- Connectivity with the controller -
•
When a communication error occurs between the
C231 and controller (the EZ-1 or CB-1), the
controller sends an error signal to the main body.
The C231 sometimes does not send a response
signal to the controller and the controller stays in
the busy condition. The LED on the controller
stays blinking until it is switched off.
•
This problem does not occur when the controller
is properly communicating with the main body.
However, once any communication errors occur,
there is possibility that this problem could occur.
With the new firmware The C231 can send the
response signal properly even if a communication
error occurs.
- Error in the User Code mode -
•
Even when the User Code mode was enabled by
SP120, the machine could not be reset (to enter
the user code entry display) by pressing the keys
as explained in the manual.
•
The only way to reset it was to wait for the
automatic reset (the Auto-reset mode) or switch
the machine off and on.
This problem has been solved in this version.
