Appendix C - Serial Communications Set-up
The LMP configurator port can be used for communication between the
processor and either a terminal or a computer.
Note
It is important that this is done first because it sets defaults and pa-
rameter limits in the other boxes.
RS232C is standard and compatible with either terminals or computers which
allows communications with a single processor only.
