1-2 The difference between A88 and C88
The difference between A88 and C88 is that C88 have the function of Coiling,
Taping and Zigzag Embroidery and C88 have the validation of factory ID, but
A88 have not. Other operations or functions is same.
1-3 Main Features
1. User Friendly Touch Screen
Adoption of touch screen technology offers delightful operation and easy learning.
The beautiful screen display turns everyday work into joyful experiences.
2. Shutdown of LCD Display
Following measures were taken in order to extend the LCD life: LCD will turn off
automatically in case of no operation in 10 minutes (the time can be changed in
parameter setting). A touch of the screen or the task-shifting key will reboot the
LCD.
3. Super-Large Memory Capacity
The memory capacity reaches 16 million stitches, in which 400 designs can be
restored. Its super-large memory capacity can meet demands of different

Chapter 1 General Descriptions
4 BECS-A88/C88computerizedembroiderymachineowner’smanual
customers.
4. Maximum 1 Million Stitches for 1 Design
At present a single design in the system has the maximum of 100,000,000 stitches
and 250 times of automatic color changing.
5. Multi-Task Parallel and Free Shift among Tasks
During embroidering, actions like design input & output, preparation for the
following designs and modification of parameters can be carried out. Flexible
shift among tasks can be realized by using the task-shifting key.
6. Storage of Frequently Used Parameters and Color-Changing Order for Each
Design
Design will be saved along with its parameters, color-changing orders and needle
bar colors. System can memorize the operational details for each design. Users
can set parameters for a design during the embroidery process of the previous
design, which will help saving time and improving efficiency. More importantly,
it is one basis to realize network management.
7. Group Management of Parameters
Parameters can be divided into three groups: frequently modified parameters,
practical parameters for embroidery technicians and machine parameters for
machine manufacturers. The last two groups of parameters can be restored,
recovered and password-protected.
8. Input & Output Using USB
Except for DOS, FDR and ZSK format, customers can use USB disk for data

Chapter 1 General Descriptions
BECS-A88/C88 computerized embroidery machine owner’s manual 5
transfer. USB disk supports DIR operation, which is easy for design management.
For each directory, system supports operation on 400 designs or sub-directory.
There is no limitation between directory levels. Design designs like DSB and DST
and ZSK and FDR can be loaded.
9. Input of Several Design Files at One Time
Both floppy and USB disks support multi-design input under one directory.
10.Input design through network, color-changing order, etc.
Network connector is available, which help user input design, color-changing
order, patch sewing, etc.
11.Network Function
A surveillance LAN can be built by using the connectors and linked to the factory
LAN, which realizes network management, improve production efficiency and
reduce possible mistakes. It’s the best choice of embroidery equipment for
enterprises to take the modern enterprise management.
12.Patch Embroidery
This function can set a patch code after the color code or stop code, and when the
machine embroiders the patch code, it will halt and move frame out for patching.
After stick a patch, user would pull the operation bar to let the frame move back
and continue embroidering.
13.Break Adjusting
For various machines, this function can make the machines stop correctly, which
means that the main shaft stops at 100 degree.

Chapter 1 General Descriptions
6 BECS-A88/C88computerizedembroiderymachineowner’smanual
14.Starting Point Saving
This function can save and store the start embroidering point of each design,
instead of repeating moving frame manually to find the design origin when
selecting the same design.
15.Mechanical Maintaining and Testing
This function is to easily judge the malfunctions when maintaining and testing,
which consists of computer testing, encoder testing, main shaft speed testing,
machine parts testing and the main shaft stopping at any position, etc.
16.Multi-Language Support
Currently, the system supports language shift among Chinese, English, Spanish
and Turkish.
17.Design Output
Design can be output and saved into floppy disk or USB disk. Adoption of
TAJIMA’s binary system enjoys the advantage of data transmitting through the
World Wide Web (other formats may not be transmitted directly).
18.Repetition Embroidery
The machine can increase embroidery productivity by repetition embroidery,
which can also be used with cyclic embroidery.
19.Cyclic Embroidery
The machine also can increase embroidery productivity by using cyclic
embroidery function, by which the machine automatically returns to the origin
point and starts the same embroidery design again when finishing the design one

Chapter 1 General Descriptions
BECS-A88/C88 computerized embroidery machine owner’s manual 7
time.
20.Design Compiling
(1) Compiling the Data of Selected Design to Generate New Design
Users can compile any design according to zoom ratio, rotate angle, normal
repetition or partial repetition to generate a new design and save it in the memory
card. The newly generated design can be used for embroidering, output or other
operations.
(2) Compiling the Combined Design
System can compile the pre-set combined design to generate a new one and save
it to the memory card. The newly generated design can be used for embroidering,
output or other operations.
21.Letter Design
There are altogether 28 letter-bases. Users can make groups and change the letter
order according to different tasks. This operation is simple and easy managing.
22.Design Editing
By using this function, users may insert, modify or delete certain stitch at the
selected point. New designs can be created by this function too.
23.Speed Adjusting
The highest speed for embroidering can be set. During the process of
embroidering, speed changes automatically as long as the needle interval changes.
24.Thread Trimming
Thread trimming can be manually controlled. Trimming acts automatically at the

Chapter 1 General Descriptions
8 BECS-A88/C88computerizedembroiderymachineowner’smanual
end of embroidery process or color changing.
25.Thread Break Detect
In case of thread break or running out of bottom thread, machine stops and
warning lights start to blink.
26.Color Changing
At the color changing point, user can either act color changing manually or let the
system do according to the preset order automatically.
27.Special Embroidery
BECS-C88 computerized embroidery adds special embroidery functions (coiling,
taping and Zigzag embroidery) on the basis of BECS-A88 system.
28. Setting up B point (Selected)
This function is specially designed for easy threading when thread breaks appear
on giant frame. See 9.16 for details.
29. Function of validation of factory ID（A88 system have not this function）

USB disk can be plugged in for data input/output.
Direction of the Control Panel
In order to extend the life of the control panel, please do not lay too much
pressure on the screen during operation. Try to avoid using hard or shape tools to
touch the panel.
Direction in Using the Floppy Disk
Make sure the plug-in direction is correct. Try to avoid using force with incorrect
plug-in direction, or it may destroy the floppy driver and disk.
Direction in Using the USB Disk
Please pay close attention to electrostatic phenomenon. Don’t forget to discharge
before plugging in/out the USB disk.
USB disk features plug-in direction. Users should avoid plugging out during
