TX8000

Synthesised Radio Modules TX8000/RX8000 Features • • • • No operating licence required. 32 Selectable RF Channels. Range 10-20km line of sight 1-3km in buildings RF frequency range: 400.00 MHz to 490.00 MHz 860.00 MHz to 930.00 MHz In 1.3MHz bands RF power output 5mW to 500mW Data rates: up to 10Kpbs TX8000 transmitter power 7.5 at 270mA RX8000 receiver power 5V at 35mA Approvals: ETSI 300-220, MPT1329 Size 36mm by 51mm by 14.5mm • • • • • • Description The synthesised TX8000 Transmitter and RX8000 Receiver can be set to one of 32 switch selectable RF frequencies. The modules can transmit data at 10Kbps for a distance of up to 20km line of sight and 1-3km in buildings. The radios are ideal for general telemetry applications. The TX8000 will transmit analogue data such as FSK, FFSK, GMSK and PWM from its analogue input or accept direct TTL digital data from its digital input. The RX8000 will receive analogue and digital data and present it to its analogue and digital outputs in the same format as it was transmitted. The units conform to ETSI 300-220 and ETSI 300-683.

Therefore the pins are numbered 1 to 7 RF FREQUENCY An example of how the RF Frequency is set using the Programming Pins is shown below. The frequency band can be factory set in the range 400.00MHz to 490.00MHz and 860.00MHz to 930.00MHz at 12.5KHz or 25KHz spacing in bands of 1.3MHz.
