I have a House of the Dead (1) board and I'm trying to get it all hooked up. I asked last week in the worrying bomb thread but no luck, I'm hoping someone will see it here. Since then I've spoken to someone who knows more about electronics than me but I'm still in the dark. I have a tri sync monitor which can handle the 25kHz, but I'm very worried about just plugging it in and damaging either my monitor or board.
Here are the input specs of the monitor:
Input Signals
• Video Input connector 1:15 pin D-sub high density male; VGA
compatible Analog .7 to 1volt level with 75 Ohm input.
• Video Input connector 2: 10 pin connector Analog 2.2 to 4 volt
level at 250/350 Ohm; CGA/EGA 0.156 center header.
• Sync type: TTL & Standard CGA / EGA / VGA/ sync (positive or
negative).
• Sync input: Separate or composite sync from 1 volt to 5 volt input.
• Sync Input Impedance: 2.2K Ohm (H sync and V sync)
• Horiz. / Vert. sync frequency: 15.75 to 40 KHz / 40 to 100 Hz.
Attached you can see that TTL input which can take up to 4V. I measured the voltage between R and ground coming from the board and it gives me 4.9V. I was worried about that but the person I was speaking to said that's with no load, it will drop when it has one. So the voltage seems ok, that leaves me with the Ohms question...
The specs say it should have 250/350 Ohms, how do I know if that matches what my Model 2 gives?
