5.1 Type of interface

The following interfaces are available on this module;

Parallel interface (CMOS)

Serial interface (Asynchronous, Possible to input by RS-232 level)

5.2 Parallel interface

5.2.1 Basic function

The module sets the PBUSY line upon receipt of data, and clears the line when ready to receive

more data. PBUSY is readable by Status read of D7 bit or PBUSY signal directly.

RS terminal is reserved for swiching of data and command. This is not available on this module.

Please do not use this terminal.

5.3.2 Asynchronous serial interface timing

* Only 1 byte data can be receipt just after SBUSY=1

Interface:

5.4 Reset timing

Reset pulse (active low) should be longer than 1mS.

The module sets the SBUSY/PBUSY line upon receipt of Reset signal and clears the line when

ready to receive the data.

6.3 Window

Window function divides display screen as “Window” ,and each divided “Window” can be controlled

and displayed independently. Refer to “Window command group”, Page 24.

There is no independed display memories for each “Window”.

There are 2 types of “Window”, Base-Window and User-Window .

6.3.1 Base-Window

This has the whole display screen and if User-Window is not defined, all display operation is

processed under this Base-Window.

When some User-Window is defined, the display operation to the out of display screen of

User-Window should be processed under Base-Window.

When Base-Window is selected even if some User-Window is defined, all of display operation is

processed under Base-Window. Therefore, the current display pattern of User-Window is

overwritten.

6.3.2 User-Window

User-Window is defined by command, and display operation can be processed on

User-Window selected by “Current Window select” command.

User-Window can be defined up to 4 windows.

This effects only for Base Window.

There are two types of Write screen mode, Display screen mode and All screen mode which can be

changed by command. (Refer to Window command group , “Write screen mode select”,Page 26)

6.4.1 Display screen mode (Scanning)

When the cursor is located on the Display area, all of operation will be done within Display area, and

when cursor is located on the Hidden area, it will be done within Hidden area.

6.4.2 All screen mode (Scanning)

All of operation will be done on all of area.

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.
