11.2 Serial Tunnel Point-to-Point on TCP
The Serial Tunnel Point-to-Point allows to extend a serial connection between two serial devices that
support the same serial protocol by a TCP/UDP connection.
In TCP operating mode, one Z-PASS is defined as the “Master” and another Z-PASS is the “Slave”: the first is
a Tunnel Client, which receives data from the serial line and sends them to an outgoing TCP connection,
while the second is a Tunnel Server, which receives data from an incoming TCP connection and sends them
to the serial line; in this mode a “tunnel” is established between the two serial ports.
In configuration phase, on the Master it is necessary to set the Destination IP Address and the Destination
Port that defines the outgoing TCP connection; on the Slave, you have to set the Listen Port on which the
incoming TCP connection is accepted.
The tunnel can be established through the LAN (Ethernet) or through the WAN (Mobile Network), also
exploiting VPN connectivity.
WARNING!
In the Serial Tunnel Point-to-Point on TCP operating mode, just one connection is accepted for a given
serial port.
11.3 Serial Tunnel Point-to-Point on UDP
The Serial Tunnel Point-to-Point on UDP operating mode is much like that on TCP.
