8.0 DESCRIPTION OF FUNCTIONS 
In order to use a Smart Relay 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 SimonsVoss transponders. 
First of all, the transponder data are read by the Smart Relay. If the transponder is 
authorised for use in the Smart Relay, these data are transmitted to the third-party 
system via the serial interface. You will receive detailed specifications for individual 
data formats from SimonsVoss Product Management. 
The right reader type is selected in the Smart Relay configuration in the SimonsVoss 
software, version 1.40 and higher. The connections for the different reader variants 
are listed below.
