TAS Valid Output
This output is provided as a primary indicator of valid system operation. This
output is driven to the valid state during normal operation. The TAS Valid dis-
crete will go invalid during power up self tests and operator commanded self
tests.
VALID = GROUND ( < 10 ohms to ground)
INVALID = OPEN
J10-25 TAS_VALID*

Visual Annunciate Traffic (Lamp Output)
The "Visual Annuciator Traffic" output is activated whenever a traffic advisory
is issued. This output will remain in the activated state for the duration of the
advisory unless cancelled or inhibited.
ACTIVE = GROUND ( < 10 ohms to ground), VOLTAGE 0 to +3.5 VDC.
INACTIVE = OPEN
Current Capability = 200 milliamps., when activated.
Voltage Capability = +36 VDC, when not activated.
J10-24 VIS_ANNUN_TRAFFIC*
3.1.10
Synthesized Voice output
KMH 820/KTA 810 will supply low level audio signals of up to 100 milliwatts at
1000 Hz into a 600 ohm audio distribution system. The outputs are on pins
"PH_HI" and "PH_LO".
J 10-20 = PH_HI
J 10-21 = PH_ LO
The power output will be adjustable based on the audio level inputs.
The TAS messages available for output are as follows:
1. "TAS System Test OK"
2. "TAS System Test Fail"
3. "Traffic, Traffic"
4. "Traffic"
