PART 2
INTRODUCTION TO DIGITAL COMMUNICATION
2.1 O er iew
This manual describes how to use a digital communication link and i-SERIES or
MODBUS communication rotocols to o erate the i-Series controllers. It has been
assumed that the user has some ex erience of communication rotocols and some
familiarity with i-Series controllers.
2.2 Definitions of terms
This guide is intended to hel the user to become familiar with digital communication
between a com uter (or other controlling instrument) and one or more devices.
User of this manual should be familiar with following definitions:
• Serial Communication is the exchange of the data one bit at a time on a single data
line. Serial com ares with arallel communication, which sends several bits of
information simultaneously over multi le lines or channels.
• Interface are connections over which com uters communicate. They may use one air
of wires to send information in one direction and another air to send in the o osite
direction (full duplex). They may also use one air to send the information in both
directions (half duplex).
• Bit is a unit of digital data (binary digit) either a “1” or “0”.
• Byte is a string of seven or eight bits, which re resents a single character.
• ASCII (American Standard Code for Information Interchange) – is a 7-bit code defines
128 characters, which include digits, u er and lowercase letters, unctuation symbols,
and control codes such as backs ace, line feed, carriage return and so on. The ASCII
code can be written in a base – 16 number system, called hexadecimal (“hex”). The first
10 digits of this system are re resented by the numbers 0 through 9, and the other six
digits are re resented by the letters A through F. The 128 ASCII character code with the
decimal, hexadecimal and binary equivalents is listed in A endix B.
• Synchronous and Asynchronous Communications
There are two basic ty es of serial communications, synchronous and asynchronous.
With synchronous communications, the two devices initially synchronize themselves to
each other, and then continually send characters to stay in sync. Asynchronous means
“no synchronization”, and thus does not require sending and receiving idle characters.
However, the beginning and end of each byte of data must be identified by start and sto
bits. The serial orts on IBM-style PCs are asynchronous devices and therefore only
su ort asynchronous serial communications.
• Start and Stop Bits
The start and sto bits identify the beginning and end of each character and ermit a
receiver to resynchronize a local clock to each new character. The start bit indicates
when the data byte is about to begin and the sto bit signals when it ends. The start bit is
always a 0. The sto bit is always a 1.
3

• Parity Bit
Besides the synchronization rovided by the use of start and sto bits, an additional bit
called a arity bit may o tionally be transmitted along with the data. A arity bit affords a
small amount of error checking, to hel detect data corru tion that might occur during
transmission. You can choose either e en arity, odd arity or no arity at all. When
even or odd arity is being used, the number of marks (logical 1 bits) in each data byte
are counted, and a single bit is transmitted following the data bits to indicate whether the
number of 1 bits just sent is even or odd.
For exam le, when even arity is chosen, the arity bit is transmitted with a value of 0 if
the number of receding marks (1’s) is an even number. For the binary value of 0110 0011
the even arity bit would be 0. If even arity were in effect when the binary number
1101 0110 is sent, then the arity bit would be 1. Odd arity is just the o osite, and the
arity bit is 0 when the number of mark bits (1’s) in the receding word is an odd number.
Parity error checking is very rudimentary. While it will tell you if there is a single bit error
in the character, it doesn't show which bit was received in error. Also, if an even number
of bits are in error then the arity bit would not reflect any error at all. No arity ignores
the arity bit. When transmitted, each character is receded by a start bit and followed
by a sto bit lus an o tional arity bit, making train of 10 or 11 bits for each transmitted
character. The Figure 2.1 below shows transmission of the 7 bits of the ASCII lower case
“c” with start, sto and even arity bits.
• Baud Rate
The baud rate refers to the data transmission. It s ecifies the communication rate over
the bus. When a change in signal re resents one data bit, baud rate is equal to bits er
second (b s). Standard baud rates for com uters are 300, 600, 1200,2400, 4800, 9600
and 19200 baud.
Figure 2.1 Transmission of “c” with start, stop, and e en parity bits.
• Communication Protocol
A data communication rotocol defines the rules and structure of messages used by all
devices on a network for data exchange. This rotocol also defines the orderly exchange
of messages, and the detection of errors. i-Series controllers use i-SERIES and
MODBUS communication rotocols.

