2 Details of test
Keyboard check is performed with the sum check data of key
code.
For sum check data, data are inputted to the upper four digits
before the diagnostics code. The data are compared with the
added data which are added until the final key (TL) is pressed. If
the data agree with the added data, the end print is made. If not,
the error print is made.
The sum check data is obtained by totalizing all key hardware
codes except for the TL key and converting the total into a deci-
mal figure.
