  • Programmable within 1Hz over a 300 Hz to 3200 Hz band
  • Can be programmed to operate as an FSK receiver/amplifier
  • RS-232 solid state or relay output

The RFL® 98 TMX Programmable Telemetry Transmitter & RFL® 98 TMR Programmable Telemetry Receiver

  • Designed for high accuracy transmission of analog information as SCADA backup
  • Occupies a narrow voice frequency band (50 Hz to 85 Hz)
  • Transmission accuracy is better than .1% over a temperature range of -30 °C to +70°F
  • Response time is less than 1 second. Input/output levels up to 10 Vrms or 50 mA
  • CADA backup
  • Occupies a narrow voice frequency band (50 Hz to 85 Hz)

9850 TX Description

The RFL® 9850 TX (Fig. 1) is a fully-programmable FSK tone transmitter. It can be programmed to operate on any standard center frequency from 300 Hz to 3200 Hz, with frequency shifts up to 300 Hz and at speeds up to 600 baud (2F operation only). The RFL® 9850 TX uses Digital Signal Processing (DSP) techniques to replace the discrete oscillators, modulators, and filters normally used in FSK transmitters.

The RFL® 9850 TX's operating characteristics can be changed by using the hand-held RFL® 9800 Programmer to modify the software. This means its operating characteristics cannot be modified by unauthorized personnel.
