FSBUS COM module doesn't works

[adacho]

Hello,
I have problem with fsbus com module. In FSBUS admin program Echo test shows firstly 5 good packets data but next shows errors (different value on red field).

I checked connects, soldering quailty, elements, BIOS and system settings etc.

This elements (List below) are different than elements in instruction because in shop this elements wasn't available:
I have MAX232CPE (MAX232 in instruction)
74HC04P (74HC04 in instruction)
BC558B (BC558C in instruction)

I don't have any idea :( Please help. Why it is does'nt works?

Sorry for language mistakes ;)

Hi,

I just made echo test of my fsbus ng com board. At echo test it send data but it counts error´s too same amount as sended.

My system still works completely I have build 2 IO cards, 2 displaycards, led card, servocard. They all works perfectly but still echo test fails. Just connect some of fsbus cards to your com and i think it will work

Check the connection max232 pin-15 and ground.
The copper line here was faulty.
