Need some help getting a lcd to work on a infoblox Trinzic 1400

stephenw10

That looks like a USB header. Does the LCD normally connect to that?

What is the LCD?

Steve

stephenw10

Ah I see that it is. In which case check what ports actually exist in /dev. It may not be USB serial.

Here are the devices:

I will be opening the box up to see if I can determine the manufacturer of the LCD. (Thanks for the help)

stephenw10

Ok, so cuaU0 is a USB connected serial device so it's probably the LCD module unless you have something else configured there.

Try running usbconfig dump_device_desc

That will at least show you what USB/serial chip is in use. To know what driver to use though will probably require some visual examination.

Mmm, OK so looks like it might have a separate USB input device for the buttons.

Yeah, you'll need to try to get some more info from the LCD module itself.

Attached some additional information and pictures I found on ebay of a similar/identical model (pictures show B0478 and mine is B4985 but all connectors are the same):

PM8664 1351IB4985
219-0001-000 REV10 SW 0.53

The LCD documentation can be found here -

Is there a suitable driver in pfSense?

stephenw10

Probably not. That looks like a PIC controller which could be running some custom code. It might require a significant reverse engineering effort.

Try disabling lcdproc and opening the USB serial port at the command line. You might at least be able to determine the serial baud rate it's operating at which would help you test other drivers. There might be some other clues there.

It looks like what would matter to a driver is this PIC24 from Microchip, listed here:

PIC24FJ256DA210

"The PIC24F-DA family features integrated graphics acceleration and a display controller to directly drive displays up to 4.3" WQVGA with 480 × 272 resolution. Ideal for Graphical interface applications that can benefit from the integrated Graphics, 96K byte RAM for frame buffer, mTouch, USB and other peripherals."

This looks more like a full blown mini graphics card over USB...

stephenw10

Well.... that could be fun!
