Help with DCI Install
On the DCI-2 DIP switches it says switch 1 is the "Mute Control" in the instructions, but in the illustration switch 1 is "Tap-n-Press." What is switch 1?
Also, in the instructions for the Mute Control it says turning the switch ON activates hard-wired mute function for HU's that have ATT or CELL PHONE wires, and it gives improved mute function. It then says, "If you prefer this feature connect the DCI to the CELL PHONE or ATT wires and set the switch to OFF." Should the DIP switch be set to ON or OFF if I do want the improved mute functions? I don't have an IR emitter and I am installing the hard-wired DCI module. I have the Alpine CDA-9887.
Lastly, when connecting the SCV it says to run a wire from the "Grey DCI cable" to the "Speed Signal wire." Just to be sure, is the "Grey DCI cable" the same wire the 3.5mm plug is a part of?
Thank you

Sorry for the confusion, I recently shipped some DCI's with hosed-up instructions for the dip switches. Depending on which version you have it may have a good drawing and bad instructions or they may both be bad.
This should be correct if you have DCI version .408:
Switch 1 is Tap-n-Press. Flip the switch ON to activate Tap-n-Press.
Switch 2 is Mute - If it's ON the mute is sent via the 3.5mm cable (this is not considered a wired mute function because the mute command is sent via the same method as all other commands). Setting the switch OFF sends the mute command on the DCI blue wire, which connects to the Cell phone or ATT wire on the head unit. This is a "wired mute" because it's a dedicated wire that only does the mute function. It will pause CD playback, where the other mute usually doesn't.
The DCI "gray wire" is not the 3.5mm cable. It's a separate wire (as shown on the color wiring diagram) that is provided on the "regular" DCI harness but is optional on the PnP harness. If you have the regular harness the gray wire must be extended and connected to the speed signal using your own wire and connectors.
I figured people who buy the PnP harness want it as simple as possible so I made an SCV kit that has the gray wire (long enough to reach the speed signal) with the connectors already attached on both ends and a T-tap to make the actual connection. Since this kit costs a couple dollars I made it optional so those that didn't want SCV didn't have to pay for it.
