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:

LLO	Set Local Lockout
GTL	Return the power supply to local mode. Local
	Lockout is still in effect
REN OFF	Turn off Local Lockout and return the power
	supply to local mode

RS-232 Connection

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.

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.
