The unit will be put into Remote mode only via serial communication command.

Commands that will put the unit into Remote mode are:

OUT n

(for values of "n", see Tables 7-4, 7-5 and 7-6)

There are two Remote modes:

a) Remote: In this mode, return to Local can be made by the front panel REM/LOC

button or via serial port command "RMT 0". Set the unit into Remote mode via the

serial port "RMT 1" command.

b) Local Lockout: In this mode the unit can be returned to Remote mode via the serial

port "RMT 1" command or by turning off the AC Input power (until the Front Panel

display turns off) and then recycling AC Input power. In local Lockout mode, the front

panel REM/LOC button is not active. Set the unit into Local Lockout mode via the

serial port "RMT 2" command.

8.2.6. RS-232/RS-485 Port in Local Mode

When the Power Supply is in Local mode, it can receive queries or commands. If a query

is received, the Power Supply will reply and remain in Local mode. If a command that

affects the output is received, the Power Supply will perform the command and change to

Remote mode.

1. PREV: use to preview the Output voltage and Output current limit setting.

2. OVP/UVL: use to preview the OVP/UVL settings.
