3.2 Setting the Transmission Speed and Transmission Format
Explanation of the bits
If the power supply is turned on with the factory settings still in effect, the status of the
bits in the transmission format address section (COM.1 1003 and COM.2 1004) in the
shared memory is as follows: 0000 0001 0001 1010 = H011A.

To set the control signals CS and CD valid from the factory setting state, first turn bit 7
on, and then set the bit status to 0000 0001 1001 1010. This writes “H 019A” in the
program above to the shared memory.
