Alternatives to PCI KT Card for DH+ coms on Win7

We are upgrading a Wonderware Intouch 7.0 SCADA system to Intouch 2014 R2.
The current system runs on NT4 and uses wonderwares AB1748KT IO driver with a PCI KT card to talk to a PLC5/30 and a SLC500.
We need to find a replacement for the KT card for DH+ coms and a new IO driver/server. The new machine is an IPC running Windows 7 Untimate 32bit and has already been purchased but has no PCI or even PCIe so we limited to either USB or Ethernet.

I was considering using ABs 1784-U2DHP USB to Data Highway Plus Interface with kepserver but looking more into this its DF1 to DH+ and we are worried about bottle necks in the com's and update speeds.

So I'm now looking at Ethernet to DH+ bridges.

Has any one used the following product EQ7000 and have any comments.

Thanks

Do not worry about this. The performance is similar to a PKTX card.
One issue with the U2DHP is that its interface is an 8-pin mini-DIN. So it has to be nearby a PLC5 or SLC5/04 to transition to the blue cable. That, or you manufacture your own adapter from 8-pin mini-DIN to 3-pin Phoenix connector (if someone knows of a commercially available adapter I would like to know).

Just found such an adapter cable (from GiT's site):

I did this cable to get to terminal block. Don't supose any one has the pinouts to make this cable up.

Looks we are going down the ethernet bridge root with this product and use it with wonderwares ABTCP DAServer as per their user guide.

See pdf

The DASABCIP is a very stable way of communicating DH+

to the SLC's and PLC-5's with Wonderware. Just remember

to add your access name to your device groups in the

DA server for your tags in WW.
