FAQ:

Q: What is the difference between RS485 and RS422?

A: The RS485 Standard is similar to the RS422 standard upon which it is based. The main difference is that up to 32 transmitter receiver pairs may be present on the line at one time. A 120 Ohm resistor should be used to terminate either end of the main line.

Q: What is a RS485 communication network?

A: What is an RS485 Communication Network? RS485 is a two wire data communication system where both wires are considered the carrier of the signals. As such, there is no ground/return. Two, three, four, up to dozens of devices can be connected to the same pair of RS485 wires.

Q: What is a RS485 connection?

A: RS-485 is a multipoint communications standard set by the Electronics Industry Alliance ( EIA ) and Telecommunications Industry Association (TIA). RS-485 supports several connection types, including DB-9 and DB-37.
