RS-232 Set UpBaud Rate
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.
To change the baud rate of the matrix or the receivers (i.e. AT-PRO2HDREC or AT-PRO21616M-RX)
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 and
the output baud rate is for control of the RS-232 device in the zone being altered.
Note: Baud Rate must be only 2400, 4800, 9600, 19200, 38400, 57600, or 115200
