Up Counter

For example, if two are connected in a manner that input of one becomes the output of other, the second IC will receive a pulse on every tenth count and will reset at every hundredth count. An up counter simply counts from 0 to 9. Output 4, BCD Output bit 3.

You just need to modify connections on pins 2,3,6 and7 of Output 2, BCD Output bit 1. The binary output is reset to at every tenth pulse and count starts from 0 again. Count 0 to 9. Thus this system can count from 0 to 99 and give corresponding BCD outputs. Assembly instructions for Infrared transmitter module.
