Direct Wire Downloading
General
The 4120XM can be downloaded at the office or installation site without using a
modem or telephone line by using 4130PC Downloading Software and a 41 OOSM
Serial Module.
The installer simply connects
the Downloading PC’s serial port to the control via
the 4100SM, thereby reducing downloading equipment cost while retaining the
user-friendly benefits of using downloader software for in-office or on-site
programming and troubleshooting.
The direct wire downloading connection is to be temporary, and is not part of the
permanent installation.
Direct wire downloading is meant as a tool for the
installer during the installation process.

below. The required connections from the 4100SM to the Downloader PC are
shown in Diagrams 2, 3, and 4 in the 41 OOSM Installation Instructions; the
procedure for direct wire downloading is also contained in that manual.
