This example command indicates station number 1, header code WD (update data
memory), data memory start number as 1000 or 03E8 in Hex, data to write as 6500
or 1964 in Hex.
Example program
5 I = 0:FCS=0
10 INPUT "ENTER TEXT TO TRANSMIT";A$
15 I = I +1
20 FCS = FCS XOR (ASC(MID$(A$,I,1)))
30 IF I < LEN(A$) THEN 15
40 PRINT "FCS=";HEX$(FCS);"H"
This program automatically calculates the FCS value when you enter the text to the
PC with the keyboard and shows the result in display.
Note 1: Commands and responses begin with the station no. and header code and
end with the FCS and terminator.
Note 2: Up to 131 characters can be sent during a single transmission. To send a
command which has more than 131 characters, divide it into several segments and
send each of them sequentially.
