11-1 Communication Parameter Specifications
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.

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.
