Signal Functions
This section describes the function of each interface signal in detail. All input and out-
put signals are TTL compatible. Unless otherwise noted, the input signal levels are:
Low = 0 to 1.0 volts
High = 2.0 to 5.0 volts
And the output signal levels are:
Low = 0 to 0.5 volts
High = 3.0 to 5.0 volts
All input and output signals are considered to be a logic 1 for a high voltage level
unless the signal name is followed by an asterisk (*), in which case the signal is
considered to be a low voltage level.
