APPENDIX G: PROGRAMMING USING RS232
COMMUNICATION
G.1 INTRODUCTION
The RS-232 communication feature allows the ACS to be easily programmed to your installation
requirements using a listing of entry commands.
The RS-232 port located in the wiring compartment area of the ACS can be used to program the
ACS using a laptop computer or other suitable terminal. Connection to a laptop or other terminal
device is made by wiring to the RXD, TXD and GND connections (see paragraph 2.9 and
Figure 2-12 for pinout information when wiring from a DB9 connector). Communication can be
accomplished using any “Dumb Terminal” emulation, such as “PuTTY” which is not included
with Microsoft Windows, but can be downloaded for free on the internet. Source and instructions
for using Putty are provided here:
G.2 AQUIRING THE PuTTY APPLICATION
Download the putty.exe program to your desktop from:
www.chiark.greenend.org.uk/~sgtatham/putty/download.html
You can use PuTTY to logon to remote computers as well as run a single command on a
remote server. PuTTY does not need to be installed, so just clicking the downloaded executable
will start it.
G.2.1 Logging on to a Remote Machine Using PuTTY
To use PuTTY to logon to a remote machine, bring up the PuTTY application by double-clicking
its icon. You will see the main window as shown in left image of Figure 9-1.
