TXR-2450-RS485 Spread Spectrum Transceiver
OVERVIEW
The TXR-2450-RS485 is a hyper performance microwave radio data transceiver employing state-of-the-art
spread spectrum microwave communication techniques. With a permissible data rate of between 250Kbps
and 1Mbps it is an ideal candidate for constructing high speed wire free data networks for applications as di-
verse as real time industrial processing and monitoring through to WANs
Operating on the near globally accepted 2.450GHz microwave communications band, the TXR-2450-RS485
is designed for easy implementation by OEM’s and end users. Connection to the data interface is via a
RS485 serial port with TX and RX flow control lines.

In application each receiving module within range will receive the mes-
sages sent from the transmitting module. The user equipment must
provide a means for addressing the data so that the correct receiving
equipment can identify messages intended for reception. Network op-
eration can then be achieved by a suitable user protocol.
The TXR-2450-RS485 is supplied with either one or two dipole anten-
nas which are connected to the SMA jacks on the top of the unit. Each
of these antennas may be used for transmit or receive.
The TXR-2450-RS485 is split into two sections. The RF section con-
tains all high frequency RF signal processing and analogue data re-
covery circuits. The control section contains power supply, interface,
microcontroller and logic circuits.
The processor/controller handles various functions of the RF section
including Tx/Rx switching in response to data sent to the SSRT. It can
also select a power down mode (if enabled) when the data input/output
stays inactive for a set period. The processor reads preset switches to
determine operating channel and power saving enable. The processor
displays various status conditions such as data flow on its status
LEDs. The RS485 data input/output interface provides the link to the
user's equipment.
