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.
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 Installation and Operation Manual SPECIFICATIONS Model Number: CSD-714 Avtech Part Numbers: 1200008-000 (5 channel, standard self-test) 1200008-001 (2 channel, standard self-test) 1200008-002 (5 channel, auto-reset self-test) 1200008-003 (2 channel, auto-reset self-test) Certified to TSO: C59 Conforms to RTCA Spec: DO-93 as amended.
CSD-714 Installation and Operation Manual Mating Connector: ARINC 600 style, size 1 with blank cavity A, Middle insert Arrangement 01 (60 pins), Bottom insert Arrangement 03 (2 coax, 2 size 16 pins, 1 size 12 pin). Tone Inputs: Two or five inputs, transformer coupled. Each input is nominally 10,000 ohms input impedance. Input Tone Level: 0.1 VMS to 3.2 VMS Tone Frequency Tolerance: Normal operation with tones less than 0.3% off frequency.
CSD-714 Installation and Operation Manual Power-On Self Test: Unit checks for valid decode code strapping upon power-on and will latch all annunciators on if invalid. INSTALLATION The CSD-714 is intended for mounting in the radio equipment bay of an aircraft and due to its wide operating temperature range does not need to be in a temperature controlled environment. Although the CSD-714 is equipped to monitor two or five inputs depending on version, it is not necessary to use all channels.
CSD-714 Installation and Operation Manual There is no charge for a code assignment at this time. This code is assigned to the USER and does NOT transfer with the aircraft when it is sold. INSTALLATION TESTING The following tests should be performed to verify the installation in the airplane is operating properly: 1. Apply power to the unit and press the SELF-TEST button to initiate a SELF-TEST.
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). The SELCAL code is composed of four letters. For instance a code might be FJ-LQ. The order of the letters within a group of two is not critical, however it is customary to place them in alphabetical order.
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. Internally they are connected to 10 VDC through a 4700 ohm resistor and will source approximately 2 milliamps when grounded.
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. A 20 dB attenuator may be required to reduce the audio level as referenced at the beginning of this section. Do not use audio from cockpit volume controls as input to the CSD-714.
