Diagnostic/service port connections
The diagnostic / service port generally remains unconnected during normal operation of the
Tankvision Gauge Link. The port has a 9 way “D” type socket connector. A suitable cable with
mating plug will be required for local connection of a service laptop PC or similar.
A “standard” serial port, a 9 way fully wired plug – socket cable will be required. The cable
should be wired pin-to-pin, i.e. 1-1, 2-2, 3-3, … 9-9. Proprietary cables will generally have
all pins wired, though only pins 2, 3, 4, 5 and 7 are actually used. Cable length should not
exceed 2 metres (6,6 ft).
