Connecting Communications
One of the features that make the MicroLYNX a unique product is its dual
COMM ports. This allows for simultaneous use of both the RS-232 and the RS-
485 interface. This is especially useful in party mode where several MicroLYNX
nodes are networked in a system. This section will illustrate connecting
your MicroLYNX to a communications host, typically a PC, using a
single MicroLYNX and either the RS-232 interface or the RS-485
interface. For instructions on connecting communications to multiple
MicroLYNX Systems see the product manual.

The following tools and equipment are required to connect communi-
cations to your MicroLYNX System:
IMS communications cable part# MX-CC100-00 or equivalent
(if 10 pin header version of the MicroLYNX is used).
Communications cable (if 7 pin terminal version of the
MicroLYNX is used).
A free COM port on a PC.

The following diagram and table illustrate the connection of both the RS-232 and
the RS-485 interface to the MicroLYNX.

You can only use the
RS-232 interface if
your MicroLYNX is within
50 feet of the Host PC,
otherwise you must
use the RS-485 interface!
