OnLine 400 software is designed to perform testing while the Intoxilyzer 400PA is tethered via cable to a PC. The PC then controls the testing process, prompting the operator through each step. It provides a printout of the test results to any PC network printer, and stores the data in a searchable database on the PC. This database allows the assignment of identification numbers to each subject so that multiple tests of the same subject can be tracked over time. OnLine 400 can be configured by the end user to store and/or print various types of information about the subject providing the breath test. Note: requires special cable to connect instrument to PC/laptop.
