ond byte data to the external controller. If the device can not recognize the matching data, it does
not transmit the echo back data and waits for the matching data again with automatic baud rate adjust-
ment. Therefore, the external controller should transmit the matching data repeatedly till the device
transmits an echo back data. The transmission repetition count varies depending on the frequency
of device. For details, refer to Table 15-5.
rate modification data shown in Table 15-4 are available. Even if baud rate is not modified, the exter-
nal controller should transmit the initial baud rate data (28H: 9600 bps).
ing to the device's operating frequency, the device echoes back data the value which is the same da-
ta in the 4th byte position of the received data. After the echo back data is transmitted, baud rate mod-
ification becomes effective. If the 3rd byte of the received data does not contain the baud rate mod-
ification data, the device enters the halts condition after sending 3 bytes of baud rate modification er-
ror code (62H).
the device echoes back the value which is the same data in the 6th byte position of the received da-
ta (in this case, 30H). If the 5th byte of the received data does not contain the operation command da-
ta, the device enters the halt condition after sending 3 bytes of the operation command error code
(63H).
ta received with the 7th byte has no receiving error, the device does not send any data. If a receiv-
ing error or password error occurs, the device does not send any data and enters the halt condition.
received with the 9th byte has no receiving error, the device does not send any data. If a receiving er-
ror or password error occurs, the device does not send any data and enters the halt condition.
the data received with the 11th byte has no receiving error, the device does not send any data. If a re-
ceiving error or password error occurs, the device does not send any data and enters the halt condition.
ta received with the 13th byte has no receiving error, the device does not send any data. If a receiv-
ing error or password error occurs, the device does not send any data and enters the halt condition.
