Hi all, I am generally new to the world of LCD modules - although I do have experience with programming Epson EPOS equipment including display pods so I'm not unfamiliar with them.
I bought 2 634 modules from 'the bay' and am struggling to make any of the test applications work with it.
I'm using a straight through, 9-pin serial cable and when no applications are running connected to the display, on initial cable connection the display shows a boot screen for a few seconds and then switches to a flashing cursor. I am not using any external power at the moment (as for now I do not need it backlit).
My PC port settings are as follows:
and I've modified the jumper settings for the port speed on the back of the module to reflect the appropriate speed.
Whenever I start one of the test applications, the application appears to connect successfully to the module ... forcing the display to be cleared but I cannot make anything else appear on the display.
I've tried using WinTest and CrystalControl2 and both applications, and both displays exhibit the same behaviour. I've also tried using a slower port speed (9600)
Help! What do I need to be doing to get the display(s) showing something different using the test apps?
