OBi110 hardware
VirtualMonitoring:
I am looking into different ways of integrating other devices with the Obi110, so it was out with my screwdriver to have a peep under the hood. I spotted a couple of connectors. JP4 has 8 pins and the other one had 4 pins. Here is an image of JP4... http://www.ipalarms.net/image/jp4.jpg for anyone that's interested.
Can anyone at Obihai let me know what either of these connectors, or indeed the jumper switches are for?
I'm secretely hoping for an input or output which would allow me to use the device in a special application I have for it ;D
Dav3yDark0:
I opened mine as soon as I got it and took some hi res pics. I tend to tear into most things I purchase.
JP1 appears to be an RS232 serial interface.
JP4 appears to be a JTAG interface.
I haven't played with either yet, I really need to get another 110 just to play with so that I don't interfere with my current phone setup.

I'd be very interested to hear anything more on this subject.
Dav3yDark0:
As I said, I haven't played around with the JTAG or serial port.
I suspect the JTAG port is for firmware writes if bricked, monitoring RAM or other registers for debug purposes, etc. There are a number of free and/or open source JTAG utilities around, will need to figure out things like processor and flash brand and models to figure out some of what you need to send through the JTAG port to get results.
The serial port is most likely to connect a terminal or terminal application to to have access to the OBi devices console.
When I have some time I will play with it, but I might wait until I can pick up another one to play with when I have some extra cash.

Been able to find any time to fiddle yet?
