HowTo: Modified 128 Channel Hill controller with 6 channel remote outlets
( anthony childers)
Step 1 : Build a 128 channel board
|
| | First, build a board. I used the Hill 320 plans, but for my setup, I only wired 2 banks of 8 chips, for a total of 128 circuits. I am not posting a picture due to the cosmetic imperfections of the jumpers and connections. Least to say it all worked for me. What I will show is the finished Controller. Instead of using Hill's serial ports, I paired my outputs in groups of 6 and used cat 5 jacks, NOTE THE PHOTO.
These are patch panel inserts that i got for 16.95 for the whole panel. I seperated them and stacked them as you see. My outputs only use 22 ports, so i tied the last 2 ports to the 10 data lines, and 2 power connections, that way, all I have to do for future expansion is add 2 short CAT5 jumpers to a new box and i can expand my bank of 374 IC's.I also added in a Hex inverter CMOS chip with all inputs tied to the 1st data line in from the parallel port. Each output of the hex inverter connects to the 7th pin of 4 jacks. the 8th pin is ground. Also note in the photo the 7 segment LED pigtail, this tests the operation of each jack, and cable run to ensure signals are working.
