HN-210 and HN-210X Base/Remotes
Introduction
The HN-210 and HN-210X are NEMA 4X weatherproof versions of the HopNet
product line. The interface to the 210 and 210X allows the Host to communicate with
the Remote unit through an integrated 50 ft (15 meter) cable.
Design Features
The HN-210 Remote has an internally mounted 6 dBi patch antenna. The built-in
antenna of the HN-210 case greatly eases outdoor installation since no antenna
feedline cable or adapters are needed. The 6 dBi antenna gain increases the radiated
EIRP to +24 dBm and the effective receiver sensitivity to –99 dBm. The HN-210X has
a TNC connector for attaching an external antenna and a mounting plate that
accommodates both the HN-210X and any of the following external antennas:
Corner249
Corner2414
Omni249
Omni2412
The HN-210 and HN-210X remotes interface with the user’s hardware through an
interface adapter. The interface adpater supplies power and signal to the remote
unit. The interface to the remote unit is a standard RS-232 DB-9 serial interface.
Eight is the minimum number of pins necessary to convey all of the signals needed
to communicate with the modem inside the remote unit. The interface adapter also
supplies power to the remote unit thorough an AC to DC power adapter. See the
illustrations below.
