multichnl Cfg" menu. Press ENTER.

3.When prompted with "Addr" enter a unique network address in the range 1–50. Press ENTER

To receive and execute commands:

1.Select the "REMOTE SELECT" menu, then select "Multichannel" from the list. Press ENTER.

SCPI

Set a slave's multichannel address using the command: SYSTem:COMMunicate:MCHannel:ADDRess <multichannel-address>

where multichannel-address is an integer in the range of 1-50, and the command is sent via a controller directly connected to the slave’s RS-232 port.

If the unit is to execute commands, set the power supply to accept control via multichannel commands (the CANbus interface) with the SCPI command: SYSTem:REMote:SOURce MCHannel

Setup 1. Connect power supplies to be controlled via the CANbus network. Parallel male DB9 to female DB9 cables (N-1) are required. Connect the power supplies in series, linking the first power supply to the second using one cable, and then the second to the third using a second cable and the second CAN port. A single ribbon cable with multiple connectors may be used instead of several cables for ease of connection. Terminate the bus at both ends with 120 ohm, 1/4 Watt resistors (included) across the CAN HI and CAN LO signals (Pins 2 and 7). See Table 4.5, “CANbus Pins,” on page 113.
