COMMUNICATION WITH PC

11-1 Communication Parameter Specifications

The communication parameters on the PC should be set as follows. For the setting procedure, refer to the computer operation manual.

■ Baud rate	9600 bps
■ Data bit length	8 bits
■ Stop bit length	1 bit
■ Parity check	On
■ Parity setting	Odd
■ Control method	XON/XOFF software control
(X parameter)	(Effective)
■ Communication method	Full duplex
■ Sync method	Asynchronous method
■ Return key transmission	CR code
■ CR code reception	For CR/LF reception : Return + line feed
	For CR reception : Return

*If the above parameter settings are not possible due to your equipment specifications, the robot controller settings can be changed by changing PRM47 (communication parameter settings) from the TPB.

PRM47 settings (default value: 0)

bit	Function			Selection
15 to 9	Reserved	Always set to 0.
8	Termination code	0: CR + LF		1: CR
7 to 4	Transmission speed	0: 9600bps	1: 300bps	2: 600bps	3: 1200bps
		4: 2400bps	5: 4800bps	6: 9600bps	7 to 15: Cannot be set
3	Data bit length	0: 8 bits		1: 7 bits
2	Stop bit length	0: 1 bit		1: 2 bits
1 to 0	Parity check	0: Odd	1: Even	2 to 3: Non

Example: To set the data bit length to "7 bits" and the parity check to "Non", enter "10" for PRM47, which is given by

0000000000001010 (binary) = 10 (decimal)

c CAUTION

Be sure to use a cable which conforms to specifications listed in "11-2 Communication Cable Specifications". The settings will be invalid if other cables such as POPCOM communication cables or those having different specifications are used.

After changing the parameters, turn the power off and then turn it on again to enable the settings. The TPB can be used even if the parameters have been changed.
