    CDA70 MODEM DESCRIPTION 2. Description of the CDA70 radio modem 2.1. General The CDA70 radio modem is a device for wireless data transmission. Communication between two radio modems is a simplex one and is carried out on a single frequency. Modems work in frequency band of 143 to 174 MHz (CDA70V) and 403 to 470 MHz (CDA70U).
  • Page 6: Modem Component

    CDA70 MODEM DESCRIPTION Modem component 2.3.2. The modem part converts digital bit flow from the microcomputer to the FFSK or GMSK analogue modulation, which is brought to the transmitter of the radio data module. And vice versa, it converts analogue signal from the receiver to digital bit flow to the microcomputer. The modem part is designed on the basis of a CML integrated circuit.

  • Page 37: Measuring Dsr Output Signal Level

    CIO DESCRIPTION Measuring DSR output signal level 3.3.3. On CDA70 side, DSR signals on individual user interfaces are output signals. They are not internally controlled. Individual signals are connected via 1k8 ohms resistors to the 12V supply voltage (the same voltage as at the supply connector of CDA70). Due to the loading of DSR output by a 100 ohm resistor to the earth, the supply voltage on the output drops to 2V.
