3-11) RS232C LOOP BACK TEST (XEA147 only)
a.
Test Procedure
Before turn the power on, connect the loopback test jig:
UKOG-6646RCZZ to RS232C port. And turn the power on then
set to [Z/PGM] mode then push [1] [1] and [PO] key, the RS232C
loop back test is started.
When stat the test mode, the machine checks the reading of input
control signal, at first.
< The control signal check >
The read check is that DTR and RTS changed in accordance with
following pattern then check the logic of DSR, DCD and CTS. In
this time, if the checked logic is same as following list, the test
result is OK. If not, it is displayed ‘ERROR’.

Test Procedure
With the above key operation, the RAM check is started.
At first, the address touch on address lines in all RAM area is
checked.
At first, the address touch on address lines in all RAM area is
checked.
<For example the address touch test in all RAM area>
To check the following address
0x61000000、0x61000001、0x61000002、0x61000004
0x61000008、0x61000010、0x61000020、0x61000040

0x61008000、0x61010000、0x61020000
To write ‘55h’ to 0x61000000
To write ‘AAh’ to other than 0x61000000
To check the data in 0x61000000, if 55h is written, the result is
OK. If not, result is NG.
To check the data in the other than 0x61000000, if ‘AAh’ is
written, the results is OK, if not, result is NG
To write ‘55h’ to 0x61000001
To write ‘AAh’ to other than 0x61000001
To check the data in 0x61000001, if 55h is written, the result is
OK. If not, result is NG.
To check the data in the other than 0x61000001, if ‘AAh’ is
written, the results is OK, if not, result is NG
To write ‘55h’ to 0x61020000
To write ‘AAh’ to other than 0x61020000
To check the data in 0x61020000, if 55h is written, the result is
OK. If not, result is NG.
To check the data in the other than 0x61020000, if ‘AAh’ is
written, the results is OK, if not, result is NG
Secondly, the write & verify test is executed.
The different writing data are written in to each address.
<For example>
Address Written data
0x6100_0000~0x6101_FFFF 00h write & verify
0x6100_0000~0x6101_FFFF FFh write & verify
0x6100_0000~0x6101_FFFF 55h write & verify
0x6100_0000~0x6101_FFFF AAh write & verify
The test result is displayed and printed out then test is finished
when the [TL] key pushed.
