Audio/RS-232 TP input (wire pair 3 and 6) configuration
NOTE: The RS-232 output insert ports, when enabled (

value in the response reports whether
the adjustment value was within or
outside of the threshold.
NOTES: • 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 MTP signal generator (included with most models,
optional for the MTPX Plus 128).
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 RJ-45 connector on the signal generator is to the
right as shown at right). If the cable is shorter than 300 feet (90 m), place the switch
down.
• The MTP signal generator does not work on cable lengths over 400 feet (120 m). Set the level/
peaking to its maximum value of 255.
