Each of the 4 coax and SFP+ connector is paired with a status LED and there is a system status
LED (see Table 1 and Table 2 describing the LED's behavior).
Each unit also has mount ears for an easy and secure installation on any flat surface.
4.2 Power supply
This device requires 24V power supply for proper function. The Host side of the extender is
compatible with PoCXP standard and therefore doesn't require external power supply, once the
Frame Grabber supports this feature too.
At the Device side, external power supply must be used. Please, refer to Electrical specification
section of this document for exact Power Supply requirements.
Below is shown the power supply connector of the KY_FEXT unit. An optional power supply or
user selectable must be connected to this on the device side extender box.
Connect the positive wire from the power supply to the "+" connector, connect the GND pin of
connector to the ground wire and the negative wire to the "-" connector, as seen in Figure 2.
