green LED - Tx/Rx illuminates when the meter sends and receives data, flickers irregularly,
when no data is transmitted the LED lights up permanently
To connect the meter to the network, use wire twisted pair of STP type (shielded) CAT 5 - for high-
speed local area networks, frequency bandwidth up to 100 MHz according to the European standard
EN 50173 with RJ-45 plug with core color (according to Table 11) in the following standard:
•
EIA/TIA 568A for both connectors at the so-called simple connection of NR30PNET to the
network hub or switch,
•
EIA/TIA 568A for the first connector and EIA/TIA 568B for the second connector at the so-
called patch cord connection (crossover) used, among others, when connecting NR30PNET
to the computer.

MAP OF REGISTERS OF NR30PNET METER
In NR30PNET meter the data is placed in 16- and 32-bit registers. Process variables and parameters of
the meter are located in the address space of registers in a manner dependent on the type of the
variable. Bits in 16-bit register are numbered from the youngest to the oldest (b0-b15). 32-bit registers
contain floating point numbers in IEEE-754 standard. Byte order 3210
– the oldest is sent first.
