DESCRIPTION
Internal strap code derived from internal circuit
jumpers CJ1 and CJ2 located in the unit bezel
assembly.
software to identify the version of unit hardware: 0 =
Dual Axis with Altitude Preselect (--7xxx), 1 = Dual
Axis (--5xxx), 2 = Single Axis (--2xxx).
Strap code derived from open/ground discrete inputs
which represent the harness strap value for a
particular
STRAP_6 through STRAP_1 in the harness,
STRAP_6 represents the most significant bit and
STRAP_1 the least significant bit. A ground on the
input represents logic "one" and an open represents
a logic "zero". During preflight test, these inputs are
compared against the strap code defined in the
certification data stored in the configuration module.
