The SDD can be easily installed by running the installer program available at the following link:

NOTE:
- when Z-PASS is working in “Switch” mode, the IP Address shown by the SDD is the same regardless of the
Ethernet port which the PC running the SDD is connected to;
- when Z-PASS is working in “LAN/WAN” mode, the IP Address shown by the SDD is the LAN IP Address
when the PC is connected to the LAN port, the WAN IP Address when the PC is connected to the WAN port;
moreover, the network configuration parameter changes apply to the relevant port.
9 Ethernet Mode (Z-PASS1-R01/Z-PASS2-R01/Z-PASS1-IO/Z-PASS2-IO)
In Z-PASS1-R01/Z-PASS2-R01/Z-PASS1-IO/Z-PASS2-IO products, the two available Ethernet ports can be
configured as two fully separated network interfaces (“LAN” and “WAN”) or, as in the older versions, they
can work as ports of an Ethernet switch; the user can choose between the “LAN/WAN” mode and the
“Switch” mode, by means of a new configuration parameter (“Ethernet Mode”) (see paragraph 18.2).
The “LAN/WAN” mode is needed when the “industrial” network connected to the LAN interface
(comprising e.g. HMI and PLC devices) shall be separated from the “enterprise” network connected to the
WAN interface (comprising enterprise PCs and servers); when the Z-PASS is remotely accessed through the
WAN interface, only devices connected to the LAN interface can be reached, while access to machines lying
in the enterprise network is forbidden; this is depicted in the following two figures.
