3.4.9 CNIP LED
This LED is available on L-INX models 10X, 11X only. The CNIP LED is a three color
LED that indicates different operating states of the device‘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
LINX-10X can be seen. Stale packets or packets not addressed to the device are not seen.
Yellow: 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)
