Due to the tuning limitations of hardware filters within an ODU, different ODU pairs will be
required within any particular frequency band. Given the large amount of spectrum within most
frequency bands, it is required to create smaller ranges as Sub-Bands. ODUs are tunable within
each of the sub-band. It is important to note that ODU pairs are made up with a Hi (High) unit and
a Lo (Low) unit. The Hi unit transmits on the higher channel and receives on the lower, while the
Lo unit transmits on the low channel and receives on the higher.

Accessories
For perfect installation, it is always recommended to use the following parts and accessories. You
can use any other accessories, not approved by the manufacturer or distributor, at your own risk.

Power Supply
The recommended power supply is 120W, regulated switching PS-230/48, power supply with
-48VDC and 2.5A output. From one switching power supply PS-230/48, it is recommended to
power only one side of the GX800 link, that means 1Power Supply x IDU + 1Power Supply x
ODU. When you connect other devices, it may cause power supply overload to the entire GX800
link.

IF Cable
To connect an IDU and an ODU, we recommend you to use low-loss 50 Ohm coaxial cable
designed for outdoor installation. For a distance greater than 50 meters, it is recommended to
ground the cable every 50 meters.

IF Cabling between ODU and IDU must be terminated with N-Male coaxial connections at each
end. Proxim provides 25, 50, 100foot lengths. Custom cables can be made but should be tested
for shorts and overall performance prior to installation.

Surge Protectors
Whenever the coaxial cable enters the building, always install a RF Surge Protector, which
greatly eliminates the risk of high power surge damage.
