Table 2: CEA-709 Activity LED Patterns
3.4.5 Ethernet Link LED
The Ethernet Link LED lights up green whenever an Ethernet cable is plugged-in and a
physical connection with a switch, hub, or PC can be established.
3.4.6 Ethernet Activity LED
The Ethernet Activity LED lights up green for 6 ms whenever a packet is transmitted or
received or when a collision is detected on the network cable.
3.4.7 CN/IP LED
The CNIP LED is a three color LED that indicates different operating states of the L-
Gate’s CEA-852 device.
Green: The CEA-852 device is fully functional and all CEA-852 configuration data
(channel routing info, channel membership list, send list) are up-to-date.
Green flicker: If a valid CEA-709 packet is received or transmitted over the IP channel, the
CNIP LED turns off for 50 ms. Only valid CEA-709 IP packets sent to the IP address of
the L-Gate can be seen. Stale packets or packets not addressed to the L-Gate are not seen.
Yellow: The CEA-852 device is functional but some configuration data is not up-to-date
(device cannot contact configuration server but has configuration data saved in Flash
memory)
Red: The CEA-852 device is non-functional because it was rejected from the CEA-852 IP
channel or shut-down itself due to an internal error condition.
Off: The CEA-852 device is non-functional because it has not been started. This can be the
case if the L-Gate uses DHCP and it has not received a valid IP configuration (address)
from the DHCP server.
Flashing Red at 1 Hz: The CEA-852 device is non-functional because it is started but has
not been configured. Please add the device to a CEA-852 IP channel (register in
configuration server).
Flashing green or orange at 1 Hz: The L-Gate’s CEA-709 side of the gateway has not been
commissioned yet. The color indicates the CEA-852 IP channel status as described above.
3.4.8 BACnet/IP LED
The BACnet/IP LED flashes green for 25 ms when BACnet packets are transmitted or
received over the BACnet/IP interface.
