Problems with HD44780 Parallel

Hi,

I recently purchased this display. It came with a parallel/molex cable so all the wiring was pre-done.

20x4 display

When I first switch my pc on, the display lights up and I get two rows of white squares (I think this is normal).

I installed the latest LCDSmartie software and the port95nt drivers but I can't get it to display anything. I have tried setting the 'Timing Multiplier' to 1 and 5 but no luck.

The BIOS parallel port settings are set to EPP 1.7.

Am I doing something wrong? Do I need to change any other settings in the Device Manager?

I have also tried CrystalControl software but all I get are garbled characters. Also tried LCDCenter with a bit more luck, I initially get some words and characters but then it gets garbled.

Any ides?

Check your wiring against the diagram on the website, I think there is one in another HD44780 thread.

Thanks for the reply.

Unfortunately the cables/wiring were already done by XSPC I guess. If I take it apart I might invalidate the warranty and not be able to return it.

I've had a chat with XSPC support and after trying it on two different PCs, it seems that the unit is faulty, so I will have to return it.

i had the same problem i had to change the port number.
Port: the address of your parallel port (usually 378, but 278 and 3BC are also common). think i had to use 3bc to get mine to work.
