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.

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.

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. STNDARD NAME DOCUMENT NO.

SPECIFICATION FOR APPROVAL REV.NO 1.0 PAGE 10/10 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.
