ECOUNT is a wireless software application that uses computers and hardwired or wireless RF technology to count target hits. It runs on a Windows 95/98/Me/2000/NT4.0/XP PC. The RF transmitter has a working range of well over 350+ feet. There can be either single or dual display's allowing one or two competitor's to compete. The transmitter comes with a normally open sensor and magnet. As a target is hit the sensor will close and transmit a hit. The transmitter can also be connect to a relay that performs open and close. To connect the transmitter to a relay you would need to remove the NO sensor and connect the two ends directly to a relay. If you are NT, 2000 or XP you must delete any printer driver associated with LPT1 or LPT2 depending on which port you use. Failure to do so will result in unpredictable results. eCOUNT comes with a database for teams and users. You can display and export competition data.
