1 Overview
(1) TFIR-31LAN series image reader is fixed mount (stationary type) image reader capable
of reading both linear (1D) bar codes and two-dimensional (2D) codes. These units
incorporate the most innovative digital camera technologies, related image recognition,
and processing software. The image reader can read both 1D and 2D symbols, with auto
discrimination of symbol type and omni-directional (360-degree rotation) reading. This
manual may also refer to 1-dimensional and 2-dimensional barcodes as “symbols”.
(2) The TFIR-31LAN series image reader has RS232C and Ethernet (10BASE-T) interface,
and can be connected easily to a Windows PC.
Windows 2000, Windows XP, Windows Vista and Windows 7 are supported.
zWindows is a registered trademark or trademark of Microsoft Corporation in the United States or
other countries.
zIf the image reader does not work in your system environment with Windows PC, please contact
your local sales representative.
(3) The TFIR-31LAN series image reader incorporates functionality to read DPM symbols
(Direct part marking symbols) which are printed directly on objects such as Laser marking
and Dot Peen Marking.
Image Preprocessing:
This function uses MARS TOHKEN SOLUTION’s latest image processing
algorithms to improve deteriorated pictures to provide the user with the best
reading performance.
Table Mode:
Combining multiple functions (Shutter Speed, Gain, Image Processing, etc),
this function executes the image capture and image processing automatically
in the order appointed to maximum of 8 configurations.
(4) If there are any difficulties configuring the input SYNC signal to a proper timing, please
use the MAXIMG function to continuously capture images during the configuration period.

(5) The TFIR-31LAN series image reader has two types of internal illumination source as
follows.
TFIR-31LAN-H : Spot illumination source and diffused illumination source
TFIR-31LAN : Spot illumination source A and spot illumination source B

1.2.1 Monitor LED
1.2.1.1 Function of monitor LED
Note: The function of monitor LED differs in automatic tuning mode for camera
settings. Please refer to section 5.5 for the detailed information.
1.2.2 Teach button
The Teach button is used for automatic tuning (Refer to section 5.5).
1.2.3 Read button
The Read button acts as a trigger for the reader. It is also used for automatic
tuning (Refer to section 5.5).
1.2.4 LAN connector
•LAN interface (LAN)
Send and receive data to/from host device. LAN cable is not included.
LAN indicator (Green): On when the LAN connection is established.
LAN indicator (Red): Blinking when data is being transferred.
LED Color Name Description
A Red Ready Turn on when the reader is ready to work
B Green Sync Turn on when the reader receives SYNC signal

1.2.5 DIO connector
•2 Digital Outputs: GO, NG
Three photo coupler isolated outputs are available.
“GO” and “NG” are used to signal the result of decode. These signals can also
be configured to be “Ready” and “Busy” by the serial command. Refer to section
7.13 General Operation for detailed information.
1.2.5.1 Detail of the GO & NG singnal
Signal name Description
GO signal GO signal is associated with Good Read, which is ON
during the specified time set by the GOOUT command
when the symbol is decoded successfully. And also this
signal is OFF when starting the next reading.
NG signal NG signal is associated with No Read, which is ON
during the specified time set by the NGOUT command
when the symbol is not decoded successfully. And also
this signal is OFF when starting the next reading.
Ready signal Ready signal is ON when the reader is ready for reading.
Busy #1 signal Busy #1 signal is ON while the reader is reading (except
switch chattering delay), and this signal will be OFF after
decoding.
Busy #2 signal Busy #2 signal is ON while the reader is reading (except
switch chattering delay), and this signal will be OFF after
transmission of the decoded data.
In the factory default settings the signals are as below:
GO ÆGO signal, NG ÆNG signal
When changing these parameters, save the settings to the internal flash
memory (using the WSETS command) and turn off the power and on it again.
Using the “Busy #2 signal”, make sure the settings of RSCS=1 and TCPCS=1.
•1 Digital Input: SYNC
This signal is used to initiate reading.
(Sync signal can be sent by the serial command as well.)

•DIO cable assembly
To interface with external equipment, use an accompanying DIO-plug
connector.
- Stripped off about 8mm in length of the outer jacket of a wire, and then use a
small screwdriver to hold down the small orange tab. After that, insert the
wire into the insertion opening next to the tab of the DIO-plug connector.
- The wire is locked when releasing the tab.
Note: The DIO-plug is attached to the DIO-socket (Factory default).
Applicable wire : AWG#20 to 26
Stripping length : 8mm
DIO connector socket : MC 0,5/ 5-G-2,5（PHOENIX CONTACT）
DIO connector plug : FK-MC 0,5/ 5-ST-2,5（PHOENIX CONTACT）
DO NOT unplug the DIO-plug by grasping the cable. It may cause breaking of wire.

1.2.6 Interface cable
RS232C and power input for the reader.
•RS232C interface: RxD, TxD, CTS, RTS
Through RS232C, the reader sends the reading data and status to the host
computer. This interface also receives configuration commands from the host
device.
•DC power jack
5Vdc power is supplied from/through the optional AC adapter.
1.2.7 Internal illumination source
TFIR-31LAN-H
The spot type light source illuminates the central part of the image reader’s field
of view.
The diffused type light source illuminates the entire field of view.
TFIR-31LAN
The spot type-A light source illuminates the peripheral part of the field of view.
The spot type-B light source illuminates the central part of the field of view.
1.2.8 Camera lens
The reader captures images through the lens.

2 Configuration
2.1 Preparation
1- Establish communication between the reader and a host device. Please
refer to section 2.3 Communication port selection (RS232C, LAN) for
detailed information.
2- Supply power from the interface cable to the reader. The LED-A (Ready)
turns on (red) if the reader is correctly powered. A combination of 2 long
beeps and 3 short beeps will indicate that the reader has started up
correctly.
