1.Communication overview
1.1 Overview
1.1.1 Serial communication
The functions described in this document are used to transmit printings and their registration
numbers and enter them into the IJ printer with an external device connected to the IJ printer
via an RS-232C serial communication line. Connect the USB serial converter to the USB port
of the IJ printer and use RS-232C serial communication via the USB serial converter.
1.1.2 Ethernet communication (Tunnel communication)
Ethernet communication supports the same contents as RS-232C serial communication.
Because it uses the same mode of communications as previous models, if RS-232C serial
communication is already employed for the IJ Printer, you can create a communications program
for the host device using this asset.Please refer to Communication User’s manual (Serial Communication)
for details of this function.
1.1.3 Ethernet communication (Modbus communication)
This function allows you to change the settings of the IJ printer by transmitting the
print contents, print specifications, etc. between the external device and the IJ printer
using the LAN environment. Modbus is an industrial multi-vendor network using
Ethernet, and its communication specification is adopted as an open standard in
various industrial equipment. Messages that the IJ printer voluntarily outputs, such as
status output and print content output, do not correspond.
For the Modbus communication, it is necessary to develop a communication program
on the external device side.
1.1.4 Ethernet communication (OPC-UA communication)
This function allows you to change the settings of the IJ printer by transmitting the
print contents, print specifications, etc. between the external device and the IJ printer
using the LAN environment. OPC-UA is an industrial multi-vendor network using
Ethernet, and its communication specification is adopted as an open standard in
various industrial equipment. Messages that the IJ printer voluntarily outputs, such as
status output and print content output, do not correspond.
For the OPC-UA communication, it is necessary to develop a communication program
on the external device side.
1.1.5 Ethernet communication (EtherNet／IP communication)
It is a function to communicate with an IJ Printer via Ethernet from an external device using
the network environment.
EtherNet/IP is an industrial multi-vendor network using Ethernet, and its communication
specification is adopted as an open standard in various industrial equipment.
EtherNet/IP communication has two communication functions: “Message communication
(Explicit communication)” that communicates at an arbitrary timing and “Cyclic
communication (Implicit communication)” that communicates at a fixed cycle.
For the EtherNet/IP communication, it is necessary to develop a communication program on
the external device side.

■Glossary
Terminology
Explanation
IP address
(Internet protocol address)
The IP address is a 32-bit ID number allotted to equipment
connected to the Internet. The 32-bit number of the IP address is
usually divided into four 8-bit segments for display. The IP
address consists of a "network address" that identifies the
network and a "host address" that identifies the individual pieces of
equipment connected in the network.
Subnet mask
The subnet mask is a 32-bit number that defines what bits of the
IP addresses are used for the network address. The network
address segment of the IP address is determined by calculating
the logical AND of the IP address and subnet mask.
Default gateway
The default gateway is equipment such as a router that functions as
the "gateway" to the network. When there is communication
between different networks and there is no unique path for the
equipment to be accessed, the default gateway is used to connect
them.
Port number
The port No. is the sub-address that specifies one of several
programs running on equipment specified by the IP address.
Port numbers 502 or 1024-65535 are used as the sub-address.
MAC address
It is a number registered to identify the device on the network.
The MAC address consists of 12 digits like 01-23-45-67-89-AB.
Connect the LAN cable

3. Connection test
Directly connect the IJ Printer to a PC and check the connection.
3.1 Procedure for connection test
１ Directly connect the IJ Printer to the PC with a LAN cable.
２ Set the network settings of external unit by steps２ to ５.
Click the Start menu,and double-click [Windows System] > [Control Panel] >
[View network status and tasks] > [Change adapter settings]> [Ethernet].
The following window is then displayed.
３ Click [Properties].
（Example using Windows 10 OS）

9
４ Click [Internet Protocol Version 4 (TCP/IPv4)].
５ Select [Use the following IP address], and enter an IP address other than 192.168.0.1 and 192.168.0.255
(the example shown in the figure uses 192.168.0.15) and then enter 255.255.255.0 in the Subnet mask field.
Click [OK].

10
６Follow the steps below to confirm that the network connection is properly established. The following steps
describe procedures for Windows 10.
Select [Start Menu] > [Windows System]
> [Command prompt] to open the
Command Prompt window.
Type the following command:
Ping 192.168.0.1
Note:
This command is not case sensitive.
Byte=32 time=24 ..in four consecutive
lines*1 then external unit settings are
completed.
*1:
In default, the ping command returns
the response for four times. For details
of the ping command, type the
following command: ping/help
If "Destination host unreachable."
response is returned for the ping
command, it means communication
has not been established between the
IJ Printer and external unit. Re-check
the following:
[Check points]
* Have the communication settings of
the IJ Printer been changed?
* Are the network settings of the
external unit correct?
