Solution:
The BB/Quatech XSU-400 series USB 2.0 products are the compatible upgrade to the USB 1.0 based XSU-200/300 series with one minor change. Since the 400 series add MEI (RS-232/422/485 selectable per port), their pin out differs from the 200/300 series. For existing customers to maintain compatibility on the connector and use existing cabling, the DB9F-400C adapter should be requested. For the new pinout please refer to your User’s Manual.
