Notes on SREL connection - SmartRelay, SmartRelay G2

To use a SmartRelay as a card reader in a third-party access control or time-and-attendance system, the hardware (cabling and signal emitter) and data formats must match those of the card reader precisely. This is the only way that the third-party system will be able to understand and evaluate data from transponders.

First of all, the SmartRelay reads the transponder data. If the transponder is authorised for use in the SmartRelay, these data are transmitted to the third-party system via the serial interface. You will receive detailed specifications for individual data formats from SimonsVoss Technologies GmbH.
