Troubleshooting
If the connection was properly established, there should be a string
containing “
hh:mm:ss ... UpdateRack added receiver: 119.X.X.X... ” where
hh:mm:ss reflects the time the Ethernet cable was reconnected, and
119.X.X.X reflects the IP address of the receiver.
e. If a string such as that shown in step d above is not present, then the
connection has not been properly established. See Troubleshooting on page
5-1.
AC line voltage test
This test verifies that the domestic wall outlet supplying power to the equipment is
properly wired. For international wiring tests, refer to the internal standards agencies
of that particular country.
120 VAC, 50/60 Hz
Use a digital voltmeter to check the voltages of the 120-volt AC wall outlet (dedicated
circuit recommended). If the measurements are significantly out of range, have a
qualified electrician repair the outlet. The voltage measurements should be as
follows:
1. 120 VAC (± 10 VAC) between the line contact and neutral and between the line
contact and ground.
2. Less than 3 VAC between neutral and ground.

240 VAC, 50/60 Hz
Use a digital voltmeter, set to measure at least 300 VAC, to check the voltages of the
NEMA 6-20R, AC wall outlet (dedicated circuit recommended). If the measurements
are significantly out of range, have a qualified electrician repair the outlet. The
voltage measurements should be as follows:
1. 120 VAC (± 10 VAC) between either “hot” contact and ground.
2. 210 to 230 VAC between the two “hot” contacts.
