Networking:
Your MCG-2 may be used as a stand alone unit, or in a network of
linked MCG-2’s. Networking allows more than one MCG-2 to be
controlled from a single PC computer, over a single RS232 link.
A MCG-2 network is much like a telephone party line, where each
subscriber may listen in but only one person is allowed to talk at any
one time. Because of this, each MCG-2 may be put to sleep or woke up
and in this way only one MCG-2 will talk at any one time.
Each MCG-2 in a network is assigned a unique ID number. (See “Set
