Set Up
To set up the RS-232 hyperterminal (if not using 3rd party software) use the following steps:
1. Connect the matrix to a PC using a 9pin to 9pin cable
2. Go to the Device manager folder (see picture A)
3. Find the Matrix COM port and right click with a mouse and select properties (see picture B)

will disappear and reappear on the COM port list.
