Decoder for Vicom

Hi, ALL! I propose a prosthetic decoder circuit (which can be soldered even a baby!) for a Wicom modem. The decoder eliminates false triggering in some programs (which I will not list). The circuit is connected to the D35 IC on the yellow board. Also Mona use free elements on the board - inverter LH1 - D58. 5┌───┐ ┌─┤1 │4 10k │ │ ├────────────┐ 7 (D35) ┌─────┐ │6│ │ │ <────────┤ ├┬┴─┤ │ (D58-3,4) │ └─────┘│ └───┘ │ │ LE1 │ ──┴── │ 8┌───┐ ──┬── └───┤1 │ set │ 0.1 │ ├─────────> K TM9 - D35 │ K555/1533LE1 ┌───┤ │10 ──┴── │ 9└───┘ │ LE1 2┌───┐ │ ┌─┤1 │1 │ 12 (D35) │ │ ├────────────┘ <────────────────┤3│ │ └─┤ │ (D58-10.11) └───┘ LE1 And that's it... ─═ Sergey ═─
