4.1 Serial Communications:
MJ1: (RS-232 / RS-485) Use for Cscape programming and
Application-Defined Communications.
MJ2: (RS-232 / RS-485) Use for Application-Defined
Communications.
As seen when looking at the side of the XL6 unit:
The DIP Switches are used for
termination of the RS-485 ports. The
XL6 is shipped un-terminated.
To terminate, select one of the DIP
Switches and configure it based upon
the option that is desired.
