The VS-2A can also be controlled via a serial device. The unit operates at
a baud rate of 4800 bps. From the serial port, you have full control over
the operation of the switched output, mode, and priority buttons.
Note on RS-232 port availability on your PC
Most PCs and notebooks do not have a
serial port. So to program the Switch you
may need a USB to RS-232 Serial
converter. These are available from Hall

will also be displayed when a proper command is sent to it via a serial
