Transparent Bridge
As an alternative to Modbus Bridge, Z-PASS can be configur ed to run as a “Transparent Bridge”. The big
difference between these two modalities is that, while the first works just with Modbus protocol, the
second could virtually applied to any serial protocol that can be transported over the TCP/IP stack.
As a Transparent Bridge, Z-PASS provides the following operating modes:
Remote Serial COM (with RFC 2217 support)
Serial Tunnel Point-to-Point on TCP
Serial Tunnel Point-to-Point on UDP
Serial Tunnel Point-to-Multipoint on UDP
Each mode will be fully described in a specific paragraph below.
