Hi all,

Hope I can get some more info on the screen here. What we're looking for is a screen solution with indicator LED's and a few buttons that will work with our in-vehicle telematics box. We only have an RS232 port available on our box for comms to the screen.

The GLK19264-7T-1U-GW seems to fit this need. What I'm not sure of is if this will work with our box.
Is it just a matter of sending and receiving characters over the COM port in order to control all aspects of the screen?

We have done some initial developments with another serial LCD product from C**********z (CFA635 Series Serial LCD) which seems to work OK. Obviously we would like to explore all options before settling on a specific one.

Also if anyone has any suggestions as to whether enclosures for these screens are available.

As an example, would the following C# code, with the neccessary modifications in terms of command structure and what needs to be sent etc. be enough to get talking to the screen?

--------------------------------------------------------

private SerialPort Port = new SerialPort("COM1", 115200, Parity.None, 8, StopBits.One);

Port.Open();
Port.Write("whatever is needed to be sent...");
Port.Close();

-------------------------------------------------------

Thanks in advance,
Fanie

Hello Fanie,

Thanks for your post.

And also, thanks for considering our GLK19264-7T-1U display.

The GLK19264-7T-1U should work nicely with the RS232 output of your box. Yes, it is a matter of sending data to the display in order to display text and graphics on the screen. It also has neat built-in graphic functions like line drawing, rectangles, bitmaps and strip chart.

The LEDs are built in general purpose outputs that you control by sending commands to the display. The built in keypad is very handy in that you do not need to make extra connections to a separate keypad.

As per enclosure, I have no recommendations, but I suggest that you check out this mounting bracket.

Your code should work with minor addition:

Code: Select all


private SerialPort Port = new SerialPort("COM1", 115200, Parity.None, 8, StopBits.One);

Port.Handshake = System.IO.Ports.Handshake.None;

Port.Open();
Port.Write("whatever is needed to be sent...");
Port.Close();

I hope this helps. Please let me know if you have more questions.

Best Regards,
