E : Error status
(01 : Framing error)
(02 : Over run error)
(04 : Parity error)
(40: Transmit/ Receive data error/ Data is not 55.)
(80 : Time out error)
Test procedure
1) Operate the send machine first. The send machine will wait the "C" signal (send request) reception
from the reception machine.
The send machine will wait the send request signal about 30 seconds. When it is over 30 seconds,
the time out error will be printed on the receipt.
2) Operate the reception machine. Then, the both machines are communicated each others. This time
first block data wait time is 5 seconds. The total resend request time is 5 time.
3) During communication waiting time, the display will show the "-" brinking on the most left side digit of
segment display. When the data is OK, the reception/transmission packet number will be displayed
on the segment display.
NOTE1: To stop this opeartion, press any or trun off the mode key switch.
NOTE2: The send packet data format is as follows:
( Communication format is 8 bits, even parity, stop bit= 1bit fixed.)
