Term	Definition
Tile Network Location (TNL)	A unique number generated to identify each tile in the system. The first character represents the adapter, the next represents the strand and the third character represents the tile number. For example, tile A8 is on the first adapter, where there is only one strand and it's the 8th tile on that strand. Tile Bb30 is on the second adapter, is on the 2nd strand on that adapter and is the 30th tile in that strand.
Errors	Depending on the severity, errors appear as either a warning, a critical warning or a visual fault. If you need assistance with troubleshooting specific errors, please view our Console Documentation.
Warning	A type of error that indicates when particular operations are outside of the preset thresholds. Warnings may not typically require immediate action but collectively, they may indicate a bigger issue.
Critical Warning	An error type that indicates when operations heavily exceed the thresholds. Although they may not require immediate action, Critical Warnings will need attention very soon to prevent a more severe fault.
Visual Fault	A type of error that is likely to affect what is seen on the screen and will generally need immediate attention.
Daemon	The daemon ensures that the controller is not crashed and that it's running. There are a few variables that it monitors and if any of them stop sending, it will restart. This prevents the software issue from impacting a customer.

Term	Definition
Model	The model number of the tile.
Serial	The unique serial number assigned during manufacturing.
Firmware	The software programmed into the controller on each tile.
Factory Version	Version of factory firmware currently running on the tile.
Incomplete Frames	The number of times a frame has been dropped.
Short Frames	Frames that are displayed for shorter than usual. There is usually an amount of long frames that correspond with the short frames.
Long Frames	Frames that are displayed for longer than usual. There is usually an amount of short frames that correspond with the long frames.
VSYNC Drops	This indicates the number of times a frame is not displayed. This number should always be either zero or uniform across all tiles.
VSYNC Packets	Vsync denotes how often the frame refreshes. This statistic shows how many vsync packets have been sent.
Min VSYNC	The minimum frequency of frame refreshes.
Avg VSYNC	The average frequency of frame refreshes.
Max VSYNC	The maximum frequency of frame refreshes.
Video Packets	How video data is sent - instead of transferring a large file as a single block of data, the video is sent in smaller packets. If a packet is not received or is "dropped," only the dropped packet needs to be resent. Additionally, if a data transfer encounters network congestion, the remaining packets can be rerouted through a less congested path.
LED Firmware	The software programmed into the LED board on each tile.
OC LED Test	The number of open circuit (dead) LEDs found.
LED Chain Errors	Number of chain errors detected.
LED Temp	The temperature of the LED board. The value is reported in degrees Celsius after it has been multiplied by 10 (i.e. 90 degrees is shown as 900).
Local Temp	The temperature of the local board. The value is reported in degrees Celsius after it has been multiplied by 10 (i.e. 90 degrees is shown as 900).
Local Vref	The local voltage reference. Voltage reference is an electronic device that ideally produces a fixed (constant) voltage irrespective of other factors.
Link	Number of ports with link.
Stats Received	Number of stats packets sent from the controller and received by the tile.
Status Received	Number of status packets sent from the tile and received by the controller.
Last Comms	Time since last packet received.
Uptime	The length of time that a tile has been running continuously since the last reset.
Total Uptime	The total length of time that a tile has been running continuously.
Runtime	Amount of time in seconds a tile has been running since last power cycle.
Total Runtime	Amount of time in seconds a tile has been running. Does not reset.
Inventory	Internal asset identifier.
LED Vdda	Used for development only.
Min Phase	Used for development only.
Avg Phase	Used for development only.
Stack Headroom	Used for development only.
Gclock unlock	Used for development only.
Debug	Used for development only.
