When it comes to connecting the EC-xx model PoE devices, there are a couple of "modes" that these devices can be placed into. These modes are: Pass-through, Non-PoE, Multi-channel PoE/Non-PoE. Each has the description of:

  • Pass-through - this is where there is a main PoE switch that is providing power on the front end that passes through the EC-xx devices to the edge device/camera. This is literally passing the power along and extended the distance.
  • Non-PoE - this is where the EC-xx devices are locally powered from their own transformer or rack mounted cage (USRACK) and NOT through the PoE device at the head end. The EC-xx devices are generally NOT connected to a PoE capable switch in this mode as they are able to inject PoE from getting the local power from the plug-in transformer. The camera then gets the PoE from the EC-xx device.
  • Multi-channel PoE/Non-Poe - this is a combination of the above but with multiple channels for power; e.g. connected to multiple cameras that need/require PoE to operate.

In either of the instances above, you can have either "Local" or "Remote" applications and it is termed just that - local or remote. Being "local" for the EC-xx PoE device is considered to be at the head end or where the power is actually coming from, or, starting. This power source can either be a PoE capable switch or it can be to where the EC-xx PoE device is powered from it's own transformer to then inject that power onto the Ethernet cable. Being "remote" for the EC-PoE device is to be remotely connected from the head end, at the camera's location.



When using the EC you will use the Extended Distance Port to connect the local and remote to eachother.

When using a standard network switch and want to use the PoE feature on the EC device plug your 48V power supply into the POE+/- terminals. Note: Please confirm you are using enough power to power your IP camera. EC-coax does not support PoE from the device only PoE switch (PoE pass-through).

If you camera requires a direct power source non-PoE and using a standard network switch, connect your power supply to the AC/DC+/- terminals.

With the EC you will generally set the 10/100 DIP switch to 100 (down), this applies to both the coax or UTP model.

With the EC-coax model LC (Local) have the button unpressed, dip switch down. For RM (Remote) have the button pressed in, dip switch up.
