Primary/secondary interface and I/O connections
The VB34 reader has a 25-pin Sub-D connector for connection to computer, voltage
supply and input/output signals.
The fieldbus models (Ethernet, DeviceNet and Profibus) of the VB34 are equipped
with a 26-pin connector instead of the 25-pin connector.
The connection layout of this connector is shown in the following table:
