HN-2010 Repeater
HopNet Family of Products 800281Rev. B 26
Power
Power for the repeater is +7.5 to +24 VDC. The current consumption of the repeater
depends on the radio operating mode and the state of battery charge, but is typically
330 mA.
Battery backup is provided to maintain power during outages. Approximate
operating time from this battery is 2 hours. A trickle charge is maintained on the
battery whenever the unit is externally powered. Sealed lead acid cells are used in
the repeater because of their long-term reliability and charge storage characteristics.
However, the batteries will discharge if the unit is not operated for a period of time.
Voltage limiting circuits are in place at the connector to ensure that incoming voltage
does not 25 VDC. One-amp polyfuses are placed in series with the external
power supply and battery to avoid catastrophic current draw in case of an accidental
short. In addition, a low voltage lockout circuit is also included to shut off the unit
when the voltage-supplied drops lower than 5.5 volts at the connector.
Antenna Connectors
The external antenna connectors are located on the front panel and are female TNC
connectors
.
See the illustration below.
Proper placement of the external antenna is important since two modems inside the
HN-2010 will be operating simultaneously. Be sure to physically separate the
antennas from each other because the output transmission of one side of the repeater
may interfere with the reception of the other. Use a remote cable between the
repeater and each antenna, and space the antennas at least 2 meters apart.
