Roland PNC-900 user manual Instruction Format Parameter Range is default Explanation

Instruction	Format	Parameter	Range ([ ] is default)			Explanation
ESC .E	[ESC].E	None		Outputs an error code related to RS-232C interface
Output RS-232C				(see the table below), and clears the error
Error Code				simultaneously. At the same time, the error being
				displayed is canceled.
					Error	Possible cause
					code	and action
					0	No I/O errors
					10	Cause: after execution of an output
						command, other output instructions are
						sent before the output was not completed.
						Action: let the computer to read the PNC-
						900 output by the output instruction
						and then send another output instruction.
					11	Cause: an error occurs in a device
						control instruction.
						Action: correct your program.
					12	Cause: incorrect parameter are set to a
						device control instruction (the default
						value is set to the erroneous parameter)
						Action: correct your program.
					13	Cause: parameters are overflowing.
						Action: correct your program.
					14	Cause: the number of the parameters set
						is more than specified or a colon ':' was
						not used to terminate.
						Action: correct your program.
					15	Cause: framing error, parity error or over-
						run error at the time of data receipt .
						Action: match the communication
						protocols of both computer and PNC-
						900 (baud rate, data bit length, stop bit
						length).
					16	Cause: the I/O buffer overflows.
						Action: This error does not occur when
						hardware handshake is performed, but
						may occur when software handshake is
						performed. If this error occurs, check the
						remaining buffer capacity of the PNC-
						900 and send less data than the
						remaining buffer capacity.
ESC .L	[ESC].L	None		PNC-900 outputs the size of the I/O buffer to the
Output I/O buffer				computer when receiving this instruction. It usually
size				outputs 1024 (bytes).
Abort Instructions
ESC .J	[ESC].J	None		Aborts both the currently executed device control
Abort Device Control				instruction and output.
Instruction
ESC .K	[ESC].K	None		Continues to execute the CAMM-GL III instruction
Abort CAMM-GLIII				in operation, aborts other incoming CAMM-GL III
Instruction				instructions and clears the data buffer.
ESC .R	[ESC].R	None		Initializes all settings established by the device
Initialize Device				control instructions. Execution of [ESC].R brings
Control Instruction				the same states as the following device control
				instructions are executed.
					[ESC].J, [ESC].M:, [ESC].N:, [ESC].H:,
					[ESC].I: and [ESC].@:
