The key components of the Q-Mux system are:
IDMs
– ID modules are placed remotely in the field and communicate over a pair of
wires (TBUSS) with a Q-Mux Node controller. The IDM’s are powered by the same
wires it uses to communicate. Many different types of ID modules are available with both
input and output capabilities. The Q-Mux system is designed so that as many 99 IDM’s
can be connected on the same pair of wires (TBUSS).
TBUSS
– The pair of wires extending from an Q-Node out to the field where the IDM’s
are remotely located. The TBUSS is low voltage and current limited. It both powers the
remote IDMs and is used to communicate with the IDMs.
Q-Node Controller - The Q-Node Controller creates the signals necessary to
communicate with the IDMs on a pair of ordinary wires.
Q-Mux Programmer – The Q-Mux Programmer is used to assign an ID number to each
of the IDM placed on a TBUSS.
Q-Mux Node Utility Software - Q-Mux Utility Software is a Q-Node diagnostic and
address PC utility. The software allows the user to test Q-Mux Nodes and Input or Output
devices connected to it from their computer and assign node addresses to the Q-Mux
Nodes.
Other items that are discussed are:
Style 3 – Term for a connection between the System 3505 and the Q-Nodes. This connection
is simply a pair of wires that connect the System 3505 to the Q-Nodes. The connection is
supervised at the System 3505, but a single break in the wires could interrupt communication
to the Q-Nodes.
Style 6 - Term for a connection between the System 3505 and the Q-Nodes. The System
3505 communicates with the Q-Nodes over two pairs of wires that forms a large loop. This is
an improved method of connecting the System 3505 to the Q-Nodes in that a single break
anywhere in the wires does not interrupt the communication to the System 3505. This
connection is also supervised and any break will be annunciated on the System 3505.
