Here is the list of topics about this product that receive the most technical support enquiries.
We list them here to help you speed up the installation and trouble shooting process.
90% of installation faults are caused by wiring errors on the RS485 data line.
Special attention to getting this right first time saves a lot of time and effort.
5 - TCP/IP communication over a WAN.
Q
We need to establish two-way communications between a PC on site A and a
Q
Net2 485 TCP/IP Ethernet interface on Site B.
Q
Each site needs to know the gateway IP address required to route data to the other
Q
site and the IP address of the unit they are trying to locate.
Q
- PC Setup (Site A)
Q
The IP routing at Site A is done automatically by network hardware.
Q
LAN addressing is normally set up such that different groups are reserved for specific
Q
remote sites (10.20.x.x, 10.30.x.x, etc). In this case, messages that are for the Ethernet
Q
interface on site B (e.g. 10.20.0.25) will be routed out through the correct gateway by
Q
their network hardware.
Q
The IP address of the PC is included in the outgoing message and will be used by the
Q
Ethernet interface as the return address when it responds.
Q
- TCP/IP Interface Setup (Site B)
Q
This requires an IP address and a gateway to be loaded in the unit before it is taken to site.
Q
Using the Net2 Server Configuration Utility, set the IP address for the Net2 485 TCP/IP
Q
Ethernet interface that defines it within it's own LAN. (e.g. 10.20.0.25) and the IP of the
Q
gateway (e.g. 10.20.0.1) it will use to respond to data from site A.
Q
Port '9999' must be allowed through any firewall software!
