FLEX Control Terminal
Introduction
The FLEX Control Terminal is intended to be a simple MMI interface for other "projects" that, does not include
fx. LCD display / buttons, the idea that it can be attached to a RS485 port, and over that communication
interface send/receive commands to/from a remote device, so that it present the received data, and transmits
if fx. a button is pressed.
All my devices that have a RS485 bus uses a protocol, which handles node addresses, meaning that
devices has there own uniq address, that again means that the Flex Control Terminal, can be selected to interract
with different devices on a bus.
