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 of Output voltage and Output current.
– Remote voltage or resistive programming of Output voltage and Output current.
– 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 RS-232 and RS-485 communication interface.
– Enable or Disable the rear panel Enable/Disable control (dry-contact).
