E-2000 Dip Switch Settings

[sudsy7]

I'm trying to figure out what dip switches settings 2 and 3 do on my E-2000.  Can't find them in the manual and they don't seem to affect the game whether they are on or off.   The others function like this:
1        Reel Spin Sound ON or OFF
2        ?
3        ?
4        Attract Sound (after approx. 1 minute of no activity) ON or OFF
5        Attract Lamps Flash (after approx. 1 minute of no activity) ON or OFF
6        Flashing Lamps ON or OFF
Any ideas?

dip switches 2 & 3 might not be used in your machine. Not all dip switches were used in every machine.. There should be a list of settings on the back wall between the MPU and the IO boards..

There is a label in the back of the machine but it only has info on switch #1 (jackpot bell and gong), which no longer applies because the machine was converted to sound.  It also says switch 7 is not used and switch 8 must be on for game operation. 

I can't think of anything on this slot machine that switches 2 and 3 would control (and I don't notice anything different in game play regardless of their position), so they probably aren't used like you say.  I just wanted to run it past a gallery of experts in case I was missing something! 

Thanks for the quick response.

The label in the machine only lists the dipswitches that are implemented in your machine software. So, if a dipswitch is not mentioned it doesn't do anything. Dipswitches 1,2,3,4,5,6 are all read by the mpu game software if the dipswitch is utilized.

Dip#8 enables or disables the mpu reset circuit. You want this set to ON for normal game operation, OFF setting is used when troubleshooting the mpu. Dip#8 position does not matter if jumper S1 on E-2000 mpu boards is installed (S14 on E-1000 mpu boards), since the jumper permanently connects the Dip#8 switch circuit ON anyway. A tech would remove this jumper if he needed to set Dip#8 OFF. S1 is located near the dipswitch on E2000 mpu boards.

Dip#7 is not connected to anything on the E-1000 or  E-2000 mpu so it can never be used unless a mod was done to add wires to it.

The unused switches were in case of future use on different game software but were not implemented as far as I know. But there are a lot of different gaming jurisdictions and different games out there so there might be a setting for an option in some machines somewhere, Bally sold their machines all over the world.
