• Every room where you plan to install a set-top
• The signal levels you measured at the RF cable outlets
• HFC MAC Address located on the label on the bottom of the set-top used in that
room
2. Optionally, you can include information such as the set-top type, serial numbers, and
anything else you or the service provider considers useful. The following table provides
an example of signal levels and MAC addresses.
Room
Cable Outlet
Signal Level
Set-top MAC
Address
Set-top Type Serial Number
Router -2 dBmV 001225xxxxxx None
Living Room -6 dBmV 001225xxxxxx IPC4100
Den -8 dBmV 001225xxxxxx IPC4100
Master
bedroom
1. -16 dBmV
001225xxxxxx IPC4100
2. Use your TV signal tester at the coaxial outlet where you will connect any MoCA set-top
box and router. Verify that the signal level of the highest downstream digital channel
frequency is between -10 and 10 dBmV. Record your readings in a table similar to Table
6 above. A signal level of +0 dBmV is ideal.
Note: If the signal level is less than -10 dBmV, you must correct the problem before
installing the set-top box.
3. If possible, determine whether there are one or more in-line coaxial RF amplifiers. If
possible, move the existing amplifier to a position near the point of entry. See
Troubleshooting for more information.
4. If possible, determine how many splitters, and what kind, are in use. An older splitter,
such as an old eight-way splitter, may have unacceptably high throughput loss. Replace
any splitter cascades having a loss of 18 dB or more.
5. If the signal level at one or more coaxial outputs remains unacceptably low, the power
loss may be caused by long coaxial cable runs using cable of insufficient quality. For
example, a 330 ft (100 m) cable can reduce the power by 20 to 27 dB, depending on the
cable quality. This results in a very low power level at the outlet of about -5 to -10 dBmV
or lower. This loss, combined with loss from a splitter, causes marginal MoCA network
performance.
6. If you make any changes to the network, repeat steps 1 and 2.
