RE2100

5.6

KEYBOARD UNIT (MODULE 6) PART NO. 625636

The keyboard consists of a 4x8 matrix of which 26 keys are used. One side is connected to the
microprocessor data bus by an 8 bit driver. The other side is connected to 4 of the microprocessor ports.
By setting the 4 ports high and reading the data bus alternately it is possible to determine which key has
been activated. In this way the keyboard is scanned 100 times per second.
The keyboard light, consisting of 13 LEDs divided in 5 columns, is controlled by an open collector (Q02)
on the display print PCB, module 7. The power in each column is approx. 8.5 mA.
