* Use this setting for synchronous or other
asynchronous protocols.
The transmitter will be active from the
startbit to 10 bit-times after the last high
databit.
Please note that only one master can be
used per system.
*) For other speeds please contact Westermo
**) Number of units is depending on the data rate and the total
system. "Number of units" means a typical value that can be
changed depending on the structure of the total system.
S1:3, 6 and 7 is not used.
