I am using a LED display which has following specifications:
TFI-32x128-37RG 4.76mm Tri-color RS232/Ethernet 6.9"x26.22"x2" 4 lines of English
I have connected it to PC com port and want to send data through the port.
But when I use hyperterminal to send some data on the LED board, it is not responding.
Is it possible to send data through hyperterminal on LED board? Or is there any other method to display data on LED board through PC com port?
Presumably, yes, if you're using the right baud and character settings (bits/character, parity, stop bits). However, the interactions between Hyperterminal, RTS/CTS, DSR/DTR, and the LED board may also be an issue. You might want to try TeraTerm
I assume you've reviewed the documentation available at
As Rich wrote, you need to find out what baud rate, start/stop bits and hardware handshakes this display expects. This information should be in the booklet that came with it or maybe online at the manufacturer's site.
Not to spoil the broth here but there can also be electrical discrepancies. For example one of the laptops here has a hard time driving some RS232 devices. A voltmeter revealed it: The laptop only sends a 6V level and some devices don't seem happy with that (although per standard they should).
How about RTFM:
