I sell connectivity kits for the vintage Apple II family of computers to connect Apple II computers to PCs and Macs, By bundling this connector with a standard serial cable, the customer gets multiple usage from the kit. They don't need to have one serial cable and one null-modem cable, thus reducing cable clutter. Customers prefer this thin adapter over the bulkier, larger adapters.
PROS: Thin profile means less protrusion from the socket & therefore less chance for accidental bumping/damage
Less bulkier than other null-modem adapters (reduces shipping costs)
If the one trick the pony knows is talking, then it's a pretty good one trick. Thats how I see this DB9 adapter. Doesn't do a wide variety of things, but the one it does, it does it well. I had bought some serial cables instead of ordering the null modem cables like I knew I should. These little connectors come to the rescue. They work as intended and a well built. Ya gotta have on of these in your toolkit...
I would/will purchase these again.
PROS: Well built, very cost effective, and does what it says it will do....
A great adapter when you're not sure if server equipment is expecting a standard or null-modem serial cable. Solid construction and worked fine for me. The provided screws were easily removed which allowed me to connect it to the cable I had.
