Converts encoded badge information from Wiegand readers
to an ASCII string.
Encoded badge information is transmitted as an ASCII string.
The Reader's LED is activated by receiving a command string.
A command sequence also controls an on-board relay.
When connected to any Wiegand output reader, the encoded badge information is output as
a formatted ASCII string. The output of the CVT-2240 can then be captured by a
communications program running on a PC or printed directly on a serial printer. In
addition, commands can be sent to the CVT-2240 to control the reader's LED and activate
an auxiliary relay located on the Converter's circuit board.
Verifying encoded badge information.
Creating a database of existing badges.
Entering badge information into a program.
Testing badge or reader integrity.
Remote Control of Door strikes, MagLocks, Turnstiles, and Gate arms.
