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.
Tone Rejection: Greater than 36 dB rejection to tones more than +/- 3.5 percent
off frequency.
Tone Amplitude Difference: Must be less than 10 dB.
(Twist)
Tone Duration: 750 milliseconds minimum, 1.25 seconds maximum
Tone to Noise Ratio: -6 dB minimum.
Tones Decoded: 16 ARINC standard SELCAL tones, labeled A, B, C, D, E, F,
G, H, J, K, L, M, P, Q, R, S.
Code Selection Method: Jumper wires in the installation harness or ARINC compatible
SELCAL selector panel.
ARINC Interfaces: NON-INTERRUPT and INTERRUPT lines, turned on per
ARINC 714 for chime and external annunciators. Maximum
off voltage, 80 VDC. Maximum on current, 2 amps.
Annunciator Interfaces: Two or five outputs which connect to LIGHTS IN pin when
associated channel is decoded. Maximum off voltage, 80
VDC. Maximum on current, 2 amps.
External Resets: Two or five inputs, normally open. Closure to ground will
reset associated channel annunciation.
Self-Test: Grounding SELF-TEST pin on connector will cause unit to
perform complete end-to-end self-test. Unit checks for valid
decode code strapping upon self-test.
