RS485:
To terminate the RS485 line with a 220Ω resistor, it is necessary to put dip 1 ON, like in figure.
The maximum length of the cable should be 1200m (4000 feet).
Here some codes of cables:
Belden: p/n 8132 - 2x 28AWG stranded twisted pairs conductor + foil shield + braid shield;
Belden p/n 82842 - 2x 24AWG stranded twisted pairs conductor + foil shield + braid shield;
Tasker: p/n C521 - 1x 24AWG twisted pair conductor + foil shield + braid shield;
Tasker: p/n C522 - 2x 24AWG twisted pairs conductor + foil shield + braid shield.
