Quoted from MrMikeman:
Just follow the instructions. http://ledocd.com/usage_gi.html
The board arrives configured for WPC95 which means strings 4 and 5 of the GI are always on. Just change it as indicated in the link.
You can play with the settings to pick a look as far as how fast bulbs turn on and off. I honestly don't remember if I changed settings but I remember trying some different fade delays out. I don't think I changed anything from stock settings.
Remember to go into the pinball settings and enable GI effects and GI dimming. I don't remember what setting number just flip through them. There aren't that many like modern sterns lol.
The machine is sandwiched between 2 others and I don't have an easy access to check the settings I have on the OCD board. I do plan on bringing it in the garage to shop it out and do the cab decals in about a month at which point I can check.
Finally got my GI OCD board installed today.
Its fairly straightforward. The instructions with pictures from the website is all you need.
The default settings pre-programmed on the board are for WPC95 games.
Reading the usage sheet on the website was very informative, thanks for the link!
String 4 and 5 are defaulted to always on.
This means that the board will not control those strings.
You absolutely must enable string 4 and 5
Hit the connect button after selecting the driver that you should have installed earlier (the little Com box will drop down if you click on it and then you can select the driver), allows you to change the setting from "Always On" to string 4 and then string 5.
Once adjusted just send to the board and your done.
No other adjustments to the settings are required, the default numbers are excellent.
I went into the game adjustments and turned on GI Dimming.
then went to the tests and checked the general illumination brightness by moving from 1 to 8.
WOW! what was earlier a spazmodic flickering of unholy hell (when I first built the game a year ago), is now a nice controlled fade throughout the whole spectrum of settings.
The game now "Pulses" with power.
The GI has an amazing faded on and off instead of the harsh, eye-burning flashes it used to have.
In my opinion, I should have put in this board when I first built the game.
Its amazing, and during gameplay does incredible things with the dimming.
Im very happy with this board.
I went with 100% LED's on my game. Some people leave the #906 bulbs in as well as the #89 bulbs.
I think in those cases you are really missing out. LED's are brighter and do a better job without burning up the game from heat.
I think all Doctor Who games with LED's should have both LEDOCD and GIOCD (if you put LED's in the GI).
These boards as well as pinsound with shaker, and the 12 doctors orchestration, put Doctor Who up into the "Must have" games category.
