2.3 Interface Specifications
The parallel interface sends 8 bits (one byte) of data at a time and is transistor-
transistor-logic (TTL) compatible.
The interface cable must be made of American Wire Gauge (AWG) No. 28 or larger. The
maximum length of the twisted-pair shielded cable must be 2.0 m (approximately 6.6
feet).
