  • Serial commands outside 4D Serial Commander uOLED-128-G2

    Hi All,

    I'm new to these displays and I think I'm missing something here.

    I can write to the display through the Serial Commander inside workshop 4 and everything works fine.

    As soon as I try and write commands to the display using a terminal program (via either FDTI USB to TTL or the uUSB-PA5-II) the screen saver stops scrolling but nothing happens.

    Where am I going wrong?

    I want to test this before connecting it to an Allen Bradley PLC serial module, via a TTL converter

    Thanks

    It's hard to see what could be wrong, what if you use our terminal program and 'send hex' the same hex codes you see in Serial Commander as a bit of a stepping stone?

    Right com port?

    Right baud rate?
