SELECT TX CLOCKING MODE:
INT EXT LOOP-TIMED (ENT)
INTERNAL - indicates that the CiM-550 will supply a clock to the DTE, which
is derived from its internal high-stability source.
EXTERNAL - indicates that the CiM-550 expects to receive a clock from the
DTE, to which the unit can phase-lock its internal circuits.
LOOP-TIMED - indicates that the transmit timing source should be the receive
clock, from the direction of the satellite. This is a useful mode, in that no external
connection needs to be made in this mode. If the demodulator loses lock, or if
there is no receive signal present, the internal clock is substituted. Note also that
this mode will work even with asymmetric RX and TX data rates.
