G. Serial communication

RS-232, RS-422, and RS-485 are all physical standards for serial communication:

- The bi-directional data communication has the advantage that it can produce “life

feedback”

- The data format, or protocol, that a controlled device is expecting will be described

in the unit's manual – it is different for every manufacturer and sometimes even every

model

- Serials settings: Depending on the controlled device the data will have to be send

out following a certain way, more in particular the speed at which it communicates

(baud rate), the error checking (parity), the number of data bits and the number of stop

bits. In addition, a given device may require hardware (RTS/CTS) or software

(XON/XOFF) handshaking, which controls the flow of data between two devices

-Cables: every serial controlled device has to be connected to a CRESTRON system

with a non-standard cable. This cable differs from unit to unit. The regular updated

CABLE DATABASE contains a lot of cable diagrams.
