USING RS-232 CONTROL (continued)
NOTES:
 When successful, commands #1-5 will acknowledge by sending the
checksum with nibbles swapped & <CR><LF>
e.g. checksum of 0x24 acknowledges with <0x42><CR><LF>
 All bytes in examples are ASCII characters unless they are contained in
brackets <>
 Calculating the Checksum: <CHK> stands for CHECKSUM: the <CHK>
value is calculated by performing an XOR of the full command string
*For example: //F00M12I03 will XOR to the hexadecimal value
0x42, therefore the value of <CHK> is 0x42
 <CHK> is the logical exclusive OR (XOR) of all previous bytes.
 <CR> is carriage return (0x0D), all commands sent from PC end with
<CR>.
 <LF> is line feed (0x0A)
 xx is the frame address of the router e.g. “00” or “01”
From the factory the address is always “00”, however it can be changed
with command #5 above.
 yy is the Output (monitor) number. e.g. “01”
 zz is the Input number. e.g. “06” or “16”
 nn is the Matrix’s new frame address
