7.2 Download Procedure
The Model 240-N4X Gas Detection Alarm System has very capable features in the area of data logging and
event reporting. Continuous data for TWA and Peak readings are stored at 1-hour increments in permanent
memory for retrieval. All Event Records are stored only as they occur. The duration of the recorded
storage is 1 month for the TWA readings, Peak readings, and Event Records.
This data can be downloaded to an external PC. The downloaded data can be exported into a Microsoft
Excel spreadsheet for graphing purposes. The procedure requires a computer with windows Hyper
Terminal, a serial port, and Detcon connections cable part number 980-26117. If the computer does not
have a serial port, a USB to serial adapter will also be required. USB to serial adapters may be purchased
from many retail electronics stores.
NOTE: The download feature will only work with the following X40 controller hardware. This number is
printed in white on the back of the controller PCB. The controller firmware must be a version that supports
this feature. The controller firmware revision can be checked by cycling power to the controller and
observing the LCD display.
