Sansa E200: Help with remote control
epithetless:
--- Quote from: moxfyre on June 25, 2009, 03:38:40 AM ---The Sansa Base Station offers an infrared remote to control Sansa Players, along with mini-USB and 3.5mm audio out jack. It is $50, which is rather steep in my opinion. To my knowledge, this is the only accessory that offers remote control of Sansas.

With the thought that it might expand this thread's noble pursuit in some way, I just wanted to add a couple more accessories to the list of ones that dock the Sansa and feature remotes:
- Altec Lansing's inMotion iM413 Portable Audio System
- Timex's TS70B Clock Radio
I own the former, but I don't believe there's an easily reversible way to open it up and inspect the internals. I'll give it another look and see if I can come up with anything, though.

Ah! Good to know that there are other accessories offering remote control. Hopefully at least one is easily reverse-engineer-able! 8)

Cool! If you could even figure out which of the dock pins are actually connected to the base station, that'd probably be a huge boost... I've got my money on pins 24-26 being the serial port, based on popping my e200 open and finding visible traces to those pins with no documentation to be found.
UPDATE:
Some material that may help, and for comparative purposes:
* What the inside of the Griffin Powerdock for Sansa looks like (including the seemingly important requirement of a 47k resistor between +5V and pin 7, to enable line-out via the dock connector, at least with stock firmware)
* For comparison, the iPods use various values of resistors between pin 21 and ground to enable different kinds of accessories, including serial communications
* Here's a great guide to the iPod serial protocol, which is basically 8N2 RS232 with CMOS line levels. It links to a pinout showing the dock pins that need to be jumped to enable the serial communications.
I would expect that we're looking for something similar in the Sansa Base Station, or the Timex or Altec Lansing docks with remote controls. By process of elimination, there should be:
* Power connections to pins 1,2 (+5 V) and 3,6 (GND)
* USB data connections to pins 4,5 (USB data +/-)
* Audio connections to 27,28,29,30
* 47k resistor between +5V and pin 7 (likely cue to signal use of a line-out dock)
* Two or three other pins connected to the microcontroller: must be the serial protocol.
So if anyone can look inside a dock with a remote, this is probably what you should be looking for.[/list][/list]

I don't know whether this could be useful. I made a picture of a base station's board. Because i also don't know, whether it is allowed to upload pictures here, i uploaded it to imageshack.
The other side of the board doesn't have any components.

I have just bought Altec Lansing's inMotion iM413 Portable Audio System and would like to get the remote working. so I have a system to test software when someone has a patch to test. ;D
Dark Horse:
Bump? I really would like to get this remote working with rockbox I just don't know where to start . I have a connect that does not respond to the remote but my sansa e200s do in the OF .( I don't have a c200 or a View to test with) Pins for the data cable can be found here:
http://www.rockbox.org/twiki/bin/view/Main/SanDiskSansae2x0PortPins
How can I test pins 24,25,26 to find out if they are an rs 232 data port?
