5.6 Digital Outputs on Connector X4
There are 2 digital outputs available on terminal X4 (type LRU500i-BD none). The transistor connection,
collector and emitter, of the optocoupler output is galvanically isolated from the reader electronic and routed
to the outside at terminal X4 without internal additional circuitry. The output must therefore be supplied with
an external voltage. Each output is linked fixed with an antenna. Reading of a valid transponder on the
internal antenna will affect the digital output OPTO1-OUT, a valid reading on the external antenna will affect
the digital output OPTO2-OUT.
