RS232 serial line connection.
Connector pinout.
Plug-in part. 9-pin male SUB-D connector.
Cable characteristics.
Twisted-pair shielded cable should be used to minimize interference between cables, thus
preventing poor communication in long lengths.
Node connection.
The cable shield must be connected to the connector at both ends. It is recommended to
reference all the control and data signals to the same point (pin 5 GND), thus avoiding
reference points with different voltages because there could be voltage differences in long
lengths between the two ends of the cable.
Characteristic.
Type.
Shielded. Twisted-pair, with a minimum wire section of 0.14 mm².
Capacitance.
164 pF/m (50 pF/ft).
Maximum length.
At a baudrate of 19200 Bd, 15 m (50 ft) or a length equivalent to a capacitance
of 2500 pF.
