CHAPTER 6. IPL (INITIAL PROGRAM LOADING) FUNCTION
The application program of the XE-A202 is written into the Flash ROM
in the CPU.
in the CPU.
Since the CPU supplied as a service part does not include the applica-
tion program in it, the application program must be written when the
CPU is replaced with a new one.
To write the application program into the Flash ROM, connect the PC
and the XE-A202 with an RS-232C cable, and execute the PC software.
and the XE-A202 with an RS-232C cable, and execute the PC software.
*
Use a D-Sub 9pin cross cable employed in conventional communica-
tion between ECR-ECR (See APPENDIX: RS232C CABLE).
[Related parts/Tool]
[IPL PROCEDURE]
1) Connect the XE-A202 and PC with an RS-232C cable.
<XE-A202 side>
2) Turn off the AC Power. (& remove batteries.)
3) Open the cabinet.
4) Change the IPL JUMPER PIN (SP1) to the rear side.
5) Close the cabinet.
6) Turn on the AC Power.
(At this time, ECR looks like inactive, but ECR waits the ROM data
from PC.)
<IPL software on PC>
7) Copy the following files in "PosUtilityTool3" into the hard disk of PC.
Postool3.exe
A202v.ROM
8) Boot "Postool3.exe."
9) Push [Add Files] in the screen.
10) Select the ROM DATA file. (File name: A202V.ROM)
11) By pushing [Send] in the screen, the ROM data is sent from PC to
ECR.
The address counter is shown on PC and counts up.
12) After about 3-minuites, the message "Complete" is shown on PC.
