26. USING COMMUNICATION FUNCTION
Communication function can download the sewing data created with other sewing machine, creation of sew-
ing data and sewing data created by editing device PM-1 to the sewing machine. In addition, it is also possi-
ble to upload the aforementioned data on a medium.
A medium and a USB port are provided as communication media.

Inserting the CompactFlash (TM)
■
1) Turn the label side of the CompactFlash(TM) to
this side (place the notch of the edge to the rear.
) and insert the part that has a small hole into the
panel.
2) After completion of setting of the media, close
the cover. If the cover cannot be closed since the
memory media comes in contact it, check the fol-
lowing:
Check that the media is securely pressed
・
until it goes no further.
Check that the inserting direction of the me-
・
dia is proper.
1. When the inserting direction is wrong, panel or media may be damaged.
2. Do not insert any item other than the CompactFlash (TM).
3. The media slot in the IP-420 accommodates to the CompactFlash (TM) of 2 GB or less.
4. The media slot in the IP-420 supports the FAT16 which is the format of the CompactFlash
(TM). FAT32 is not supported.
5.
Be sure to use the CompactFlash (TM) which is formatted with IP-420. For the formatting
procedure of the CompactFlash (TM), see "26-3 Performing format" p.87 .

Removing the CompactFlash (TM)
■
1) Hold the panel by hand, open the cover, and
press the media ❷ removing lever ❶. The media
is eject.
When the lever ❶ is strongly pressed,
the media ❷ may be broken by protrud-
ing and falling.
2) When the media ❷ is drawn out as it is, removing
is completed.
USB port ]
[
Inserting a device into the USB port
■
Slide the top cover and insert the USB device into
the USB port. Then, copy data to be used from the
USB device onto the main body.
After completion of copying the data, remove the
USB device.
❶
❷
Disconnecting a device from the USB port
■
Remove the USB device. Put the cover back in
place.
Cautions when using the media
• Do not wet or touch it with wet hands. Fire or electric shock will be caused.
• Do not bend, or apply strong force or shock to it.
• Never perform disassembling or remodeling of it.
• Do not put the metal to the contact part of it. Data may be disappeared.
• Avoid storing or using it in the places below.
Place of high temperature or humidity / Place of dew condensation /
Place with much dust / Place where static electricity or electrical noise is likely to occur

Page 90
Precautions to be taken when handling USB devices
①
• Do not leave the USB device or USB cable connected to the USB port while the sewing machine is in opera-
tion. The machine vibration can damage the port section resulting in loss of data stored on the USB device or
breakage of the USB device or sewing machine.
• Do not insert/remove a USB device during reading/writing a program or sewing data.
It may cause data breakage or malfunction.
• When the storage space of a USB device is partitioned, only one partition is accessible.
• Some type of the USB device may not be properly recognized by this sewing machine.
• JUKI does not compensate for loss of data stored on the USB device caused by using it with this sewing ma-
chine.
• When the panel displays the communication screen or pattern data list, the USB drive is not recognized even if
you insert a medium into the slot.
• For USB devices and media such as CF(TM) cards, only one device/medium should be basically connected/
inserted to/into the sewing machine. When two or more devices/media are connected/inserted, the machine will
only recognize one of them. Refer to the USB specications.
• Insert the USB connector into the USB terminal on the IP panel until it will go no further.
• Do not turn the power OFF while the data on the USB ash drive is being accessed.
USB specications
②
• Conform to USB 1.1 standard
• Applicable devices *
1 ����
Storage devices such as USB memory, USB hub, FDD and card reader
• Not-applicable devices �� CD drive, DVD drive, MO drive, tape drive, etc.
• Format supported �����FD (oppy disk) FAT 12 Others (USB memory, etc.), FAT 12, FAT 16, FAT 32
• Applicable medium size �FD (oppy disk) 1.44MB, 720kBOthers (USB memory, etc.), 4.1MB ~ (2TB)
• Recognition of drives ��For external devices such as a USB device, the device which is recognized first
is accessed. However, when a medium is connected to the built-in media slot, the
access to that medium will be given the highest priority. (Example: If a medium is in-
serted into the media slot even when the USB memory has already been connected
to the USB port, the medium will be accessed.)
• Restriction on connection �Max. 10 devices (When the number of storage devices connected to the sewing ma-
chine has exceeded the maximum number, the 11th storage device and beyond will
not be recognized unless they are once disconnected and re-connected. )
• Consumption current ��� The rated consumption current of the applicable USB devices is 500 mA at the max-
imum.
*1: JUKI does not guarantee operation of all applicable devices. Some device may not operate due to a compati-
bility problem.

26-3 Performing format
In case of re-formatting the media, be sure to perform it with IP-420. The media formatted with the personal
computer cannot be read with IP-420.
Display the media format screen.
①
When key is held pressed for three sec-
onds, MEDIA FORMAT button
A
is
displayed on the screen. When this button is
pressed, the media format screen is displayed.
Start formatting of the media.
②
Set the media you desire to format to the media
slot, close the cover, press ENTER button B and
formatting starts.
Save necessary data in the media to the other
medium before formatting. When formatting is
performed, the inside data are erased.
A
B
When two or more media are connected to the sewing machine, the medium to be formatted is
determined by the predetermined priority order.
High ← Low
CF(TM) slot ← USB device 1 ← USB device 2 ← ....
When a CompactFlash (TM) is inserted in the CF(TM) slot, the CompactFlash (TM) will be for-
matted according to the priority order as shown above.
Refer to the USB specications for the priority order of access.

①
For handling way of the media, read
Performing communication by using USB
②
“26. USING COMMUNICATION FUNCTION” p.83
Data can be sent/received to/from a personal
computer or the like, by means of a USB cable.
If the contact part becomes dirty, failure
of contact will be caused. Do not touch
by hand, and control so that dust, oil or
other foreign material does not adhere
to it. In addition, the inside element is
damaged by static electricity or the like.
So, be very careful when handling.
