The same command as the sending command from external device to PV310 is
transmitted.
Response: Error 1
% U CR
Cause:
Command in the unspecified form or not provided was received.
Examples:
- %G100800100
C
R

(not provided command)
Response: Error 2
• ERROR signal = “ON”
• Error Code: E0177 is
displayed on the screen
% Z CR
Causes:
• Checker number specified by a sending command does not include the target
checker.
• The edge threshold specified by a sending command is not between 001 and
0255 or 1 and 0255.
• If the scan direction of Position Adjustment (Gray Edge) checker is set to either
“Vertical” or “Horizontal”, the other unset edge threshold is specified to any
other number than “0”.
*1

other edge threshold must be “0” (if the edge threshold is specified to any other number than "0", an error
response %Z
C
R
will be output). A response to the change command from external device is send as “0”.
Example: If “Horizontal edge threshold” is specified to “100” and Vertical edge threshold is not specified,
• Sending command
