2 Brief Description of DELTA OP
&RPPXQLFDWLRQV 3RUWV
The '(/7$ 23 panel has 3 communications ports for integrating the panel
with other network equipment. The communications ports support several
protocols, which can be selected by configuring the panel or by using plug-in
circuit cards.
The COM1 and COM2 communications ports — see Figure 2 — are 9-pin D-
Sub male ports principally intended for communication with computers,
printers, modems and other external units by using the standard 56 3RLQW WR
3RLQW serial bus.
The COM1 and COM2 ports can also be configured to support the '56
0DVWHU6ODYH¶ serial bus for communications with other network equipment on
the RS485 bus.
The '(/7$ 1HW communications port is based on the use of ".LW IRU 23 '$
H%XV &RPPXQLFDWLRQ %RDUG" — a circuit card to be plugged on the '(/7$ 23
main card.
Terminal block connections CN1-7.8 on '(/7$ 23 are to be used for
communications via a IUHH WRSRORJ\ PXOWLPDVWHU H%XV for connecting to other
modules and fire alarm systems in the '(/7$ and ANX95 families.
'(/7$ 23 must then use the plug-in ".LW IRU 23 '$ H%XV &RPPXQLFDWLRQ
%RDUG"
You can find more information in the folder, 'Installation Guide for .LW IRU 23
'$ H%XV &RPPXQLFDWLRQ %RDUG, which accompanies kit.
