Find out connection settings?

[niko001]

Hi,

I recently bought a POS-system (Flytech POS 360) that came with a customer VFD. It connects to a serial port, but I am having trouble getting it to display anything. It did not come with any drivers (the website lists a USB2COM bridge driver, but since the display already connects via COM, I believe that this driver is for a different model). I've tried to connect via HyperTerminal, but don't know the COM-settings (I've tried multiple, such as 9600,8, no parity, 1 stop-bit, hardware-control). When using LCD Smartie with the test-driver-plugin, the VFD stays black as usual, i.e. nothing happens.

Is there any way that I can find out the COM settings other than manually try each possibility? The back of the device says "smartTOUCH310x-REAR", which I have obviously googled, but the search does not return anything. The manual of the POS only says that it comes with a VFD, not how to control it.

Thank you very much for your help!

Best regards,
Nick

Customer displays usually use a few commands to get them to turn on. I have a lot of customer display, and the two models I have use two different lines of HEX code to get them to work. . . However they are all the same baud rates and what not. 9600 baud, 8 bits, 1 stop, none flow control, none parity. Now get a program that access the com port, I think the terminal thingy works too. You need to try and find the datasheet for that display because there is a list of HEX commands that you will need to know. For mine, one is 1B 01 for reset, wihch clears it, then I send 1B 02 to erase any junk that is on the screen if any, then I send 1B 05 to turn the display on, then after all that close the program, then open smartie with the test driver and go from there. . . I don't know if those commands will work for you, but give them a try. . . My other display set is as followed, I clear the display which is 0C then turn it on which is 1B 40. Now I don't have to manually do this anymore because there were special display drivers made for me by looking at the datasheets. . .

You may also want to just search the brand name and the "class" number for that display on google, and it might bring up some kind of PDF datasheet with all the commands in it. . .

Thank you very much , I was able to find the data sheet and it was indeed exactly as you described (Hex-commands to turn the display on/off).

Thanks again!

No problem mate, I'm glad that I could help you out I know when I first started off with these customer displays, I needed a bit of help beacuse they are a whole different story then a traditional LCD display lol.
