This table shows the maximum recommended distances when a RS232 data transmission cable of low capacity is used.
It is also advisable to use a shielded type cable.
The communication used is a null modem type (without flow control). This kind of connection is the most used in RS232
links. Uses only 3 wires to stablish full duplex connections between devices.
