MODEL 5052RD-K : Receiver/Decoder
The Model 5052RD-K Receiver/Decoder receives ALERT2 radio data transmissions from remote sites and provides
a TCP/IP data output for the base station computer. The Receiver and Decoder are combined in a single desktop enclosure.
Rack mount brackets are included.
The Receiver/Decoder enclosure should be located near the antenna tower to reduce the length of the RF transmission
line and the associated RF signal loss. It is recommended that a lightning arrestor with ground lug (optional) be placed between
the ALERT2 receiver back panel BNC connector and the antenna to protect against lightning damage.
Two LEDs on the front panel show when radio signals are received (BIT SYNC) and decoded (FRAME SYNC).
ALERT2 decoder data output is through the back panel RJ45 network or serial connector.
The ALERT2 decoder supports multiple server and client TCP/IP network connections from base station computers.
It supports the ALERT2 Decoder ASCII and Binary formats.
The Receiver and Decoder are powered by a fused 12Vdc power input from a 5030-PS power supply (optional) or 5081-18
12 Vdc 18 AmpHr battery (optional) with 5030-8 battery charger (optional). It is recommended that the power supply be connected to a
UPS (Uninterruptible Power Supply) to prevent loss of data during power outages. A power LED on the front panel is on when power is connected.
The power input fuse is mounted on the back panel.
