moin!
das hab ich in einem anderen forum (?) gefunden...
vllt hilft es euch ja mla...
Hello
My English is not so good, but if you just want to find out the
Programm on the A020, I tried the following solution for the A020 for use in my private home:
At first you will need a cable from the serial port of your PC to the A020. My personal experience is that your PC should not be faster than 386/25Mhz because of difficulties with modern serial UART-Chips.
25p (PC) / 25p(A020):
1 / 1
2 / 2
3 / 3
4 / 4
5 / 5
7 / 7
OR:
9p (PC) /25p (A020):
Shield(or 5) / 1
3 / 2
2 / 3
7 / 4
8 / 5
5 / 7
If you don´t own a Software like "Dolog AKL" or "A020fup" you may use a normal Terminal-Programm with the following Transmission codes:
1 Startbit
7 Bit per Character
1-Signal Parity even
1 Stopbit
The Baudrate normaly is 9600. (Possible others: 4800,2400,1200,600,300)
You should get message:
FUS: (OR: *FUS
Type in:
HE (Ret)--------->[Hold A020)
M (Ret)--------->[Show memory)
A020 will sent:
Adr:
Type in (for ex.):1 (Ret)
You will see the program line 1
(For example: 1: UE1 or NO if there is no command)
by pressing the Return-Key you accept the term and reach the next program line.
Example:
1 U E1
2 U E2
3 = A1
.
.
.
840 PE (Programm end)
You can edit the program now.
Leave the Program-Editor by typing E(Ret).
IF YOU CHANGED THE PROGRAMM YOU WILL HAVE
TO TYPE IN "PRZE" TO KEEP THESE CHANGES.
DON`T DO SO IF YOU WANT TO KEEP THE OLD
PROGRAMM !!!
Now you can start the A020 by pressing S(Ret).
I hope I was able to help you.
Best regards
