Pre-Installation Considerations: RTMS Echo Sensor
Cabling : ISS Provided Cable
The RTMS Echo uses an outdoor rated CAT5e or CAT6 cable that provides both power and Ethernet communications. ISS provides a cable with each RTMS Echo sensor. The cable has the following features:
- CAT5e rating
- Polyethylene jacket for moisture, water, and UV protection
- Foil shield to protect from EMI/RFI interference
- 23AWG solid connectors fit for PoE applications
- Ground wire
- 50 ft (15.24 m) in length and comes with an 8-pin RJ-45 connector on the end that connects into the RTMS Echo
NOTE: If using a 12 volt power supply it is recommended that the cable length from the power supply to the Echo sensor be no more than 50 ft (15.24 m) in length.
The connector also contains an element to which the ground wire is attached. The other end of the cable is what needs to be connected to power, communications, and ground in the breakout box. Cable pinout is a combination of standard Ethernet and custom. The green and orange pair are wired like standard Ethernet for 100Mbits per second data transfer. The wiring and pinouts for the connector are shown in the figure below.
The non-colored wire in the cable must be connected to Earth ground in the breakout box if the cable is not terminated with an RJ-45 connector. If it is terminated with an RJ-45 connector, the connector must have an element to which the ground wire can be connected, such as with the Conec 391J00039X connector.
