Model NV-EC1701 EoC Ethernet over Coax Transceiver
with PoE, PoE+, or High Power PoE
The NV-EC1701 has a power inlet connector that receives 48 or 56 volts from an external Class 2 SELV desk-style power supply.
Power is distributed to:
1) the transceiver’s internal electronics;
2) the RJ45, provided the connected camera or other device provides the appropriate 27K ohm PoE ‘discovery signature’.
+48V (or +56V) power is provided on pins 1&2 and 5&4, while 3&6 and 7&8 are at 0 V. The use of all four wire-pairs ensures
maximum distance, even for high-power loads, such as P/T/Z cameras.
3) the coax cable, where it is used by the control-room NV-EC1701.
For fault/safety, never use more than two power supplies within a network.
