x1AVx2,x3,x4	x1AVx2,x3,x4	(input 3 = x3AVx1,x2)
		(input 3 = x3AVx1,x2)
ARConY	ARConY	Enable ARC on an Output. Ex. Output 2 = ARCon2
ARCoffY	ARCoffY	Disable ARC on an Output. Ex. Output 4 = ARCoff4

ARCsta	ARCon1,ARCon2,etc	Displays all ARC output status

Mreset	Mreset	Sets matrix back to the default settings

RS-232 Set Up

To set up the RS-232 hyperterminal (if not using 3rd party software) the first thing needed is to find the RS-232 communications port under the computer’s device manager. Once there right click the port and select properties. Under the properties menu select the port settings tab and update the menu to the matrix default: Bits Per Second: 115200, Data Bits: 8, Parity: None, Stop Bits: 1 and Flow Control: None.

Baud Rate

To change the baud rate of the matrix an RS-232 hyperterminal will be needed. Once the RS-232 hyperterminal is set up changing the baud rate will be done with a command line. The baud rate for the matrix is for matrix control.

Note: Baud Rate must be only 2400, 4800, 9600, 19200, 38400, 57600, or 115200

Command for Matrix baud rate

CSpara[baudrate,data-length,parity,stop-bit](data, parity, and stop for matrix must be 8,0,1)

For example if you wish to change the baud rate to 38400 the command would look like this:

CSpara[38400,8,0,1]
