CHAPTER 5. TEST FUNCTION 1. TEST ITEMS 2) KEY CODE 1 Key operation The test items are as follows: NO.
4 End of testing 3 Check that: When the test ends normally When an error occurs 104 E- ~ - 104 “-” blinks and the clock counts up. 4 End of testing Note: Calculation of key sumcheck data The hard code (hexadecimal number) at the position (excluding feed key) where there is an input data contact is added. However, the end key (CA/AT/NS) is not added.
4 End of testing 12) AD conversion port The program ends after printing. 1 Key operation When the test ends normally. When the test ends abnormally. Ex- ~ - 120 120 ***** x = 1: Data error x = 2: Address error 160 2 Test procedure The test program displays the voltage of each AD port. 1. Head temperature When an error occurs, the printer outputs the error message and then the address where the error has occurred in the area ****. 2. Head voltage 3.
CHAPTER 6. IPL (Initial Program Loading) FUNCTION The application program of the XE-A202 is written into the Flash ROM in the CPU. 7) Copy the following files in "PosUtilityTool3" into the hard disk of PC. Since the CPU supplied as a service part does not include the application program in it, the application program must be written when the CPU is replaced with a new one.
APPENDIX: RS232C CABLE The RS-232C cable (QCNWG3190BHZZ) provided together with the XE-A202 is used to connect the XE-A202 and a PC when using the customer support tool or performing IPL. When using the cable, connect the core side of the cable to the XEA202 as shown in the figure below. PC CHAPTER 7. CAUTION TO BE USED WHEN CONNECTING THE RS-232 CABLE When connecting the RS-232 cable to the XE-A202, be sure to observe the following condiiton: XE-A202 Use RS-232 cable (with core) of accessories.
