"Problems with A-B 1784 KT Card"
We have recently upgraded/replaced our workshop pc (from a pentium 133Mhz & 32Mb Ram to a pentium 3 667Mhz & 128Mb Ram) and transferred the ISA slot 1784-Kt card from the old pc to the new one and it is not working. We are confident the card is set up ok (ie DIP Switches & IRQ's jumpers) & the new pc is ok. Has anybody else had problems with an old ISA card in a newish fast pc?? (I am trying to avoid purchasing a new PCI slot card)

We ran into a similar problem, and your aside provides a hint that you have the same one. We put a KT card into a new PC that didn't have a "real" ISA slot, but a daughter board off of a PCI slot. That doesn't work. We tried everything you did, even confirming that some ISA cards (like an old ethernet card we had laying around) work in that ISA slot, but not the KT. We eventually were forced to buy a PKTX. Sorry.

Ensure that in the BIOS on the new motherboard that the IRQ you are using is set in the PCI PNP area of the bios. You may need to specify the slot uses a specific IRQ, or change the IRQ to legacy instead of auto / pnp, etc. What make is the bios?

	Also, verify that you have the 1784-KT Series B (1784-KT/B). Allen-Bradley came out with the series B version of that card primarily because the series A was having difficulties with faster computers (Intel 486 at the time). Like previous posts mentioned, newer computers only have 1 or 2 (in most cases today, zero) ISA slots and to get those ISA slots working correctly sometimes takes a little tweaking of the BIOS of the computer. Most computers are set up to automatically allocate resources for the PCI slots and sometimes that can lead to conflicts with a card located in an ISA slot. Also where cards are placed in the system can make a difference. Sometimes putting a card in a particular PCI slot means you cannot use an ISA slot. It sounds like you need someone familiar with BIOS tweaking to come look at your computer or you'll need to read up on BIOS settings. OG

	This is a common problem. You might want to give the factory tech support a call at 440-646-6800. BTW: I got lucky, my series A works fine on my Pentium 2. Good Luck, Shawn Tierney, www.shawnmichael.com Eagle Electric Supply Company, www.eagleweb.com

	This is why we now use the 5/05s instead of other processors. Sure, the cpu is more expensive, but a nic is a whole lot cheaper than a KTX or even a knock off, so it actually costs less to use ethernet. On a side note, when wiring a DH+ network, must it always be daisy chained or can you use a star topography?

	Thanks to all that replied. I finally contacted Rockwell in Oz (where i am) & confirmed that this is a common problem & only solution is to upgrade to the PKTX card. (Something to do with the bus speeds of the newer motherboards) In addition to the pentium 133Mhz (mentioned above) pc, we also have a pentium 2 with an ISA KT card that works ok, just can't get the P3 to work. Our DH+ is daisy chained throughout the plant, however there is one node that has just been 'T-eed' off and appears to work ok. The DH+ works heaps better than the dh485 network - I can only dream of ethernet
