Title: A4066 EthernetPLUS
Post by: hamtronix on October 05, 2008, 08:17:03 PM
Plugged in my ethernet cable to this card and got the green light but IBrowse gave me a BSD error and I saw no activity on the red light. I know the ethernet is good as I am using it now. Looked up the card on BBOAH and saw this -

Jumpers

The card is shipped for use with 10Base 2 by default

10BaseT:    Shunt JP3 plug OUT
10Base2:    Shunt JP3 plug IN and Shunt JP1 plug into THIN position
10Base5:    Shunt JP3 plug IN and Shunt JP1 plug into AUI position

Do I need to change to a different base to get the eternet working? I am unsure of what the bases mean so any info would be appreciated.

The normal ethernet cables these days are 10Base2 (I very much doubt you have coax==10BaseT)

So make sure to check the jumpers for the 10Base2 setting

You need you know which form of cabling your using.

10BaseT = twisted pair = standard current ethernet cable. http://en.wikipedia.org/wiki/10BASET
10Base2 = thin ethernet = BNC & T piece cable.
http://en.wikipedia.org/wiki/10Base2
10Base5 = thick ethernet = 15 pin D connector. http://en.wikipedia.org/wiki/10Base5


Hope this helps

10Base2 is coax. Those were the days, looking for breaks in a 10base2 network {shudder}

I think that should do it as my jumper 3 was not shorted... unfortunately i just disassembled everything... Will try again later and post from the A4000 if I can get online.

The M26C256B chip on my card is really cool looking. It has a see through window on it. I am guessing its the main chip or something to be pimped in such a way!

You do have your TCP/IP stack online, right? That's what a bsdsocket error suggests the problem might be...

10BaseT is the modern cabling standard.

You know its been so long since ive messed with stacks - i think it was Macs that I even remember fiddling with that - any tips on what I need to run or setup? im on WB3.1

Nope that is an EPROM. The see through windwo is for eraseing it's content by UV-light. Better cover it up becauss normal daylight contains a potion of UV-light as well. So over a longer time the programming of the EPROM could be damaged.

Actually, its just the ROM. Or, in this case an EPROM. The window allows you to erase the contents by placing the chip under a UV lamp, and then you can reprogram it with a different ROM image.

Sometimes it is better to be quiet and thought a fool, eh? Guess its obvious I havent ever 'burned' ... darn there goes my geek cool. well i still have an A4000
