RF Signal Not Being Detected (Powering LNB from the Modem)
Step 2:
• Our next step is to test voltage on the hardware to determine if our power source is making it
all the way up to the LNB.
• Starting with the Modems “RX IN” port disconnected the coax cable and using a volt meter to
determine if the modem is outputting voltage. Please check with your ISP or satellite modem
provider to determine what the normal output should be.
• If no voltage is displayed, please exchange the modem.
• If proper voltage is displayed, reconnect the cable and proceed to Step 3.
Step 3:
• Disconnect the coax cable from the splitters “OUT” port coming from the “Power Pass”.
• Measure voltage on this end of the cable. If the voltage does not match the output from the
modem then replace the cable.
• If the voltage does match, reconnect the cable and proceed to Step 4.
Step 4:
• Disconnect the coax going into the “IN” port of the splitter as shown below.
• Measure voltage on the port. If the voltage does not match the output from the modem then
replace the splitter.
• If the voltage matches, please reconnect the cable and proceed to step 5.
