operation results in the display of a go signal. Failures are
indicated for the gunner linkage, the pilot linkage, and the
EIA. The logic circuits differ between the two EIAs and the
logic circuit cards are not interchangeable and have
different unit designators (A10 in the EIA for XM128 and
Al5 in the EIA for XM136). The electrical difference
Gunner helmet sight
between A10 and Al5 is in the resistor network used
during test of the linkages. Logic card Al5 also has separate

test inputs for the gunner and pilot linkages.
1-14. Extension Cable.
An extension cable is required between the aft end of
the gunner linkage assembly and the EIA (fig. 1-2). The
cable is secured to the overhead canopy supports and has a
mounting bracket at the forward end and a rectangular
cable connector at the aft end.
