Firmware Update; Technical Assistance - CTI 2500 Series Quick Start Installation Manual

Firmware Update

Prior to using the CTI Controller, you should verify that the controller firmware is current. The firmware
version number for the controller may be obtained by displaying Status Word 260 and Status Word 261 using
your programming software or by using your web browser to access the web server embedded in the CTI
2500 controller. You may determine the current firmware level by accessing the CTI web site -
http://www.controltechnology.com/support/software-revision/
If newer firmware is required, you may obtain it directly from the CTI web site -
www.controltechnology.com/downloads. The CTI 2500 Series Controller Installation and Operation Guide
includes a chapter that explains how to update your firmware.
