The driver has 16 jacks (one per column) for switching digit pixels.
Figure 12
shows the pin
assignments and color code for the plugs that mate to these jacks. The jacks are divided into two
groups as follows:
Master Digits:
J1, J3, J5, J7, J9, J11, J13, J15
Slave Digits:
J2, J4, J6, J8, J10, J12, J14, J16
Plugs from all the digits are connected directly into these jacks on the driver.

all operations of the display. It keeps track of the time and stores programmed values. The
