Local

Lockout

(LLO)

Command

Use the Local Lockout command to disable the LOCAL button on the power

supply front panel. With LLO in effect, you cannot return to local control by

pressing the front panel LOCAL switch. You can still return to local mode by

sending the Go to Local (GTL) command. To turn off LLO and return the power

supply to local mode, send the REN OFF command. Only the REN OFF command

will remove the LLO condition.

Example:

RS-232 Connection

Use an approved RS-232 connector and cable when connecting the RS-232

Interface to your computer. The RS-232 connector uses the 9 pin mating connector

J5 on the rear panel. Figure 2.4 shows the connector pinouts for the RS-232

connector. Refer to Figure 2.2, on page 21 for the position of the RS-232 connector

on the rear panel subplate.

WARNING

Do not operate the power supply and the computer at significantly different frame

potentials. The interface connection system may not be capable of handling the

resulting excessive ground currents.
