7.2.3 RS232 or RS485 selection
7.2.4 Baud rate setting
7.2.5 Setting the unit into Remote or Local mode
The power supply address can be set to any address between 0 and 30. Follow the instructions
described below to set the address.
1. If the unit is in Remote mode (front panel REM/LOC LED illuminates), press REM/LOC
button to put the unit into Local mode.
2. Press and hold for approximately 3sec. the REM/LOC button. The VOLTAGE display will
indicate the communication port address.
3. Using the VOLTAGE adjust encoder, select the address.
To preview the address at any time, press and hold the REM/LOC button for approx. 3sec. The
VOLTAGE display will indicate the power supply address.
To select between RS232 or RS485 set the rear panel setup switch SW1-6 position to:
- Down for RS232
- Up for RS485
Five optional rates are possible: 1200, 2400, 4800, 9600 and 19200. To select the desired rate,
the following steps should be taken:
1. If the unit is in Remote mode (front panel REM/LOC LED illuminates), press REM/LOC
button to put the unit into Local mode.
2. Press and hold for approx. 3sec. the REM/LOC button. The CURRENT display will show
the communication port Baud Rate.
3. Using the CURRENT adjust encoder, select the desired Baud Rate.
1. The unit will be put into Remote mode only via serial communication command.
Commands that will put the unit into Remote mode are:
RST
PV n
OUT n
PC n
RMT n
