Making communication cables for J-Suffix Sensorsoft Devices
In some applications it’s 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, ceilings or conduits
where connectors would get jammed. In this situation it makes sense to terminate the cables on-
site using hand crimp tools. The following details will assist you in this process.
NOTE
- A J-suffix Sensorsoft Device has a RJ45 jack connector. It
accepts a plug-in cable. This includes models
ST6105J
and
ST6154J
.
Figure 3: Illustrates a J-suffix Sensorsoft device that accepts a cable with RJ-45 plug.
IMPORTANT
- A properly made cable will allow your Sensorsoft device
to operate reliably over long cable lengths up to 305 m (1000 ft) using
SSDP-compliant software.
You may connect the Sensorsoft device to the port with as little as three wires (RX, TX and
GND), using inexpensive unshielded telephone wire. However, the host may need to set the
number of retries high in order to overcome the effect of occasional noise/interference and would
require the use of an external power supply (PA6106 or PA6206) at the Sensorsoft device.
