5. Remote Operation

The DB9 interface connector on the rear panel of the power supply can be connected to a RS-232 or USB

interface via the included adapter cable. This chapter describes how to use a computer to control the output of the

power supply.

5.1 Communication cable

RS232 Communication cable IT-E131

The DB9 interface connector on the rear panel of the power supply provides a TTL voltage level interface. Use

the communication cable (IT-E131) to connect the DB9 interface connector of the power supply to the RS-232

interface connector of the computer

It is

not possible

to connect the DB9 connector of the power supply directly to a PC’s

RS232 or USB port.

USB Communication cable IT-E132

The DB9 interface connector on the rear panel of the power supply provides a TTL voltage level interface.

Use

the communication cable (IT-E132) to connect the DB9 interface connector of the power supply to the USB

interface connector of the computer.
