2.5 Product overview
The Interface Box model 29122 is used for the serial communication between the ATEX Portable
Gas Analyzer 3650EX and a computer. The Interface Box unit changes TTL digital signals from the
instrument 3650EX to RS-232 compatible signals for computers. The Interface Box supplies
electricity to the 3650EX instead of the 3650EX's built-in lithium battery.
The Interface Box must be installed in a safe area without risk of explosion.
The Interface Box lets the user operate the WinLog97 PC customer program, change some settings
of the 3650EX, and download the recorded measurements.
