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)
NOTE: If unsure which COM port is the matrix, unplug the 9pin cable and plug it back in. It
will disappear and reappear on the COM port list.
4. Under the properties menu select the port settings tab and update the menu to the matrix
default settings of: Bits Per Second: 115200, Data Bits: 8, Parity: None, Stop Bits: 1 and Flow
Control: None. (see picture C)
Set up is done and any hyperterminal program may be used to control the matrix now.
