CLX2

Manufacturer Part Number
CLX2
Description
19200 baud modem transceiver
Manufacturer
RADIOMETRIX [Radiometrix Ltd]
Datasheet
The CLX2s a 19,200baud half-duplex serial
radio modem module operating on licence-
exempt European 433.05-434.79MHz SRD
band. CLX2 is an intermediate level OEM
radio modem which is in between a raw FSK
radio module like BiM2G and a
sophisticated OEM radio modem like
RPM2A. It takes care of preamble, frame
synchronisation and error checking.

... With typical microcontrollers and UARTs, direct connection is possible. 5. The CLX2 provides a half duplex link, but provided no two devices attempt to transmit at one time then no further restrictions on data transmission need be made, as all transmit timing, valid data identification and datastream buffering is conducted by the unit. There is no 'transmit enable' pin ...
