When using the Comm adapter 3 normally, power is received from both the nine pin connector and from the USB port on the computer. Using the Comm adapter 3 normally can cause electrical interference when sending a flash file. Using the power toggle allows the user to turn off the power coming from the USB port to minimize the electrical interference. After this procedure is performed, the Comm adapter 3 will only turn on when connected to machine power. The power supply from the USB to the Comm adapter 3 can be turned back on if needed.
Plug the Communications Adapter 3 into the USB port on the computer and make sure that the adapter is powered on.
In Cat® ET 2013A or newer, select the "Communications Adapter 3 Toolkit" from the "Utilities" menu.
