Package List 1X PCIE-SE2 1X Mini CD 1XUser Manual 1X Mount-Screw 2X Low Profile Bracket Review: Works as described - Works as described Review: Works with legacy equipment even when USB serial ports don't. - I have been trying to get the CAT port on my old Yaesu FT-847 working for some time now. Putting a scope on the Rx pin of the radio I noticed that the levels seemed very low at about 3 volts. This was using a USB serial port CAT cable purchased specifically for this radio. I thought why not try a more traditional serial port and ordered this product. Installation went smoothly and my Windows 11 PC soon showed two new serial ports. Connecting one to the radio with a F-F null modem cable and initialized everything at 4800 baud. Bang just like that the CAT port lit up and started working. Looking at the levels on the scope, they are more like 10 volts now. ## Features - 1.
