192.168.10.xxx IP number range, as suggested here. Use CAT5 Ethernet cables to connect
Unisab III to the switch or router.
If you do not intend to connect to an external network, such as the Internet or an Intranet, it
is sufficient to use a switch to interconnect between up to 14 Unisab III units.
If you intend to connect to an external network, such as the Internet or an Intranet, you must
use a VPN router (or alternatively a router with a build-in firewall). You may use a Linksys
type RV042 VPN router but note that it is intended for office use and installation. It should not
be mounted in an industrial environment such as a machine room. Industrial types of VPN
routers are also available but at a higher cost.
Consult the Router manual for WAN and LAN set-up.
For the Linksys type RV042 router you need to set up two pages. First connect to the router
default IP address (192.168.1.1) with a browser as described in the Linksys manual.
In the Linksys page Set up > Network, enter the LAN setting as suggested in Fig. 39 (corre-
sponding to the Unisab III IP setting). Enter the WAN connection type setting as supplied by
the net operator.
In the Linksys page VPN > PPTP Server Network, click Enable PPTP Server and enter a VPN
client range e.g. 192.168.10.200 to 204. Maximum five concurrent VPN clients are possible.
Now you can define the needed number of VPN client, i.e. user names and passwords.

8.5.3 Configuration of RS485 port/Danbuss
See subsection 6.4.6. Communication for the software set-up of the RS485/Danbuss port in
Unisab III.
The communication number Compr. must be defined to a number between 1 and 14. You
must also define the communication speed baud rate which is normally set to 19200. See also
the Unisab III sequence manual.
The RS485/Danbuss cable is a screened two wire twisted cable. It is daisy-chained from Uni-
sab to Unisab. Three/six terminals are used. For the electrical connections see Fig. 40 for plug
X11. Use jumper S1 to terminate the Danbuss network in the first and last Unisab III. To
avoid communication problems (noise) ensure that all Unisab III units on the same Danbuss
network are properly grounded to a common ground with a 6â–¡PVT Green/Yellow cable.
