7.6 Communication Port

The main logic circuit board contains a standard type B
USB communication port for PC connections and a USB
host connector for a mass-storage device connection.
See Figure 7-9 and Figure 7-10. See Section 7.13.12 for
USB flowchart information. Refer to the List of Related
Materials in the Introduction for corresponding SiteTecht
software and/or communication installation information.
Note: Before inserting a mass-storage device (USB host
connector), power off and then power on the
controller.
See Figure 7-8 for tested/approved manufacturer's
