Hi,
I need some help here .. I want to connect a
Fujifilm EXP-2500 to a raspberry Pi, in order to save pictures taken with the EXP-2500 on a hard-drive.
The problem in this topic is the communication with the EXP-2500 : I've got 2 options : first of all, a 2wires cable that sends a signal when I need to capture an image. Using this signal in the Raspberry Pi wouldn't be too difficult, but I would prefer the 2nd option : The Endoscopy Processor (EXP-2500) has got an option for serial communication with a printer. I already managed to connect a computer to the serial port, but when I try to "print" an image with the EXP-2500, it only sends my computer a few bits (248 I think), two times the same ~128 bits sequence. But after that nothing more, except a message on the EXP-2500 annoucing a time out error while communicating with the printer.
It looks like the EXP-2500 is sending the beginning of a protocol to the computer, but as I am too young to know how RS232 printing was supposed to work, I'm here asking for help.
The EXP-2500 is able to communicate using the RS-232 port to 3 different devices : two Sony printers (a Sony UP-51MD printer and a UP-25MD if I remember well, and to device called "CP900" -no more infos about this one.).
What I need here is the protocol used by these printers, so that I could emulate the behaviour of a printer with the raspberry Pi. Once I have it, I'll be able to get infos form the EXP-2500 way more easily as if I take the first option (in which case I would have to use a text recognition software to get the patient's name anf other infos...)
I hope my question isn't too specific and that it is explained good enough for you to help me!
Thanks in advance
Clément
But thanks already for the manual, it has some important baud rates (for the COM port) settings.
And if someone had an "how-to" explaining RS-232 printing, or a driver designed for the printers I mentioned before, this would be really great!
