The Multiplexer (Figure 17.1), used only in IS
3200 and BR 4200 Systems, decodes and relays
information from up to 8 Receivers to GDPs and
PCs with the Accutech Software.
The Multiplexer comes inside a Controller case;
this case can accommodate up to 2 Multiplexer
boards (16 Receivers).

Temperature
A Multiplexer operates best in an ambient
temperature between 35 and 90 degrees
Fahrenheit. Operation outside of this range may
cause unexpected or undesirable results,
including premature failure.
Weight
The Multiplexer (with the Controller enclosure
and the maximum 2 Multiplexer contained
within) weighs approximately 10 U.S. pounds.
Positioning the Multiplexer
The Multiplexer can be located above the drop
ceiling or remotely in a utility closet. However,
since Accutech Systems use RS232 cable to
connect from the Multiplexer to the PC (
at a 19/2
baud rate
), 50 feet is the recommended maximum
distance from the PC to Multiplexer Board 1
with out any special cabling or converters.
Consult your Accutech Representative for
special cases.
Mounting the Multiplexer
Multiplexers (up to 2) are housed in a Controller
enclosure. Use hardware appropriate for the
weight, size, and mounting surface. See Chapter
3 for case mounting instructions.
