Radio data transmitter WZ FS 80-3

WZ FS 80-3

Radio transmitter for voice and data in the 70 cm band

The WZ FS 80-3 is a radio transmitter in OEM board design which can be used for data and voice transmission in the 70 cm band. Due to its very small and compact design and easy handling, it is perfect for the integration in data systems with high data rates across larger distances.

Data rates up to 9,600 bps are possible in connection with a GMSK modem, up to 4,800 bps in connection with an FFSK modem.

The radio transmitter meets the requirements of the German VDV (Association of German Transport Companies) guidelines and can be used for this type of application anytime.

The modern WZ FS device offers many functions.

Features

  • Setup via extended command interpreter using a terminal program.
  • 32 memory spaces; transmission channels and power rates can be set separately.
  • Selection of the memory spaces via hardware or software.
  • Automatic adjustment of the transmission power in case of interference or mismatches. This feature can be adjusted in the software.
  • Debounce time for hardware selection lines. The time can be adjusted in the software.
  • Automatic overtemperature protection. This feature can be adjusted in the software. Display for overtemperature (for example, an LED with series resistor can be installed at the user interface. For more information, please see chapter 7.3 Information on troubleshooting).
  • Display of device error conditions. The display time can be adjusted in the software (for example, an LED with series resistor can be installed at the user interface. For more information, please see chapter 7.3 Information on troubleshooting).
  • File download from the PC to the WZ FS device in order to setup parameters.
  • File upload from the WZ FS device to the PC in order to display the parameters in the terminal program.
  • File download from the PC to the WZ FS device in order to install new WZ FS firmware.
