5. Temperature Probe Ports

   Details

   There are three ports on the RA* Head unit for connecting the supplied digital temperature probes. Any probes that you wish to utilize must be connected PRIOR TO applying power or they will not be recognized by the RA*. If connected after the unit is powered, they will be non-functional and no temperature readings will occur from that temperature probe.

7. Input Ports

   Details

   There is no polarity on the input ports. The input ports are designed for ATO usage and are distributed into three groups of two adjacent pins. The connector is a spring loaded screw-less connector. To engage your wiring, use a small tool such as flat screw driver and insert it into the slot of the orange tab above the respective port and press inwards (about 1/8"). Insert your wire, stripped to 1/2", into the port and release the tab.

   Ports 5+6 - Alarm

8. Output Port - RJ-45 connector - Be sure to pay attention to the port polarity

   Details

   The Outport uses a standard RJ-45 connector for ease of breakout. It has no Ethernet functionality. An option for utilization is to connect it to an RJ-45 breakout board (commercially available - not included) to simplify your assemblies.
