2. There are two Remote modes:
1. Remote:
In this mode, return to local can be made by the front panel REM/LOC or via
serial port command RMT 0. Set the unit into Remote mode via serial port
RMT 1 command.
2. 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 power until the display turns off and then
recycling AC power. In local Lockout mode, the front panel REM/LOC button is
not active. Set the unit into Local Lockout mode via serial port RMT 2 command.
RS232/485 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.
Serial commands may be sent to set the status registers and read them while the unit is in Local mode.
If the Enable registers are set (refer to Section 7.8) the power supply will transmit SRQ’s while in Local
mode.
Front panel in Remote mode
Front panel control in Remote mode is disabled except for:
1. PREV: use to preview the Voltage and Current limit setting.
2. OVP/UVL: use to preview the OVP/UVL setting.
3. LOC/REM: use to set the unit into Local mode.
In Local Lockout mode, only PREV and OVP/UVL are active.
