RS232 is for interfacing to a PC via a straight-through DB9 male to
female cable, and operates at 9600 baud, 8 bits, no parity, and 1 stop
bit.
USB Connection: To use the USB port on the USU, a virtual COM port driver must first be
installed using the driver CD-ROM shipped with the USU. This virtual COM
port driver will create a new COM port that will use the next available port
number. For example, if your PC has two COM ports, the virtual COM port
driver will create a COM3 port. Follow the instructions on the CD to install the
driver.
