CSD-714 Installation and Operation Manual DESCRIPTION The CSD-714 SELCAL DECODER is a rack mounted, 16 tone decoder for the ICAO and ARINC standard SELCAL system, as defined in RTCA paper DO-93. It is available in both two channel (-001, -003) and five channel (-000, -002) versions. It has independent inputs for up to five radios, depending on version, to drive up to five decoder channels. -
Page 8: Operation
CSD-714 Installation and Operation Manual OPERATION Pilot operation of the CSD-714 is limited to resetting it after a call and performing a self-test. Normal Operation There are several installation options concerning how the annunciator lamps and audio annunciation work, as well as how the unit is reset after a call. The lamps may be connected to either be on steady or to flash when a call is received, and the audio annunciator may either ring once, ring repeatedly, or not at all. -

CSD-714. In this case, a 10 to 1 voltage divider (20 dB of attenuation) should be used in the audio input to the decoder. Avtech provides a in line attenuator under the part number 1200009-000 or one may be fabricated locally using Figure 4 as a guide. -
Page 12: Installation Testing
SELCAL decode should be received on all annunciators simultaneously. Using a ground test set such as the Avtech CTS-700 SELCAL/ATSCALL Ramp Test Set, select the frequency for test on one of the communication transceivers to which the CSD-714 is connected. -
Page 13: Notes For Installation Figures
CSD-714 Installation and Operation Manual NOTES FOR INSTALLATION FIGURES Note 1 - DECODE PROGRAMMING Programming the CSD-714 to respond to a selective call is done by connecting the code selection pins on the rear connector to the CODE SELECT RETURN pin on the rear connector (Pin MP9B). - Page 14 CSD-714 Installation and Operation Manual If manual reset is desired, they may all be tied together and grounded through a normally open, momentary contact switch. The SELF-TEST input (Pin MP3D) is activated by grounding it momentarily. All of these inputs are considered grounded when the voltage on the pin is less than 3.5 volts and are open when it is above 8 volts.
- Page 15 CSD-714 Installation and Operation Manual If the squelched audio output of the VHF is used, care must be taken to keep the audio input to the CSD-714 within rating. The frequency response of the output must be such that the difference in output level at any two frequencies between 300 and 1500 Hz is less than 3 dB.
