Is the 1784-PCMK card still available? Trying to order a new one from AB and they are telling me I need a 1784-U2DHP data highway to USB interface.

No, I have been told that they (A/B) discontinued it.
Try Ebay

What is involved using this new replacement card they are recommending? Are there after market replacements for what they are replacing the PCMK card with?

I have not used one yet, luckily we have two of the 1784-PCMK cards and relatively new laptops. The 1784-U2DHP is USB to DH+ (No support for DH485...that'$ another cable) and it comes with the mini din connector on the end, so you might need another adapter, depending on your application.

Here's an installation manual for it that should help you:

Yeah, they're expensive.

Depending on your needs, it might be worthwhile to set up a Controllogix Gateway (Logix chassis, power supply, ENBT card, and DHRIO card) and then be able to access your DH+ nodes using ethernet.

If you need something portable, then go with the new cable...

1784-u2dhp

Well, they're the same price as the device they replaced. Plus RA offers a discount (40%, last time I checked) if you trade in a 1784-PCMK. And they work with the excellent Frontline Test Equipment NetDecoder software.

They're not cheap but they are useful.

I do agree that they ARE useful, unfortunately do to cost many of us won't experience it.
