PC adapter (converts sensor data output to RS232 for PC)
The 9 Way D-type plugs into the PC com port and the pre wired sensor connector is
inserted into J1 on the sensor PCB. When HyperTerminal on the PC set at 4800 baud (no
handshake) and connected to the com port, the PC should now display the continuous
sensor output .
When programming the sensor processor, the Run and Prog slide switch SW2 is set to
Prog but under normal circumstances, this switch should be in the Run position.
The Reset push button SW1 when pressed gives a hardware reset to the sensor processor.
This can be pressed at any time and the sensor reacts in the same way as if it had reset
itself.
