Using External Power Supply at Receiver Only
This section looks at the scenario where an external power supply (such as the POWER-60W or POWER-110W power
supply) is connected to the receiver.
Note: In this case, the transmitter must be powered separately as the receiver cannot power the transmitter. This can be
through either a PoE-enabled switch of at least a 802.3af class 2 compatible port (providing up to 6.49W) or the
POWER-60W external power supply.
Table 4 provides guidance as to the maximum distance between the transmitter and receiver when the 1-port receiver
(POEXRX1) is powered by a 60 W external power supply (such as POWER-60W) or the 4-port receiver (POEXRX4) is
powered by a 110 W external power supply (such as POWER-110W).
● Note that in this case, the 1-port receiver is using a 60 W supply and the 4-port receiver is using
a 110 W supply and they both have the same available power per port
● The "Max Wattage at PD" refers to how much power is available at the Powered Device (PD),
per port of the receiver
● The amount of power needed is dependent on the requirements of the Powered Device (such as
a security camera)
● The "TX1 – RX1 Cable Distance ft." refers to how far the transmitter and receiver can be
separated from each other with either 23 AWG cable or 24 AWG cable; as the receiver has
its own power, in all cases this is 2,000 feet (610 meters)
● Panduit recommends 23 AWG cable as it provides greater distance
● In all cases, we recommend no more than 50 feet (15 meters) from the transmitter and receiver
and the corresponding devices they are connected to
As can be seen from the table, in all cases since the receiver has its own power supply, the distance between the transmitter
and receiver is 2,000 feet.

(assuming 55VDC output) or a 4-port (POEXRX4) Receiver Box powered by a 110 W External Power Supply (such as POWER-110W).
A PoE Switch or additional external power supply (such as POWER-60W) is attached to the Transmitter Box (POEXTX1).
