ADEMCO 4100SM Serial Interface Module Installation and Setup Guide
GENERAL INFORMATION
The 4100SM Serial Interface Module can be used as any of
the following:
A direct-wire downloading device that is used in
conjunction with the Compass downloading software to
program compatible control panels without having to use
a modem or telephone line. This is done by either
connecting the 4100SM to the serial port of a PC or to a
GSM communicating unit.
An interface device that is used to connect a serial
printer or a PC using the Honeywell Navigator Reporter
software to control panels that feature event logging
with printer output capabilities.
An interface device that is used to connect a control
panel to 3rd party Home/Facility Automation hardware
and software.
The downloading function is applicable in UL listed
installations only when someone is present at the site while
the downloading. However, the 4100SM is UL Listed for
use as an interface to an event logging printer.
The 4100SM is packaged with everything that is needed to
connect the RS-232 serial port of most IBM-compatible fixed
or portable PCs to the control panel. This includes:
1.5-foot alligator clip leads (4)
4142TR voltage trigger cable (9 pos.)
10-foot DB25 male to DB25 male RS-232 serial cable
DB25 female to DB9 female adapter
Bracket and insulator
Important:
Check your control panel’s installation
instructions to verify that your software supports the
feature and any programming options that may need to be
set for proper operation. Also, verify that you have
downloading software that supports direct-wire
downloading for the control panel you are programming.
INSTALLATION AND OPERATION INSTRUCTIONS
Direct-Wire Downloading Connections to a PC
Direct-wire downloading can be accomplished either by
connecting the 4100SM to the serial port of a PC or to the
programmer port of an IP or GSM type module.
Connections to a PC
Direct-wire downloading connections are made to a header
on the control panel’s circuit board via the supplied 4142TR
voltage trigger cable.
As shown in Figures 1 and 2, terminals 3, 6, 7, and 8 on the
4100SM are used. The three colored terminals (red, blue,
and white) must be left uncut for direct-wire downloading
applications. Most IBM-compatible PCs have two RS-232
serial ports (COM1 and COM2).
You must decide which serial port you want to use, and then
determine which type of connector (DB25 female, DB25
male, DB9 male, or USB) is provided for that port.
Refer to the following table for instructions on how to
connect each type of PC connector.
Type of PC Connector
Connection Instructions
DB25 female connector Use the RS-232 cable to make
connections between the serial
module and the PC serial port.
DB25 male connector
Use the RS-232 cable and gender
changer (not supplied) to make
connections.
DB9 male connector
Use the RS-232 cable and
DB9/DB25 adapter to make
connections.
USB Port
Use a USB to serial converter to
make connections.
NULL MODEM NOTE:
The 4100SM requires that your
PC have a DTE pinout in order to communicate properly.
Check the documentation supplied with your PC to
determine if the connector for the serial port you have
chosen has a DTE pinout (meaning that your PC transmits
data on pin 2 and receives data on pin 3) or a DCE pinout
(meaning that your PC transmits data on pin 3 and receives
data on pin 2). If your PC connector has a DCE pinout, you
must attach a null modem adapter (not supplied) to the RS-
232 cable to ensure proper pin connections.
If you are not sure whether your serial port is DTE or DCE,
assume that it is DTE. If a problem occurs, refer to the "In
Case of Difficulty” section of this document.
