TM 5-6675-316-14
(4) Each data track character segment consists of 18 bits represented by
either transparent or non-transparent adjoining lines. The first six bits relate to
the strobe track, and each succeeding set of three bits relate to a character in one
of the four fonts. Since there are two tracks of width information, each character
has six data bits. The width codes per character represent five data bits (O to 31)
and a parity bit. The data bits will be translated in the photo unit to character
unit widths as
2-12
