Ethernet:
The RJ45 Ethernet connector is used for networking the base station via IP protocol, a PC can use
t
h
i
s connector to monitor and control the base station locally or remotely.
The Reciter supports the 10/100Mbs specification (defined by IEEE802.3u) and the MDI/MDI-X
auto crossover function which means either a straight though or crossover cable can be used to
connect the base station.
There are two LEDs embedded in the RJ45 Ethernet connector, the green LED indicates that the
Ethernet link is active; the yellow LED indicates TX/RX status between the base station and the
network.
RF
input:
The receiver RF input connector: 50ohm female, N type.
RF output:
The exciter RF output connector: 50ohm female SMA or Optional N type.
RS232 and external reference clock (optional)
The female D shell, 9-pin connector is an optional interface to the transceiver. RS232 and external
reference clock (EXT_REF) signals share this connector. The pins of the connector are described in
table 3.
Pin No. Description Specification
1 reserved for 1PPS Input
2 reserved for TxD (RS232) Output: +/-5V to +/-15V TTL logic
3 reserved for RxD(RS232) Input: +/-5V to +/-15V TTL logic
4 GND Ground
5 GND(EXT_REF) Ground
6 GND(1PPS) Ground
7 NC No connection on pin 7
8 GND(RS232) Ground
9 External reference clock Input, sine wave or TTL logic,
Minimum input: 1.5Vp-p

Programming and monitoring
Programming and monitoring is accomplished using the IP Commander Software. This software is
based on the Java platform and can be run under various operation systems on the host computer,
it provides a number of useful facilities for the configuration and monitoring of the base station.
The IP Commander software allows configuring of the base station (e.g. the channel frequency,
output power, signal path, etc.) without hardware alignment, it also provides a simple means of
calibrating the RF power, RSSI level, audio line levels. For more details of IP Commander software,
please refer the document: RFT Doc No. 0305917801 (IP Commander User Manual).
There are two interfaces which can be used for connecting a computer and the Reciter:
