Wiring the RS-485 XNET Network
in Style 4 and Style 7 (MXL)
RS-485 NETWORK
The RS-485 MNET, XNET and HNET networks connect
to the D2300CPS on the terminal block with the mark-
ings +DATA (1) and -DATA(2).
Terminals 3 and 4 are
not used.
For Style 4 networks one D2300CPS is
needed at each Fiber Optic drop. For Style 7 networks
two D2300CPS modules are needed at each drop.End
of line devices are required on each RS-485 pair in the
system. Install them at the extreme ends of each pair.
Refer to Figures 7 and 8 (MXL) Figure 9 (FireFinder
XLS/Desigo Fire Safety Modular/Cerberus PRO
Modular) and Figure 10 (HUB-4 FSI) for wiring instruc-
tions and ratings for both Style 4 and Style 7.
NOTE:
Positive and negative ground fault detected
when terminals shorted to earth.
FIBER CONNECTIONS
The D2300CPS can function as both a
repeater
and an
end point
unit.
When used as an end point,
connect
to the fiber connectors labeled
A
. Make no connec-
tion to the
B
connectors.
In the repeater mode,
use
both pairs of connectors,
A
and
B
.
Two Fiber Optic cables are required between each pair
of D2300CPS modules. Use a high quality duplex Fiber
Optic cable containing either 50/125 or 62.5/125 fiber.
Duplex fiber optic cable has two cables in a single
shield similar to electrical
zip cord
. Use ST style fiber
connectors.
Please contact the fiber manufacturer
regarding instructions for terminating the fiber.
When installing the fiber pairs, each fiber must
connect between the transmit data (DATA XTMR) on
one D2300CPS and the receive data line (DATA
REC) on the other D2300CPS.
The D2300CPS fiber connection is classified as Style
DCLB and Style DCLA per ULC-527.
INDICATORS
The D2300CPS has five LED indicators for Power
and Status.
The LEDs are located on the side of the module with
the Fiber Optic connectors. The
Power
LED is green
and lights whenever there is 24 VDC. Both channels
A
and
B
have a yellow and green LED. The green LED
indicates that the D2300CPS is transmitting data on that
channel. The yellow LED lights when data is received.
