1.2.1 Operating Altitude

Model SSD120-50M
Model SSD120-62M
Model SSD120-65M
Model SSD120-80M

1.2.2 Accuracy

Accuracy throughout operating temperature range -30° to +70°C.
-1000 to +42,000 feet ±50 feet.
+42,100 to maximum altitude ±75 feet.

1.2.3 Serial Port Data Resolution

The resolution of the serial port altitude data is selectable in 100
foot or 10 foot increments. The default resolution of the altitude
digitizer serial data is 100 feet. To enable 10 foot resolution
configure the SSD120-(XX)M via software see §4.4.

Model Number
All models.

1.2.5 Environmental

All Model SSD120-(XX)M series of altitude encoder/digitizer
have been designed and tested to meet the requirements of TSO-
C88a, in accordance with RTCA Document DO160b, dated July
1984 (specifics provided upon request).

1.2.6 Over Range

The SSD120-(XX)M series of altitude encoder/digitizer will not be
damaged when operated beyond its specified maximum altitude
and may be exposed to a pressure equivalent to 100,000 feet, or
over pressured to 18 psi max.
-1000 to +50,000 feet.
-1000 to +62,000 feet.
-1000 to +65,000 feet.
-1000 to +80,000 feet.
