Positive Supply Voltage: Nominally +15V.
Digital Ground: 0V, ground return.
Status Output: HI during integrate and deintegrate until data is latched. LO when analog section
is in auto-zero configuration.
Polarity: Three-state output. HI for positive input.
Over Range: Three-state output.
Most Significant Bit (MSB).
DATA Bits: Three-state outputs. See Table 3 for format of ENABLES and bytes. HIGH = true.
