6.5 How to Read Communications Error Information
The result of communications on the E5CK can be checked by the end code in the response frame. Use this
end code to remedy errors that may occur.
Communications are normal when the end code in the response is “00”.
If the end code is not “00”, this indicates that an error other that is not an
undefined error has occurred. The end code format is as follows and does
not contain a data area.

Code name
Parity error
Parity check error was detected in the received data.
Check the communications condition. If the communications condition of
the host computer and E5CK controller match, then a probable cause is
a problem in the communications circuit of one or both of the host com-
puter and E5CK controller.

Code name
Framing error
Stop bit cannot be detected.
Check the communications condition. If the communications condition of
the host computer and E5CK controller match, then a probable cause is
a problem in the communications circuit of one or both of the host com-
puter and E5CK controller.
