2.2 AN-50e Terminal (Indoor Unit)
The front panel of the terminal includes a LAN interface and three groups of LED
indicators: system, Wireless, and Ethernet. The rear of the terminal includes the
power connections, an F-Type female connector for the IF cable, and a BNC
connector for the time signal (future release).
2.2.1 Mounting
The terminal can be freestanding on a flat surface, or mounted into a standard 19-
inch equipment rack (mounting brackets provided).
2.2.2 Power Supply
Power supply options include AC or DC supplies. Refer to the appendix for
specifications and DC terminal connections.
Grounding Connection
A ground connection terminal is located on the back of the AN-50e system.
Correct grounding is very important for safe operation of wireless equipment.
Refer to the installation section for additional information.
System Fuse
Removable fuses located at the rear of the terminal protect the system power
inputs.
Warning to service personnel :
Caution for all AC and DC models – Double pole/neutral fusing.
2.2.3 Time Synchronization Port
The AN-50e has one BNC input on the rear panel for time synchronization. This
port accepts a standard IRIG-B signal (1 pps) from a GPS satellite clock. This port
is currently disabled and may be enabled in a future software release.
2.2.4 Wireless Section
This section describes the wireless port and LEDs.
IF Port (Radio Control)
The terminal has a female F-type connector (rear of chassis) for interconnection
with the system radio.
The IF cable carries the following signals between the terminal and the radio:
- OFDM IF signal at 815 MHz
- Local Oscillator (LO) signal at 2.5 GHz
- 24 Volt DC voltage for the transceiver electronics
- Control signal between IDU and ODU
