FAQ:
Q: What is the difference between RS422 and RS485?
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’s the difference between DB9 and RS-232?
A: RS-232 is a signalling standard, and DB9 is a connector standard. Most cables that are intended to carry RS-232 signals, have DB9 connectors — but some RS-232 cables have different connectors, and some cables for other signals have DB9 connectors. The Empeg cable is suitable for RS-232 (and has DB9 connectors).
Q: What is RS422 protocol?
A: It uses a single-ended multi-drop cable for transmitting data. The data can be transmitted from one transmitter, but at the other end, there may be 10 receivers. RS 422 is eligible to transmit data by following full-duplex and half-duplex communication mode. More items…
Q: What is Rs 422?
A: RS-422 is a telecommunications standard for binary serial communications between devices. It is the protocol or specifications that must be followed to allow two devices that implement this standard to speak to each other. RS-422 is an updated version of the original serial protocol known as RS-232.
