The "loader" service mode will be activated after holding the RESET button for at least 10
seconds. The periodically changing red-green glow of LED2 indicates that the E-502 is in the
bootloader mode.
2.5. Serial number. E-502 version number. Module
identification in a multi-module configuration.
The unique eight-digit product serial number (on the label on the bottom of the case) serves to
identify the module instance within its life circle. E-502 serial number is program-available.
2.6. E-502 application as a part of user programs
LLC "L-Card" supports integration of its modules in the user systems. But when E-502 is
included in any system, the system developer must mention in the documentation for his system the
E-502 module of the "L-Card" production, as the component part (the completing unit).
2.7. Software installation
To install the necessary drivers and libraries for Windows OS, you must download and run the
installer "L-Card L502 / E502 SDK" http://www.lcard.ru/download/lpcie_setup.exe .
For information on installing the driver and libraries under Linux OS, see
http://en.lcard.ru/download/x502api.pdf .
2.8. Ethernet interface configuration
To work with E-502 module via Ethernet, it is required to make settings and resolution of this
interface in the program "L-Card Measurement Studio" ( https://bitbucket.org/lcard/lqmeasstudio/ ),
connecting the module via USB. If Ethernet interface is not permitted, the E-502 module will not
respond to the connection of Ethernet cable (both LEDs
Link and Activity on the LAN connector
will be turned off).
