HN-2010 Repeater

HN-2010 Outdoor Base/Remote Station
Introduction
The HopNet Repeater (HN-2010) provides extended range capability between two
HopNet networks. This repeater capability allows HopNet networks to be “daisy-
chained” in series to send and receive data from remote locations that would
otherwise be outside the coverage area of a single network.
If a remote unit is unable to communicate with the Base because of distance or
obstruction, you can install a repeater. Repeaters work by re-transmitting the data
from the outlying remote to the base and vice versa. The repeater will introduce a
small amount of transmission delay. However, as a dual modem repeater, the HN-
2010 does not halve the data throughput which is common in store -n- forward
repeaters.
Design Features
The HopNet Repeater consists of the following:
•
Two modems. One for communicating with out-of-range units. The other re-
transmits to the base.
•
A backup battery supply (with built-in charging circuitry)
All components of the repeater are located inside a rugged, NEMA 4X weatherproof,
aluminum enclosure. Connections into and out of the box have been kept to a
minimum to reduce the chances of industrial agents getting inside the unit. The
enclosure is weatherproof and will resist the normal grime associated with industrial
environments.
