Connecting RS-232-C to a Protocol Converter
To use this communication protocol from a computer equipped with an
RS-232-C serial port you must connect a RS-232-C to RS-485 protocol con-
verter. A large choice of those converters can be found from the shelf. The
following one are very popular ones and are not a limiting list: ROLINE IC-
485S, ROLINE IC-485S1, Burr-Brown LDM485S. Refer to the protocol convert-
er's t o properly configure i t and check it's connection t o a RS-232-C
interface. The above figure gives the standard RS-232-C pin-out and inter-
connection.
Point-to-Point Four Wires Full Duplex
This is the mode for single computer to a single MM4006 controller in long
distance or noisy environment high speed communication. The following
figure shows the how to connect your computer, or protocol converter to
the MM4006 controller.
Multidrop Four Wires Full Duplex
This feature enables you to connect up to 31 MM4006 controllers to one
serial communication port. As a network, each MM4006 controller will have
its own address to identify the commands that are sent to it. The following
figure shows the how to connect your computer, or protocol converter to
several MM4006 controllers.
