Seattle, WA USA

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).

Two or five inputs, transformer coupled. Each input is

nominally 10,000 ohms input impedance.

0.1 VMS to 3.2 VMS

Normal operation with tones less than 0.3% off frequency.

Greater than 36 dB rejection to tones more than +/- 3.5 percent

off frequency.

Must be less than 10 dB.

750 milliseconds minimum, 1.25 seconds maximum

-6 dB minimum.

16 ARINC standard SELCAL tones, labeled A, B, C, D, E, F,

G, H, J, K, L, M, P, Q, R, S.

Jumper wires in the installation harness or ARINC compatible

SELCAL selector panel.

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.

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.

Two or five inputs, normally open. Closure to ground will

reset associated channel annunciation.

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.
