11-2 Error Messages

An error message will appear if incoming data has any of the errors listed in table. Since the error is shown in the display for
informational purposes, the data transfer continues and you are allowed to perform the next operation.

key.
Appears if an instruction that the CM-500/400/300 cannot interpret is sent. This error is
generated if an instruction from the "mode2" set is sent when the unit has been set to
recognize "mode1," or viceversa. Change the setting for the recognized instruction set, using
the control panel, and this error should no longer occur.
Appears if the number of parameters differs from the permissible number.
Appears if the value specified for a parameter is out of the permissible range.
Appears if an unusable character is specified.
Appears if an output instruction is sent from the computer during execution of a previous
output instruction. More precisely, there is a certain amount of delay between the moment an
output instruction is given and the instant actual output begins. This error message appears if
the new output request arrives during this delay time. (The delay time can be set using the
[ESC].M instruction.)
Appears if a device control instruction that the CM-500/400/300 cannot interpret is sent.
Appears if an invalid parameter has been specified for a device control instruction.
Appears if the value for a device control instruction parameter exceeds the permissible limit.
Appears if the number of parameters for a device control instruction is more than that
permissible.
Appears if a framing error, parity error, or overrun error occurs at the time of data
reception.(There is a problem with one of these settings: Baud Rate, Parity, Stop Bits, or Data
Bits. The protocol settings for the CM-500/400/300 must be made correctly in order to match
the settings your computer is set to use.)
Appears if the I/O buffer has overflowed.(There is a problem with the connecting cable, or
the settings for Handshaking. Make sure you are using a cable appropriate for the computer
being used. Also, check that the setting for Handshaking is correct.)
