5) The preset data are not changed even after updating unless the program of the CPU
board is substantially changed. If CU-200 is installed, we recommend you to save
the preset data in the CU-200 card as a precaution. See p. 6-45 for details.
6) There is no need to set the data transfer speed of the serial port of the PC.
The communication speed is 9600bps while an updating program is booted and
38.4kbps after updating is started.
The protocols are as follows:
* Format) - Data bit: 8 - Stop bit: 1 - Parity bit: None
* Flow control) - None
7) When the serial port number of the PC is other than “COM-1,” change and overwrite
batch file to the same as a port number of the PC, or changing COM port of the PC
to “COM-1”.
For example, when updating is performed by means of “USB – RS-232C interface,”
may be serial port number (USB) of the PC is other than “1”.
Procedure for rewriting COM port of batch file
1. Open [Control Panel] – [System] – [Device Manager] and check the COM port
number of the installed “USB – RS-232C driver” (e.i. COM 4).
2. Select the batch file to update and open the batch file on [File] – “Edit.”
3. For example, when a batch file “uparpa.bat” of ARPA CPU open, a text “uppg
/lf ldarpa.bin /hf arparom.hex /port 1 /sp 9600 /t 9999” is displayed.
4. Change “port 1” to the port number “port 4”, “uppg /lf ldarpa.bin /hf
arparom.hex /port 4 /sp 9600 /t 9999” as follow.
5. Select [File] – “Save” and save the edited text.
Note:
If the edited text cannot be saved, right-click the icon of the batch file, select
[Property] – “General” tag and check that the “Attribute” is not
check-marked in “Read only” box.
