Checking
i. The master machine sends data of the following format con-
sisting of 2-byte sequence No. and 254-byte AAH data to the
satellite machine. The master machine displays the sequence
Nos.
Test data format (1 packet: 256 bytes)
1 2 3 4 5
XX XX AA AA AA
XXXX : Sequence No. 2 bytes (4-digit binary coded decimal
number)
AA : Transfer (AAH) ~ 254 bytes
ii. The satellite machine returns the data it has received, to the
master machine as it is. The satellite machine displays the
sequence No. on the screen.
iii. The master machine receives the data and then checks the
sequence Nos. and 254-byte AAH data. If an error occurs, the
master machine displays an error code and ends the test. If
there are multiple satellite machines, steps i and ii are re-
peated.
The master machine advances the sequence No. when data is
transferred successfully between it and the satellite machines.
Steps i - iii are repeated.
