4.2 Installation methodACR Series Network power meters adopt the

embedded mode as mounting mode, take pressing

mode as fixing mode, concrete operations are

shown as following:

1, On proper place of the distribution

switchboard, make one mounting hole with same

size of multi- function meters cutout;

2, Remove Network power meters, loosening the

positioning screw (counter clockwise), remove

mounting support;

3, Insert meters into meter-hole of distribution

switchboard, after the meter is inserted, restore

mounting support and positioning screw (clockwise).

ACR meters use MODBUS-RTU Communication

protocol, MODBUS protocol to define the check

code, data sequence etc. in detail, they are

necessary content for specific data exchange.

MODBUS protocol use master/slave responding

connection(half duplex)on the same Communication

line. After signal from host computer addressing of

the only one terminal device(slave computer), the

terminal device sends answering signal and

transmit to host computer .

MODBUS protocol only permit the

Communication between host computer(PCPLC

etc.)and terminal device, not permit the data

exchange between independent terminal devices .In

this way, every terminal device does not occupy

Communication line in their initialization, but is

responding to the enquiry signal.

6.1.1 Transmission modeThe information transmission is asynchronous

mode, and take byte as Unit, the Communication

information transmitting between the host computer

and the slave computer is the 10 bit character

format, including one Initial bit, 8 data bit (Firs

Transmitting the least effective bit), without parity

check bit, 1 stop bit.
