Operation
6.1 Setting the RS-232C Communication Conditions
・
Use the communication condition setting switches on the RS-232C panel to set
the communication conditions.
・
On dispatch from the factory, this address is initially set to 00000000.
・
If you change the communication conditions while the 3157 is being used,
then you should immediately turn the power off and on again.
If this is not done, the communication conditions will not be changed to the
new ones.
・
When using with the personal computer, set bit 8 to 0.
・
When using with the optional 9442 PRINTER, set all bits to 1.
・
When the 3157 soft start mode is enabled, its operation slows down at starting
test. This may cause a communication error, depending on the preset baud
rate.
