2.5 High quality vacuum fluorescent display provides an attractive and readable medium.
Other colors can be achieved by simple wavelength filters.
2.6 Characters are provided in an attractive 14-segment starburst format.
3. GENERAL DESCRIPTIONS
3.1 This specification becomes effective after being approved by the purchaser.
3.2 When any conflict is found in the specification, appropriate action shall be taken upon agreement
of both parties.
3.3 The expected necessary service parts should be arranged by the customer before the completion
of production.

5. FUNCTIONS
The module has control data, display data write and reset functions.
Input data from the host system is loaded into the module’s display buffer via the serial data input channel as
8-bit serial data. The MSB value of 8-bit serial data determines whether the input data into this module is
control data or display data.

5.1.1 Buffer Pointer Control
This command changes the display contents only at an arbitrary digit.
(The RAM write address is set.) The digit position to be modified is represented by the value of D3 D0.
If the most significant digit(left-end digit) is to be selected, each of D3 D0 are set to a value of “1” and
if the second digit is to be selected ,each of D3 D3 set to a value of “0”. Otherwise a decimal value of
from “1”to “12” should be entered. The set value of D3 D0 is lower than the decimal value of the
specified position by 2.

5.1.2 Digit Counter Control
This command is used to define the number of display digits. The code is normally used only during
initialization routine of the host system.
If all 13 characters are to be controlled, each of D3 D0 are set to a value of “0”, otherwise a decimal
value from “1” to “12” is entered, corresponding to the actual number of characters to be controlled.

Input Display Data Word
Display data words are loaded into the display buffer of module as 8-bit codes, with the MSB set to “0”. The 64
available codes are shown in Table-13 on next page.
16 display data words must be entered to fully load the display data buffer. The display buffer pointer (write in
position) specified by the buffer. Pointer control command is automatically incremented by one each time the
display data is entered.
To set the comma or decimal point, the display data codes of 2C Hex or 2E Hex is entered respectively. Only
when 2C Hex and 2E Hex data are entered, the display buffer pointer in the RAM is not automatically
incremented but stays present location.

5.3 RESET
The reset function allows the users to re-initialize the alphanumeric display controller, while the power is still
applied to the module, by applying a logical “0” to pin #5 and pin #7(/RST) of the connector. (Pulse Width≥200us)
When the controller is initialized, the display status is shown in Table-13. The RAM data (Display Buffer Data) are
the same as the prior data.

6. OPERATING RECOMMENDATIONS
6.1 Avoid applying excessive shock or vibration beyond the specification for the VFD module.
6.2 Since VFD is made of glass material, careful handling is required.
6.3 When mounting the VFD module to your system, leave a slight gap between the VFD glass and your front panel.
The module should be mounted without stress to avoid flexing of the PCB.
6.4 Avoid plugging or unplugging the interface connection with the power on, otherwise it may cause
severe damage to input circuitry.
6.5 Slow starting power supply may cause non-operation because one chip Mi-com won’t be reset.
6.6 Exceeding any of maximum ratings may cause the permanent damage.
6.7 Since the VFD module contain high voltage source, careful handling is required while power is on.
6.8 When the power is turned off, the capacitor does not discharge immediately.
So the high voltage applied to the VFD must not get in contact with ICs.
In other words, short-circuit of mounted components on PCB within 30 seconds after power-off may
cause damage to the module.
6.9 The power supply must be capable of providing at least 3 times the rated current, because the surge current
may be 3 times the specified current consumption when the power is turned on.
6.10 Avoid using the module where excessive noise interference is expected.
Noise may affect the interface signal and cause improper operation. It is important to keep the length of the
interface cable less than 50cm.
6.11 Since all VFD modules contain C-MOS ICs, anti-static handling procedures are always required.
NOTE: Newhaven Display reserves the right to change or modify this existing specification and or product in
order to improve the quality of this design.
