7.4 Wireless GSM/3G router

A wireless GSM/3G router is a good way to access meters remotely via the existing wireless

networks. There are many wireless routers available, check with your Unipower representative for

recommendations of tested solutions that work. The protocol used depends on the wireless network

(2G/3G) and technology the router uses. Commonly supported protocols are GPRS, EDGE, HSDPA

and UTMS.

To use a router with a meter (UP-2210 or UP-2210R etc) the following must be done:

 The SIM card used must have no PIN-code and it must have a public, static ip-address.

 The router must be set up to forward UDP traffic on port 16421 to the meter’s local ip-

address on the inside LAN of the router. If multiple meters are connected to the same router

you use different port numbers on the outside and route them to UDP 16421 on the inside to

each meter’s local ip.

 Connect the meter to the router using a standard RJ-45 ethernet patch cable. If multiple

meters are used you may need to connect a standard Ethernet switch between the router and

the meters.

Example of settings from a typical router:

Figure 34

Note how UDP 16427 is routed to UDP 16421 ip 192.168.1.7. The meter given the ip 192.168.1.7

will respond to communication on UDP port 16427 to the router’s (actually the SIM card’s) public

ip.
