Parallel Interface
7.1.1 Basic Operation
Data (D0-D7) has to be set prior to a rising edge of /WR line, and the data is clocked in on the
rising edge of /WR line.
During data execution, the parallel busy line is high (PBUSY=1).
Writing data when PBUSY = 1 causes data loss, so please write data when PBUSY = 0.

Serial Interface
7.2.1 Basic Operation
Default setting: Asynchronous Serial Interface (Baud rate = 38,400bps)
Either Synchronous or Asynchronous Serial Interface is selectable by jumper setting. Refer to
“8 Jumper Setting” at page 12.
The capacity of the receiving buffer is 64 bytes. The relationship between SBUSY and the
receiving buffer is as follows;
Remaining space of receiving buffer
SBUSY 0 -> 1
SBUSY 1 -> 0
16 byte or less
24 byte or more
Writing data when SBUSY = 1 may cause data loss, so please write data when SBUSY = 0.

and “13.3.45 Serial OUT mode end”.
User Set up Mode
Under this mode, an on-board flash memory is accessible.
The module accepts only three commands: “13.3.40 User set up mode end“, “13.3.41 Define
FROM user font” and “13.3.43 Display status information”.
Serial OUT Mode
Under this mode, status information is readable via Asynchronous Serial Interface.
The module accepts only two commands: “13.3.42 Read status information” and “13.3.45 Serial
OUT mode end”.
Test mode
The module does not accept any commands but displays test-patterns. Test purpose only.

Display Area-End of Line Behavior
In most cases, a cursor moves to the next position after a character is displayed on the current cursor
position, but some exceptional cases exist. At end of line, the next behavior of a display area depends
on the current cursor position, character size and display mode.
Display area behaviors for some magnified character sizes are as follows:
Right Most Column
Regular size (1×1) characters (Over-write mode)
Lower Most Row
Current Cursor Position
The next cursor position is here.
Right Most Column
1×2 Magnified characters (Over-write mode)

Notice for the Cautious Handling VFD Modules
Handling and Usage Precautions:
Please carefully follow the appropriate product application notes for proper usage, safety handling, and operation standards for
maximum performance.
[VFD tubes are made of glass]
•
Because the edges of the VFD glass-envelop are not smooth, it is necessary to handle carefully to avoid injuries to
your hands
•
•
•
•
Please avoid breaking the VFD glass-envelop to prevent injury from sharp glass particles.
The tip of the exhaust pipe is fragile so avoid shock from impact.
It is recommended to allow sufficient open space surrounding the exhaust pipe to avoid possible damage.
Please design the PCB for the VFD-module within 0.3 mm warping tolerance to avoid any forces that may damage
the display due to PCB distortion causing a breakdown of the electrical circuit leading to VFD failure.
[High voltage]
•
•
Avoid touching conductive electrical parts, because the VFD-module uses high voltage exceeding 30～100 volts.
Even when electric power is turned off, it may take more than one minute for the electrical current to discharge.
[Cable connection]
•
Do not unplug the power and/or data cables of VFD-modules during operating condition because unrecoverable
damage may result.
•
•
Sending input signals to the VFD-module during a power off condition sometimes causes I/O port damage.
It is recommended to use a 30 cm or shorter signal cable to prevent functional failures.
[Electrostatic charge]
VFD-modules needs electrostatic free packaging and protection from electrostatic charges during handling and
usage.
[Structure]
•
•
During operation, VFD and VFD-modules generate heat. Please consider sufficient heat radiation dissipation using
heat sink solutions.
•
•
We prefer to use UL grade materials or components in conjunction with VFD-modules.
Wrap and twist motion causes stress and may break VFDs & VFD modules. Please adhere to allowances within
0.3mm at the point of attachment.
[Power]
•
•
Apply regulated power to the VFD-module within specified voltages to protect from failures.
Because some VFD-modules may consume in rush current equal to twice the typical current at power-on timing,
we recommend using a sufficient power capability and quick starting of the power regulator.
VFD-module needs a specified voltage at the point of connection. Please use an adequate power cable to avoid a
decrease in voltage. We also recommend inserting a power fuse for extra protection.
•
[Operating consideration]
•
Illuminating phosphor will decrease in brightness during extended operation. If a fixed pattern illuminates for an
extended period,( several hours), the phosphor efficiency will decrease compared to the non operating phosphor
causing a non uniform brightness among pixels. Please consider programming the display patterns to use all
phosphor segments evenly. Scrolling may be a consideration for a period of time to refresh the phosphor condition
and improve even illumination to the pixels.
•
We recommend using a signal cable 30cm or less to avoid some possible disturbances to the signal.
[Storage and operating environment]
•
Please use VFD-modules under the recommended specified environmental conditions. Salty, sulfur and dusty
environments may damage the VFD-module even during storage.
[Discard]
•
Some VFDs contain a small amount of cadmium in the phosphor and lead in the solder. When discarding VFDs or
VFD-modules, please adhere to governmental related laws or regulations.
[Others]
•
Although the VFD-module is designed to be protected from electrical noise, please plan your circuitry to exclude as
much noise as possible.
•
Do not reconstruct or repair the VFD-module without our authorization. We cannot assure the quality or reliability of
unauthorized reconstructed VFD-modules.
Notice:
･We do not authorize the use of any patents that may be inherent in these specifications.
･Neither whole nor partial copying of these specifications are permitted without our approval.
If necessary , please ask for assistance from our sales consultant.
･This product is not designed for military, aerospace, medical or other life-critical applications. If you choose to use this product
for these applications, please ask us for prior consultation or we cannot take responsibility for problems that may occur.
