Default SCVDOC1 Questions about Power

I'm having problems with my stiletto recognizing power and I never see it charging in this dock.

I'm confused over the wiring DIN CABLE Pin Connections that are included in the manual.

Should the +5V of the stiletto Power adapter go to Pin 1 or Pin 2?
Should the -5V of the Stiletto Power adapter go to Pin 4?

Thanks for your help.

Mike

I would probably thing 5VDC should go to pin 1 and ground on pin 4. The power enable is probably to let the radio know its connected to a device.

Well I'm not so sure the diagram is correct.

Currently I now have my Mitch's MJS Gadget box working. To get it working I had to use 12V to this box I had an issue that I first used a 300ma power supply and the Sirius Connect interface on the stiletto kept rebooting over and over. When I got a 1000ma adapter it now works fine. I was concerned that I knew the stiletto used 5 volts not 12, but the SCVDOC1 must drop the voltage down.

If I ohm out the connector there is no connection between the Pin 1 and the tip of the power adapter, nor does the ground to pin 4.

Once I connect the 12V power and the USB cable to the PC, I measure the voltage at power plug of the base of the dock and its 5.18V.

If I connect the dock to the stiletto with no battery it will power up. So I know its getting power.

Measuring the voltage of Pin 1 from mitch's box it measures 5 volts.

I also followed the diagram to connect the dock to a headset and at first it did not work. I ohm'ed out Mitches device and found that Pin 6 is Audo Right and Pin 3 is audio left. Its like someone who made the manual was looking at the connector backwards.

So, Now I have the Sirius Recorder working on the computer connected to the stiletto.

I also have made another cable that will enable me to connecto my SCVDOC1 dock to the stiletto and without any power, connect to a headset and speaker and to an antenna. The same as the portable antenna cable. The one thing I still cannot do in this mode is charge the battery.

I really wish we could get some technical information about this dock!

What Sirius-Ready or SAT-Radio ready headunit + SiriusConnect interface are you using? The Headunit interface should take care of all the power requirements.

FYI- PIN 1 is the main power line and should be 12volts
PIN 2 is called the "Power Enable" line and is what tunrs on the unit- if can be 5v ~ 12v to tunr it on.

When the SL unit is in the dock, and connected to a headunit/interface, the Stiletto goes into 'SiriusConnet' mode. for a Stiletto 10 or 100 to work properly it needs to be updated to the latest verrsion of software - ZAP= 1.1.1.5.3031r and the OS needs to be 1.1.0.43757

Actually I'm not using a headunit. That was the issue. I now have it working with Mitch's SC-C1 MJS Gadget box connected to my computer. The Sirius Connect device is the SCVDOC1 dock to my stiletto. Normally this box is connected to a Sirius Connect SC-C1 box. That box comes with it's own 12 V supply. The SCVDOC1 box has no 12V supply.



I was using 12 V to mitch's box. This 12V supply according to Mitch is passed through directly to the DIN connector. The issue was my 12V AC adapter was only 300ma. Apparently this is not enough. This weekend I exchanged it for 1000ma and now the radio goes right into Sirius connect mode. It had been going into the mode, then would reboot cycling between these two states.

One thing that I noticed with this SVCDOC1 box is that you can connect an antenna to it and without any power supplied it will let the stiletto use this antenna for reception. This is different than all the other docks. With all the other docks you need either 110 or 5V applied to the dock to be able to use an external antenna.

So I was able to use the dock, with an antenna, and connect a earbuds or portable speaker and remain totally portable. In the non-sirius connect mode, I control the device through the stiletto menus and buttons. Now here was the issue, IF I wanted to charge the battery, I thought I might just be able to supply 5V to the DIN connector and it would be passed through to the dock to charge the battery.

It seems not. The only way this dock will charge the battery is to be in Sirius Connect mode and supply both 12V and a Serial signal. At that point the SCVDOC1 Box does somthing to reduce the voltage and supply power to the connector plugging into the stiletto.

Thanks for the FYI on the voltage.

My plan is to be able to control the box with software on the computer.



I now have Alex's Sirius Recorder program working, but I would like to be able to code my own. Do you have any information on the protocol and the commands to send via a complient sirius connect adapter to control the unit?

Anyway, I made progress, with the Sirius Recorder program working. My own DIN connector will work with the SCVDOC1 dock with earbuds. I'd also like to figure out the remainder of the DIN connections and find out what it takes to connect a normal serial connector ( RS-232 ) to the TTL serial connections in the SCVDOC1.

Again thanks for the information on the power.

Mike

Mike,

I am trying to use the same setup just to listen to my Stiletto in the car (ie. no data interface just audio and power). The SC-VDOC-1 gives a compact install compared to the giant car kit which is why I am going to this trouble.

I am trying to figure out charging. You said:

"So I was able to use the dock, with an antenna, and connect a earbuds or portable speaker and remain totally portable.

I don't want the unit to go into Sirius Connect mode, but do want to charge the battery. I was wondering if you tried just supplying 12Vdc to Pin 1 (battery) without applying it to pin 2 instead of 5V. It looks like you only tried 5V to pin 1 which didn't work or did you try that and it didn't work either.

Thanks in advance.

Rob, I've tried 12V too. It seems that with this dock, the Serial port must also be active as well and once all this is in place, the radio goes into SiriusConnect mode and then voltage is appled and the unit begins charging. It seems that there must be some switch in the dock that the software in the dock triggers to make this happen. I do know that the radio will work in the dock in Sirius Connect mode without a battery I tried this as well. But whenever it is not in sirius connect mode it can only run in portable mode but it does allow for connecting to an external antenna and it will drive a speaker or earphones. No other docks allow this. They all need to be powered to use an external antenna.

I guess I could take the dock apart and see what it would take to apply 5 volts to the connector directly, but I don't really see the need because franckly If I have 5V I would use my home dock directly and that would work fine for me.

So after much delay, I'm back to this project. I tested the power plug on the SC-VDOC1 with 12V applied to the 'battery' and 'power enable' pins. You are correct, this gives 5V to the power plug on the dock (with or without the radio in the dock). If I put the SL100 in the dock it goes into SiriusConnect mode. So, now I am thinking it may be easier to cut the pin that tells the SL100 it is in SiriusConnect mode and then I'm there.

But, so far I have not found much in the way of pinouts for the PnP dock connector. Someone must have this...I can't imagine it is that proprietary...

Since this project, I have figured a way to get the radio to switch from the internal to external antenna. There are two latching 1K resisters that go from the pins to ground. I've done this using the universal connector that plugs into the bottom of the stiletto. Here is the pin-outs.
If 5V is applied to the power connector it will charge at the same time.



As far as using the SC-VDOC doc to do what you want, you might be better to just buy an old XM or Sirius doc and re-wire the connectors.

This is going to be my next project.

I think the two left most pins in your picture are the ones that tell the radio which dock they are in. The pin labeled 'unused' goes high for Sirius Connect mode. I think I can use the dock as I want by cutting this pin. I'll post when I get it all working.

I did verify that the pin connected to the 1K resistor closest to the antenna connector is all that is necessary to tell the stiletto to use the external antenna.

Robert - I'm looking forward to your findings... Please keep this thread updated...
