IR 23

From Konstantin Butorin To All 11 June 2002

Hi, All! I almost connected HAYES via LPT. You just need to figure out the addresses. Yes here: HOW TO CONNECT IR23 SO THAT IT STORE THE SET VALUES AT THE OUTPUT? the method of scientific poking does not help. Table too. I can throw a diagram - but I’m in it I didn't understand anything. Maybe someone can explain... ┌──┬────┬──┐ 1 ─oER│RG │Z │ ├──┤ │ │ 11 ─.C │ │ │ __ ├──┤ │ │ ER - read input ER 3 ─┤D0│ │Q0├─ 2 Q - outputs of Q bits 4 ─┤D1│ │Q1├─ 5 D - information input D 7 ─┤D2│ │Q2├─ 6 C - synchronization input 8 ─┤D3│ │Q3├─ 9 13 ─┤D4│ │Q4├─ 12 14 ─┤D5│ │Q5├─ 15 17 ─┤D6│ │Q6├─ 16 18 ─┤D7│ │Q7├─ 19 └──┴────┴──┘ ╔════════════╤══════╤══════════╗ ║ INPUTS │OUTPUTS│ ║ ╟────┬───┬───┼──────┤ MODE ║ ║ ER │ D │ C │ Q │ WORKS ║ ╟────┼───┼───┼──────┼──────────╢ ║ 0 │ D │_|"│ D │ TRANSMISSION ║ ╟────┼───┼───┼──────┼──────────╢ ║ 0 │ X │ 0 │Q(n-1)│ ║ ║ 0 │ X │ 1 │Q(n-1)│READING║ ║ 0 │ X │"|_│Q(n-1)│ ║ ╟────┼───┼───┼──────┼──────────╢ ║ 1 │ D │_|"│ Z │ RECORD ║ ╟────┼───┼───┼──────┼──────────╢ ║ 1 │ X │ 0 │ Z │ ║ ║ 1 │ X │ 1 │ Z │ STORAGE ║ ║ 1 │ X │"|_│ Z │ ║ ╚════╧═══╧═══╧══════╧══════════╝ Printed (C) -=SADIST=- Bye All...

IR23 has been recording input data on the positive edge at the outputs all its life synchronization signal. It was even indicated on your sign... __ And the “read input” is actually an EO signal, if there is a “1” at which the outputs are transferred to a high-impedance state (in short, to a Z-state).
