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.
