CAUTION:
1) Referring to "6. PARALLEL INTERFACE" and "7. SERIAL INTERFACE," check the pin configuration of
the interface connector and cable. Wrong wiring could cause trouble or malfunctioning to not only the unit
but also the host computer.
2) When disconnecting/reconnecting the interface cable, be sure to hold the connector. Pulling the cable itself
may snap the internal wires.
3) Connect the interface cable securely. Otherwise, communications may not be obtained due to a connection
failure.
