External power connector

Although the USB-1616HS-2 is powered by a USB port on a host PC, an external power connector may also be required to provide sufficient power for the USB-1616HS-2.

Connect the optional TR-2U power supply to the external power supply connector. This power supply provides 9 VDC, 1 A power to the USB-1616HS-2.
