I have switched in recent years to screw terminal DB9 adapters where DB9 connectors are required. I used to use the RJ45 to DB9 adapters but the pins are a pain and the housings can be too big in many cases.

The nice thing about screw terminal adapters is that you can quickly swap Rx and Tx if needed. Given the lack of good or consistent documentation from manufacturers, half the time it is a crap shoot if the device is straight or null. This way... who cares... it takes seconds to swap them.

Also many control manufacturers have gotten smart and are using screw terminal block, 3 pin jack, or RJ45 serial outputs with solid documentation on the pin outs.

If you make up straight for your end point female ports and Null for your end point male ports you will will have a high rate of success and when you don't get it right... so what.

I do the same and use the connectors from BTX. I believe they're called MaxBlox. Hell of a lot easier working with these, especially on commercial TV's.

I will still use the RJ45 Adapters in racks when both devices have a DB9.
