Network clocking
The network clock setting specifies the number of physical external clock signals.
Use ‘RS449/V35 Compatible’ when the external equipment provides two clock signals, one for transmit and one
for receive. The difference between RS449 and V35 is the cable only.
Use ‘X21 Compatible’ when the external equipment provides a common clock signal for both transmit and
receive.
