RXD and TXD labeled wrong on JYE119

The manual correctly shows pin 7 as RXD and pin 6 as TXD for JYE119 Uart-USB converter. The board, however, has pin 7 labeled as TXD and Pin 6 as RXD. This caused me to hook it up wrong when I tried to upgrade the firmware on my DSO Shell. I'm sure it is creating problems for a lot of other people as well. The picture in the manual, and the picture in DSO Shell: How to Upgrade Firmware, both show the correct way to run the wires. My part number is 109-11901-00A.
Also, it sure would be nice to see the JYE119 with a micro USB connector, as the mini USB cables are getting scarce.

We admit that the labeling on the 119 board does create confusion due to the board was originally created for DSO068. It is suggested to follow the drawing given in http://www.jyetech.com/Products/LcdScop ... rmware.pdf . Yes miniUSB is getting obsoleted. We might re-design a general USB-Uart converter board with microUSB.
