Troubleshooting
Problem
Possible solutions
The instrument
does not connect to
the PC application
over RS-232
connection.
1. Make sure that the cable is properly connected to the instrument
Check that the cable M12 circular connector is firmly connected and screwed
to the instrument. It is not sufficient to simply attach the cable connector to the
instrument connector, the cable connector must be screwed into the instrument
connector.
2. Check power supply
Make sure that the power is being supplied to the instrument. A direct-current
voltage, between 9 and 27 Volts must be connected to brown (+) and white (-)
wires of the instrument cable. The power supply must be able to deliver at least
500 mA of current.
3. Check RS-232 connector
The yellow, green and grey wires from the instrument cable must be properly
connected to the serial port on the computer. Make sure that the grey wire (signal
ground) is connected – the RS-232 connection will not work if the signal ground is
not connected. Also, make sure that the yellow (device Rx) and green (device Tx)
are properly connected. If you are using a standard DB9 type connector on the PC
computer, the wires should be connected like in the following diagram:
4. Make sure that you are using the correct COM port
If there are multiple COM ports available on your computer, make sure that you are
selecting the correct COM port in the PC application. If you are not certain which
COM port number is assigned to the COM port that is being used to establish a
connection with the instrument, try setting up the connection with each COM port
available in the system, until the connection is established.
