PWR
This LED (green) is illuminated while the CEN-TVAV power-in cord is plugged
into an energized VAC outlet. There is no ON/OFF switch for the CEN-TVAV.
NET
This LED (yellow) illuminates when communication with Cresnet peripherals is
occurring or while processing commands from the PC (i.e., uploading,
programming). The connections to these devices are made through the rear panel
CRESNET port.
ETHERNET
These four front panel LEDs are active while the CEN-TVAV is connected to a LAN
or WAN through the rear panel ETHERNET port. The RXD (green) LED
illuminates during reception of Ethernet data and TXD (green) illuminates during
transmission of Ethernet data. The LNK (yellow) LED illuminates when there are
attachments to the Ethernet network and ERR (red) illuminates when an Ethernet
protocol error is detected.
INPUT-OUTPUT
These four LEDs (red) labeled 1-4 illuminate while the corresponding input or
output device that is connected to the rear panel I/O is active.
TV/AV
The PWR (green) LED is illuminated while the current sensor is detecting that the
TV or AV device connected to the power-out receptacle is ON. The IR (red) LED
illuminates when IR signals are being sent out the IR port.
RS-232
The RXD (red) LED illuminates when the CEN-TVAV is receiving serial data from
the RS-232 port. The TXD (red) LED illuminates when the CEN-TVAV is sending
data to the port.
NOTE: The IR receiver, for use with an optional handheld IR transmitter, is located
behind the red lens between the RS-232 and IR IN indicators.
IR IN
This LED (red) illuminates when the CEN-TVAV receives a valid IR code from an
optional handheld transmitter.
