6. Remote Programming Operation

6.0.

This Series Electronic Load supports both local operation and remote control. The previous chapter has

introduced how to use the front panel keys and knobs to operate on the load. This chapter will introduce you

to how to use the load from the remote controller. The similarities between local and remote programming

will become apparent as you read this chapter. The intent of this chapter is to help users quickly become

familiar with remote programming operations. Programming examples given in this chapter use the SCPI

commands in their simpliest form. Please refer to the “Electronic Load SCPI Programming Guide” for

detailed introduction of all SCPI commands.

6.1. Communication Interface

RS232 interface is standard. Use the cable shipped with the load to connect the load to a computer correctly.

Set the baud rate, parity, data bit, and stop bit parameters. Set the same parameters in the software on

the computer, and input the right SCPI command to operate the load.

6.2. Remote Control Annunciators

There is a Rmt remote control annunciator on LCD. When the load receives the remote command (SYS-

Tem:REMote) via RS232 interface, the Rmt remote control annunciator turns on. In remote control status,

all operations on the load are controlled by the remote controller; the front panel keypad and knob has no

effect (except “Lock/Local” key). The R Rmt remote control annunciator turns off and the load returns to

the local control after receiving the command to return to local control (e.g. :SYST:LOC). Or you can return

the load to local control from remote control by long-pressing “Lock/Local” key.

6.3. Sending a Remote Command

You can use the computer to set operation mode and operation parameters remotely for the load.
