Making extension cables for C-Suffix Sensorsoft
Devices
In some applications it is not possible to use pre-assembled cables. When installing the Sensorsoft
device at a remote location it may be necessary to run cables through walls, ceiling or conduits
where connectors would get jammed. In this situation it makes sense to run the cables and then
terminate them, on-site, using hand tools. Further, if your host serial port is of the DCE type
(some multi-port serial cards) it will be necessary to make your own cables. The following details
will assist you in doing that.
A properly made cable will allow your Sensorsoft device to operate reliably over long distances.
