When checking with two or more satellite machines connected,
enter the terminal No. (000 ∼ 015) and press the ENTER key
for each satellite connected. To execute, press the ENTER key
without entering the terminal No. The display is as shown be-
low. Do not use the same terminal No. for different machines
(master/satellite).

Data Sequence Number
With the above setting, data transmission between the master
machine and the satellite machine is started.
Check content
•
Data in the following format composed of 2byte sequence No.
and 254byte AAH data are transmitted from the master ma-
chine to the satellite machine. The master machine displays the
sequence No.
Test data format (1 packet = 256byte)
1 2 3 4 5
XX XX AA AA AA
XXXX : Sequence No. (2byte: 4digits of binary decimal numbers)
AA : Transmission data (AAH) x 254 bytes
•
The satellite machine sends back the received data to the mas-
ter machine. The satellite machine displays the received se-
quence No.
•
The master machine receives the data, and checks the se-
quence No. and 256byte AAH data. In case of an error, the
master machine displays an error code and terminates the
check. If two or more satellite machines are used, the above
operation is repeated. If data transmission with all the satellite
machines are normally completed, the master machine incre-
ments the sequence No.
The above operation is repeated.