PART 3
HARDWARE
3.1 Communication Interfaces
Two communication interfaces are su orted in the i-Series devices: RS-232 and
RS-485. These standards define the electrical characteristics of a communication
network.
• The RS-232 standard (point-to-point) allows a single device to be connected to a PC.
The i-Series devices o erate with full-du lex RS-232 using three wires: a Rx - receive
wire, a Tx - transmit wire and a common ground wire. RS-232 cable length is limited to
50 feet.
• The RS-485 standard (multipoint) allows one or more devices to be connected
(multi-dro ed) using a two wire connection (half-du lex) +Rx / +Tx and -Rx / -Tx.
Use of RS-485 communications allows u to 32 “remote” devices to connect to the
“master” com uter with cable length u to 4000 feet long.
• Both interfaces use standard RS-232/RS-485 voltage levels.
Although the RS-485 is commonly referred to as a “two wire” connection, the
i-Series also rovides a ground / return shield connection to use as a common
connection for EMI noise rotection.
The Table 3.1 shows the differences between RS-232 and RS-485 communication
interfaces.
Table 3.1 Communication Interfaces
Data Transmission Characteristics RS232 RS485
Transmission Mode Single ended Differential
Electrical connections 3 wire 2 wire
Drivers er line 1 driver 32 drivers
Receivers er line 1 receiver 32 receiver
Maximum data rate 20k bits/s 10M bits/s
Maximum cable length 50 ft (15 meters) 4000 ft (1200 meters)
Changing between RS-232 and RS-485 is ossible through front anel buttons
(see Part 4 for details).
3.2 Wiring RS-232 Interface
Most PC’s rovide an RS-232 ort for digital communication. The RS-232 communication
uses three wire full-du lex system: a line for receiving data, a line for transmitting data
and a common line between the com uter and device. Usually PCs use a 25 or 9 in
connector.
Caution: Do not connect ower to your instrument until you have com leted all
serial interface connections. Failure to do so may result in injury.

Communications Parameters Submenu
Allows the user to adjust Serial Communications settings of the device. When
connecting an instrument to a com uter or other device, the Communication Parameters
must match. Generally the default settings shown in Table 4.1 should be utilized.
Bus Format Submenu
Determines communications standards and command/data formats for transferring
information into and out of the device via the Serial Communications Bus.
Bus Format submenus essentially determine how and when data can be accessed via
the Serial Communications of the device.
Data Format Submenu
Preformatted data can be sent automatically or u on request from the device. Use the
Data Format Submenus to determine what data will be sent in this reformatted data
string. At least one of the Data Format subo tions must be enabled to send out ut data
to the Serial Bus.
Recognition Character
A selectable symbol transmitted as the first character of each message from the
com uter, which is used for message security: the meter ignores messages without this
symbol.

PART 5
i-SERIES PROTOCOL
To Enable the i-Series Protocol, set Modbus menu item to “No” in the Bus
Format Submenu of the Communication Menu. Refer to Section 5.7.11.
A Data Communication Protocol defines the rules and structure of messages used by all
devices on a network for data exchange. A ty ical transaction will consist of a request to
send from the “master” followed by the res onse from the “slave”.
5.1 Command Structure
The device can be commanded to “Read”, i.e., to transmit (send) data from either the
nonvolatile memory (EEPROM) or from the volatile working memory (RAM).
The device can also be commanded to “Write”, i.e., store new values for data rocessing
or control.
There are different command ty es associated in communicating with your meter shown
in Table 5.1, which shows the Command Prefix Letters (Command Classes).
Table 5.1 Command Prefix Letters

Where:
“*” is the selected Recognition Character. You may select any ASCII table symbol from
“!” (HEX address “21”) to the right-hand brace (HEX “7D”) exce t for the caret “^”, “A”,
“E”, which are reserved for bus format request.
“ccc” stands for the hex-ASCII Command Class letter (one of eleven given in Table 5.1),
followed by the two hex-ASCII Command Suffix characters identifying the meter data,
features or menu items to which the command is directed (given in Table 5.3).
“<data>” is the string of characters containing the variable information the com uter is
sending to the meter. These data (whether BCD or binary) are encoded into hex-ASCII
characters, two characters to the byte. Square brackets (indicating o tional status)
enclose this string, since some commands contain no data.
“<nn>” are the two ASCII characters for the device Bus Address of RS-485
communication . Use values from “00” to hex “C7” (199 decimal).
Table 5.3 and 5.4 shows the command letters and suffix for i-Series devices.
