1.0 Introduction
1.1
Description
Use the D8125MUX Multiplex Bus Interface Module
to connect multiplex points to the zonex bus on the
following Bosch Security Systems control panels:
D9412GV2, D7412GV2, D7212GV2, D9412G,
D7412G, D7212G, D9412, D7412, D7212, D9112,
and D9124 with version 5.22 or greater firmware.
Install the D8125MUX on Zonex 1 and Zonex 2
(D9412GV2, D9412G, D9412, and D9112 only). The
multiplex bus interface supports two independent
multiplex buses; therefore, a fault on one multiplex
bus does not prevent the other from operating
normally.
The D8125MUX scans the multiplex points connected
to it and reports the points' status to the control panel.
Point index programming then determines if the
control panel initiates an action (for example, alarm
response, trouble response, and so on).
Also available on the D8125MUX are auxiliary power
terminals labeled Power A (+,-), Power B (+,-) that
support remote devices requiring an uninterrupted
source of power.
D8125MUX is a Class B (Style 4) signaling line
circuit.
For additional D8125MUX installation information,
refer to the D9412GV2/D7412GV2 Approved
Applications Compliance Guide (P/N: F01U003639).
1.2
Programming
The D8125MUX is programmed using the D5060
Multiplex Point Programmer. The D5060 connects to
the D8125MUX PROG PORT located next to the
POWER A+ terminal. Individual point addresses and
point types are then programmed into the D8125MUX
EEPROM. In addition, the programmer must also
program each multiplex point that is connected to the
system, unless the point is equipped with
programming DIP switches. Reset pins are provided
(located above Zonex Bus Out terminal) to clear the
D8125MUX of all programmed points.
Refer to Section 3.2 Programming on page 6 for
programming information.
