Rev 2.0 : X11CA-IM MASTER MODULE
1 OVERVIEW
The X11CA-IM Interface Module monitors alarm module activities. It also provides
special features, such as Slave Modbus RTU Protocol on Port (P2), time stamped
event archive, common trouble alarm, dual horn output, reflash output and system
diagnostic output. All outputs are generated in the form of an open collector
transistor and selectable Form C dry contact. The LEDs on the board indicate serial
communication and system status.

1.1 Definitions
RS-232 A point-to-point serial connection standard. The RS-232 standard
was designed for communication over short distances (up to 50
feet).
1.2 Revision History
Revision 1.0 ECO11217 : Page 1, Definition Section, RS-232 was revised to
remove the line, ‘and at relatively slow data rates, (up to 20 kbps).
However, in practice, these limits can be exceeded’

Rev 2.0 : X11CA-IM MASTER MODULE
2 X11-MF3 FIRMWARE
The firmware on the X11CA-IM scans each X11CA alarm module for the following
information.
Field contacts (A, B, C, D),
H1 (Horn1), H2 (Horn2) and CTA (Common Trouble Alarm),
Operation mode for each channel (IA, IB, IC, ID),
First Out indication for each channel (FA, FB, FC, FD)
The scanned information is then stored into the holding registers, starting at the address
00, in two byte format as shown below.
Hi byte FD FC FB FA ID IC IB IA
Low byte S H2 H1 CTA D C B A
The following list has the descriptions of each data bit.
Descriptions
A Status of the first input
B Status of the second input
C Status of the third input
D Status of the forth input
CTA Status of Common Trouble Alarm
H1 Status of the Horn1
H2 Status of the Horn2
S Communication status bit: 0=Successful, 1=Failed to communicate with
X11CA Alarm modules.
IA Operation mode of Channel A. If IA=0, CH A is Contact Input.
If IA=1, CH A is serial input.
IB Operation mode of Channel B. If IB=0, CH B is Contact Input.
If IB=1, CH B is serial input.
IC Operation mode of Channel C. If IC=0, CH C is Contact Input.
If IC=1, CH C is serial input.
ID Operation mode of Channel D. If ID=0, CH D is Contact Input.
If ID=1, CH D is serial input.
FA If FA=1, CH A is the First Out channel withi n the group.
FB If FB=1, CH B is the First Out channel within the group.
FC If FC=1, CH C is the First Out channel within the group.
FD If FD=1, CH D is the First Out channel within the group.

3 CABLES
The Port 2 is communication port to host device and can be either RS232 or
isolated RS485.
? The RS485 connection is a 5 pin screw terminal and the pin assignments are
marked on the cover.
? The RS232 connection is the 9 pin female connector and the pin assignments
are listed below.
