USB to Serial RS232 Adapter, Stand-off nuts

We use this USB Serial Adapter to communicate between a Toshiba laptop and Yaskawa (Yasnac) i80M, Maho (Philips)CNC 432, Fanuc 16T, and Fanuc Power Mate CNC controls. It works great. The other adapter I used (Radio Shack) was recommended by DNC software maker, but it often gave the "blue screen of death" and we had to unplug and plug in the cable between each file transfer.
