All about the RS485

The RS485 isn't used for communicating between the door station and monitor, must use the cat5 or cat6 cable using the RG45 connector/plug, or the two wire cable for the NT-2 wire series. The RS485 is used only to connect and monitor auxiliary devices such as RS485 capable devices, sensors, alarms, ect...

When it comes to actual speed of data transmission, across all RS485, data rates up to 10 Mbit/s or, at lower speeds, distances up to 1,200 m (4,000 ft).

RS-485 networks can achieve reliable data transmissions in electrically noisy environments. By considering the trade-off between data rate and cable length, you can design a system that achieves data rates in excess of 100Mbps over cable lengths of hundreds of meters, and without repeaters.

We will add a more comprehensive set of information for the RS485 enthusiasts...
