Sync Data Polarity.
When using the synchronous data interface (e.g. V.35), the polarity of the clock signals
may become critical to the successful interfacing of EX7100 to external devices. Many
V.35 devices, especially those manufactured in North America, may have their clock
and/or data signals inverted. For this reason, EX7100 allows the user to select either
normal or inverted clock signals.
