4.4 REAR PANEL SW1 SETUP SWITCH

The SW1 Setup switch (see Fig.4-3) is a 9-position DIP switch that allows the user to choose the
following:
- Internal or remote programming for Output Voltage and Current Limit.
- Remote voltage or resistive programming of Output Voltage and Output Current limit.
- Select range of remote voltage and resistive programming.
- Select range of Output Voltage and Output Current monitoring.
- Select the Remote Shut-Off control logic.
- Select between RS232 or RS485 communication interface.
- Enable or disable the rear panel Enable/Disable control (dry contact).
