Installation Considerations
Wire and Cable Recommendations: The ER1651U is designed for use with up to sixteen (16) Pairs
of Twisted Wire, compatible with all Category cabling (Cat3, Cat5, Cat5e and Cat6). The quality of
which must be consistent with any reasonably serviceable cable condition. That is free from damage
as in cuts, breaks, or cracks to the outer covering and insulated shielding which may compromise the
signal conductivity of the cable.
For more specific information regarding wire types, gauges, and proper installation techniques please
call Tech Support at 1-(800)528-4343 USA or (847)259-8900 (outside US).
Ethernet & PoE: The ER1651U is designed to receive up to 100Mbps (per transmitter) of Ethernet
data and transmit up to 1 Gigabit of aggregate LAN traffic. Additionally, the ER1651U provides per
port sourcing power to operate the transmitter (ET1551U). The transmitter, using the optional power
input can support both 15.4W (802.3af) and 25.5W (802.3at) power schemes at a maximum distance
of 1,600ft./500m. Before considering this solution be sure that the cable involved does not exceed
the recommended maximum lengths. If the cable length is indeterminate at the time of installation,
we recommend the use of a time domain reflectometer (TDR) or other method to determine length of
unknown cable distance estimates.
