Prerequisites: 

• Required installed hardware:
  • EG4xxx or newer eGauge meter
  • eGauge Sensor Hub (ESH044)
• Only use straight-through RJ11 cables to connect powered sensors to the Sensor Hub. See this article for more information on verifying the correct RJ-11 wiring. Every Sensor Hub compatible sensor sold by eGauge Systems comes with a straight-through RJ-11 cable.
• It is not advisable to extend the RJ11 leads from the Sensor to Sensor Hub. It is acceptable to use a longer RJ45 cable from the Sensor Hub to the eGauge.
• If RJ11 cable between Sensor and Sensor Hub must be extended, it is advisable to use twisted pair wires, such as a CAT5 cable with RJ11 plugs (most commonly used for DSL modems).
• If terminating own cables, both RJ11 and RJ45 cables should be straight-through cables, with the same color order on both ends.
• ELV2 is compatible with 0-2 Vdc Dry contact sensors with ≤ 50Ω output.

Instructions: 

Step 1: Connect the ELV2 Sensor to an available RJ11 port on your Sensor Hub using the included RJ11 cable. Be sure to adjust the selector switch on the Sensor hub port to the left and plug the breakout cable2-pin connector with the same color into an available sensor port on your eGauge.

Step 2: Connect the ELV2 to the 0-2V sensor output using the signal and ground ports on the ELV2. The 5V pin is unused.

Step 3: Configure the sensor in the eGauge configuration. Please see this article for more information regarding configuration of CTid sensors.

Troubleshooting and Tips

• Issue: What do I connect to the +5V port on the ELV2?
  • Solution: This port is unused on this sensor. eGauge produced sensors use the same form-factor case so there are some cases where all ports are not used.
