Cables
Our instruments are mostly shipped with RS232
communication. RS422 is used for cables longer than
50 m. The wiring is shown in the tables to the right.
The output can either be in ASCII, in fixed NMEA
format, or binary format.
Communication baud rate: 300-115200 (user setting).
Recorder download baud rate: 600/1200 kBaud.
Ensure that the connectors and dummy plugs are
lubricated with dielectric silicone. We recommend 3M
silicone spray. Note that the silicone grease included
in the shipment should be used on the O-rings only.
Analog Input (default for most instruments)
The instrument can read two analog inputs at the
same time. The input range is 0-5V, corresponding to
0-65535 counts in the data file.
Power
• DC Input: 9-16 VDC
• Battery DC-input: Nominal voltage: 13.5-18V
• Absolute maximum DC input voltage: 18.6 V

Troubleshooting
As most problems are caused by simple mistakes,
please initially check if
• you have forgotten to power the system
• the connector has fallen out of the computer
• you are using the wrong serial port
When all obvious mistakes are ruled out, please turn
to our Troubleshooting Guide. The FAQ site may
also be helpful.
