The PC connections require standard pin-to-pin (i.e. not crossover) serial cables. For correct operation, the
connection cables must be no longer than 20 m.
Ports 2 and 3 use only the Tx, Rx and GND signals for the PC connection, while Port 1 also supports the DTR signal
(Data Terminal Ready) used for modem connection. For communication purposes, the port speed must be similar.
