5.4 Digital Outputs on Connector X4
There are 2 digital outputs available on terminal X4. 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.
