☞ The DTR, DSR and DCD signal lines (not shown) of the
C32061T/C32065T are internally shorted by design to meet certain
software requirements.
The RS-422 transmission distance can reach as long as 4000ft. The connection box
needs an external power adapter to supply 5V DC power. Either 110V or 220V AC
power adapter is selectable.
