Outputs
The NVITE reader has 2 digital outputs. The function of the digital outputs is dependent upon the installed firmware
version. See description below.
STANDARD firmware
The outputs are used for Wiegand or Magstripe communication. See respectively chapters 3.2.3 and 3.2.4.
OSDP firmware
The outputs are general purpose outputs. The outputs are open-collector and can be used to activate an external relay.
Please ensure to install a flyback diode across the relay inductor to avoid voltage spikes.
Use the OSDP_OUT command to control the output state. The outputs allow for direct activation and deactivation plus
timed operation (OSDP output control compliance level 3). The permanent command is volatile (does not transcend
power cycles).
When the status of an output changes the reader will send an output status change report message OSDP_OSTATR.
