Repeat Cycles
When a data register is assigned to repeat, as many consecutive data registers, as the repeat cycles, are used to transmit data in
the same conversion type and transmit digits.
Example:
Data from data registers starting with D10 is converted in BCD to ASCII and is transmitted according to the designated repeat
cycles.
BCC (Block Check Character)
Block check characters can be appended to the transmit data. The start position for the BCC calculation can be selected from the
first byte through the 15th byte. The BCC can be 1 or 2 digits.
