5.4 Connecting the interface cable
The connection between the computer and the FF-SE is accomplished via a RS232 cable with a 9-pin DSub plug. This
cable is available from Honeywell and is included with the software kit.
To connect the computer interfaces to the FF-SE do the following :
1. To avoid any short-circuits, ensure power is not applied to the sensor and the computer. Ensure the sensor is properly
grounded.

2. Connect the RS232 cable to the «Interface» connector of the FF-SE and hand tighten.
The sensor conforms to sealing class IP 65 / NEMA 4, 13 only if the interface connector is covered with the female
connector or with a cap.
3. Ensure the PC is connected to electrical ground (except for portable PC).
4. Connect the other end of the RS232 cable to the serial port of the PC. Notice the number of the port to which the cable
is connected. The port number will be required when setting the parameters of the software.
