the ECMS user station.

• Check the video quality using a different monitor.

No response from USB mass media device attached to the ECMS user

station

ECMS user station. If the mass media device is connected to the ECMS user station via a USB

hub, it will not be possible to access it.

• Ensure that both of the USB connectors from the transmitter are securely connected to the cor-

rect ports on the remote workstation.

• Verify that the mass media device is functioning correctly by attaching it to the USB port on

another computer. If the mass media device is not functioning correctly, replace it.

Slow file transfer rate from or to the USB mass media device

• Check if at least one of the transmitter USB cables is connected to a high speed USB port on

the remote computer. The transmitter will operate with Low Speed and Full Speed USB, but

the file transfer rate will be slower.

Connection to remote workstation is lost

• Verify that the network cable is securely connected to the RJ-45 connector at the rear of the

ECMS user station.

• Verify that the ECMS user station is linked to the network and that it is receiving data.

• Ensure that both of the USB connectors from the transmitter are securely connected to the cor-

rect connectors on the remote workstation.

• Verify that the transmitter is drawing sufficient power from the USB connections on the remote

computer and that it has booted correctly:

• If the green LED on the transmitter is on, the transmitter is drawing sufficient power.

• If the transmitter cannot draw sufficient power from the remote workstation, obtain an

external power supply unit for the transmitter from Avocent.

• The transmitter has an internal fan. Verify that the fan is functioning.

• Ping the transmitter from another PC on the network to ensure it is connected.

• Reset the transmitter.

• Reset the ECMS user station.

• Verify that the Ethernet network is fully operational.
