Tie input

to output 1 and auto adjust
the peaking on input
X!
. The
X&
value
in the response reports whether the
adjustment value was within or outside of
the threshold.

Before issuing the auto calibration command:
1. Disconnect the power and RJ-45 cables at the MTP transmitter connected to
X!
.
2. Connect the two cables to the included MTP signal generator.
3. If the input cable is longer than 300 feet (90 m), place the Pre-Peak switch on the
MTP signal generator to on (up when the signal generator‘s RJ-45 connector is to the
right as shown at right).
N
The MTP signal generator does not work on cable lengths over 400 feet (120 m). Set the
level and peaking to its maximum value of 255.
Pre-Peak
is on.
