text appears jibberisch on vfd 2x20

[Ghandi_II]

Hello,

i'am just a beginner in electronics. So i bought a NCR 7402-K455 2x20 Dot Character Display Module Futaba VFD T202DM15AA on ebay.
Beacuse it was a futaba and it was a serial connection i bought this one.

After i connected the tx,rx,gnd and vcc+ to my serial port on a old lcd-smarte v5.0 and selecting crystal com1 56000 baud the text appears jibberisch on the display. Other baud values won't work.

I also tried the smartie 5.4 and latest beta selecting the futaba driver but nothing displayed at all.

Anyone who has the same display and got it work?

wkr,
Ghandi II

=== update ===

I downloaded the hd44780s.dll plug-in.

It's now not garbled/jiberisch anymore.

But the text does not remain steady on the display. In faxt when i put one line text (upper line), the text appears on the display on the up AND bottom line (twice) and both lines scrolls each second 2 positions to the right.
Also a C character (from Curacao) is attached at the left side of the text.

There are some parameters to fill in at startup parameters bu i don't know what timing multiplier, 1x16 addressing and ks0073 addressing means.....

Can you get a datasheet for this module? If so then a driver can be made for it or you can try to use the test driver and make your own. These displays usually use a set of HEX commands to move the cursor throughout the screen and make it work as intended. Cheers
