RS485:

For terminate the RS485 line with a 120Ω resistor it is necessary to put ON dip 1, 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.
RS232:
The connection from RS232 socket to a serial port (example one from a personal computer) must be made with a
Null Modem cable (a serial cable where the pins 2 and 3 are crossed).
It is recommended that the RS232 cable not exceed 15 meters.
The device is provided with a D-sub connector type DE-9 Male (also called DB-9). The cable must use a DE-9
Female connector.
