Kameleon 6 - 8206, JP Interface?

[cliveports]

Hi All,
complete newbie to all this. Just bought a OFA 8206, and then bought a parallel JP1 cable, after spending ages trying to get it to work I find that the 8206 is a jp1.2 (is that correct?) so my questions are;

Can I mod the parallel cable to work with JP1.2? (If not then anyone in the UK wants it for a tenner then please PM me!)

Which of the Serial or USB cables work with JP1.2? Anyone in UK can supply (or in US who will supply?)

Many thanks!

NO

Read this about cables.

Basically, for the JP1 remotes (read older remotes using P740 and S3C8 processors) the JP1 cables work, of which there are three versions: serial, parallel and usb. The serial JP1 cable does NOT work with serial-to-USB adapters. For the newer remotes that use the HSC08 processor, they use the JP1.1, JP1.2 or JP1.3 (collectively called JP1.x) interface, for which there is only a serial version (Completely DIFFERENT than and incompatible with the JP1 serial cable) which DOES work with some serial-to-USB adapters.

Check the marketplace section for vendors of the JP 1.x serial cables.

Many thanks for such a quick reply Capn!

All understood now, shouldn't have bought the parallel one in the first place! I've downloaded Tommy Tyler's excellent "Building a JP1.X Interface" so guess I need to get the soldering iron out and build myself one.

Just a thought, if serial works with JP1.x then surely it has got to be possible to build a USB i/f that will work with JP1.x? It is, after all, still only data and must be down to s/w drivers?

Off to the electronics shop to buy the bits now!

p.s. anyone got any codes for DBOX2?

Go to the Code Search Forum and read the "Read This First" post. If you can't find what you need in the filie section, then provide the data requested in the Code Search request template.

Yeah, just connect a serial to USB adapter to it!

ah a very polite RTFM!! Thanks once again!

True in theory, the only problem is that nobody has designed such a JP1.x USB cable, probably because it would be cheaper to just buy a factory made USB-serial adapter.

The thing is, to my understanding:

JP1 reads/writes an I2C EEPROM that sits off the microcontroller. That is done by bit-banging (manually turning hw lines on/off, and reading them purely in software), from the lines on the paralell port , the control lines on a real serial port (IR cannot access the control lines on a USB serial adapter), or with the IO lines on a semi-custom USB I/O chip. (I know that for sure, actually).

My suppostion is that JP1.x works entirely different, as it uses a hardware uart (either in a PC RS232 serial port or a USB RS232 serial adapter) to communicate serially to the microcontroller in a jp1.x remote (as opposed to an off-chip EEPROM with JP1).

Which is why JP1 and JP1.x hardware is totally exclusive.
