The USB Mini-B Port is the programming port you can use to connect a PC with a
USB host port using SoMachine software. Using a typical USB cable, this
connection is suitable for quick updates of the program or short duration connections
to perform maintenance and inspect data values. It is not suitable for long term
connections such as commissioning or monitoring without the use of specially
adapted cables to help minimize electromagnetic interference.
WARNING
INOPERABLE EQUIPMENT OR UNINTENDED EQUIPMENT OPERATION
You must use a shielded USB cable such as a BMX XCAUSBH0 secured to
the functional ground (FE) of the system for any long term connection.
Do not connect more than one controller at a time using USB connections.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
The communication cable should be connected to the PC first to minimize the
possibility of electrostatic discharge affecting the controller.
