DM0 to DM9: Dimmer data
This dimmer data controls the duty of the G1 to G11 digit output pins and the S1 to S43 segment output
pins. It consists of 10 bits, of which DM0 is the LSB. This dimmer data sets the VFD intensity to one of
993 levels. The following table gives the relationship between the dimmer data and the dimmer level.

Tdig: Single-digit display time (See Figure 4.)
Ton: Single-digit on time (See Figure 4.)
If distortion of the digit waveforms and segment waveforms by the VFD panel used and the wiring causes
spurious glowing of the VFD panel dimly, we recommend setting the dimmer level to a smaller value.
GN0 to GN3: Number of display digits data
This data give the number of digits displayed by the VFD panel, a number between 4 and 11.
The following table gives the relationship between this setting and the digit output pins used.

G1 to G10
G1 to G11
For example, if the VFD panel displays six digits using digit output pins G1 to G6, set GN0 to 0, GN1 to
1, GN2 to 1, and GN3 to 0.

D388 to D430 . . . . . . . Display data for digit output G10

The number of display data bits transferred depends on the number of digits displayed. For example, if the
VFD panel displays six digits, display data bits D1 to D258 are transferred. There is no need to transfer
display data bits D259 to D473.
