Configuring the Network
Guidelines for Installation
When installing your system, always consider the following points:
For systems with constant interference present, you may need to change the polarity
of the antenna system and reduce data streams. Groups of short data streams are more
reliable and have a better chance of success in the presence of interference than do
long data streams.
Systems installed in rural areas are least likely to encounter urban interference.
Multiple HopNet systems can operate in close proximity to each other but require a
unique network address.
Aiming the Antenna and Placing the Remote
Use the following guidelines for aiming the antenna and placing the Remote.
Do not place anything immediately in front of the antenna that could obstruct its
radiation pattern. Because the antenna in the HopNet Remote is inside the unit, the
antenna must have a clear line of sight.
Use the sticker on the HN-110 Remote unit to help you locate and aim the antenna.
The sticker indicates which direction the antenna is pointing.
Be sure the antenna end of the HN-110 Remote faces the Base or Repeater that it is
communicating with. Our tests have found that antenna placement is not critical as
long as the patch antenna is facing in the general direction of the other end of the link.
If possible, place the Remote unit at a higher elevation than the structures surrounding
it to increase range and link reliability. Since the Remote will operate with up to 100
feet of interconnect cable between it and the Host, you can mount the unit on top of a
building or other structure that will provide higher elevation.
Interconnect Cable
The HN-110 comes with a 6’ (2 meters) high quality interconnect cable. The cable
may be lengthened by adding an additional 50’ cable (part no.: CBLEXT50). The
maximum cable length that the HN-110 will support is 100’ (30 meters).
