Wiring of RS232 (upper) and RS422 (lower) cables.
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.
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.
Power
• DC Input: 9-18 VDC
• Battery DC-input: Nominal voltage: 13.5-18V
• Absolute maximum DC input voltage: 18.6 V
On-line Interface Box
For cables longer than 50 m the online cable can
be connected to shore to an Interface Box which
supplies 48 VDC power and RS422
communication. In the instrument, a DC-DC
converter is used to reduce the supply voltage to
15 V. Online cable systems are conceptually quite
simple, but in real life, they are both a technical
and practical challenge. We have taken many
years of experience and designed what we
believe to be a very good solution. More
information about the Interface Box can be found
on our website.

product with a non-PC controller, a

Integrator Manual is available on the website.
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.
