Problem:
Micro Sensor does not communicate with the computer.
Solutions:
• Incorrect power is being applied to the instrument. Check with a volt meter for proper
supply voltage and polarity. The voltage range is from +8 to +16 VDC. Please refer to the
appendix 'C' Electrical Wiring Diagram.
• The serial port chosen is incorrect. Most IBM computers have only one serial port,
therefore the user should choose the COM1 setting. However, if a COM2 port exists, the
user must take care in determining which port the cable has been connected to and choose
the appropriate baud rate/port combination.
• The communications set up of the computer is incorrect. The Micro Sensor will be factory
set to no parity, 1 stop bit, 8 data bits and will automatically determine the baud rate after
the reception of an <
Enter
> or <
Ret
>.
• The baud rate of the computer was changed after the sensor was powered up. Turn the
power supply for the sensor off for at least 2 seconds and then back on. Hit the <
Enter
>
key. The instrument should then return a header.
• The communications cable has been inserted incorrectly. Check the cable connections
at the computer and the sensor. Examine the pins on the sensor connector for bent or
corroded pins.
