♦Setting the communicating mode

The settings can be made on RS-232C SETTING of the <REAR TERMINAL> menu. Set the Unit and the modem or a personal computer with same settings. Please refer to the diagram for possible setting rate.

Synchronization	Name on Menu	Asynchronous
1 Transmission rate at	TRANSMISSION	1200/2400/4800/
the data received/	RATE	9600
sent
2 Data bit length	DATA BIT LENGTH	8 BIT/7 BIT
3 Parity bit setting	PARITY BIT	NONE/ODD/EVEN
4 Stop bit length	STOP BIT	1 BIT/2 BIT
5 Line feed setting	DELIMITER	CR/CR•LF

#Set other functions on the personal computer as shown below.

Synchronization	Name on Menu
1X control	Not available
2S parameter	Not available
3CS-RS hamd-shake	Available

Please note that the RS-232C interface (located on the back of the unit) does not function while the unit is in commu- nication mode.

■Command code and status

Operation and setting of this unit by a personal computer is executed by command codes and error codes.

1) Command : an order from a personal computer to the unit

Command code	Parameter 1	,		Parameter 2		,	• • • • • • • • • •
	• • • • • • • • • •		,		Parameter n		Delimeter
							(sending) #1

2) Command : a reply from the unit ( indicated on a personal computer)

Status	Parameter 1	,		Parameter 2		,	• • • • • • • • • •
	• • • • • • • • • •				Parameter n		Delimeter
			,				(receiving) #2

#1: If you set the DELIMITER setting to "CR" on the RS-232C setting menu, input a Carrige return code (0DH).

If you set the DELIMITER setting to "CR • LF" on the RS-232C setting menu, input a carrige return code (0DH) and a line ****code (0AH).

#2: If you set the DELIMITER setting to "CR" on the RS-232C setting menu, output a Carrige return code (0DH).

If you set the DELIMITER setting to "CR • LF" on the RS-232C setting menu, output a carrige return code (0DH) and a line ****code (0AH).

Make sure to send commands in an interval of 0.1 second.

♦ Example of Command operation

Example 1) Turn the Unit on.( when DELIMITER is set to "CR" on the RS-232C setting menu)

Command from	Replied status code from uint	Meaning
personal computer	to a personal computer
PW1 CR		Sending a command to turn the Unit on.
	RC CR	The unit received a command.
	EX CR	The unit received a command and executed.
