IZnet’s Internet chip and module are
getting popular among smart meter
manufacturers in Europe. WIZnet started to
supply the Serial to Ethernet Gateway module to
a Germany company in 2009. Since then, more
than 10 companies have been developing and
manufacturing metering devices by adopting
WIZnet as the Internet connectivity solution.
I
n Europe, the Internet function is basically
required at the end device of metering
system. The following figure shows the block
diagram of the meter device in which WIZnet
chip is applied for the Ethernet function.
