Each connector can be used as input or output.
Loop backup: The receiving card and controller form a loop via the primary and backup line connections

Interfaces

HUB75E connectors: 12 standard HUB75E connectors

connect to the module
Power connector: Connect to the input power.

Either of the connectors can be chosen.
5-pin LCD connector: Connect to the LCD

Control

Self-test button: Set the test pattern

after the Ethernet cable is disconnected, press the button twice to display the test pattern
Mapping 1.1: The cabinet displays the Ethernet port, receiving card, and controller numbers in different colors
Monitoring: Temperature and voltage monitoring without external devices

bit error detection

detection of Ethernet cable disconnections
Readback and backup: Firmware program readback

configuration parameter readback

dual backup of configuration parameters

dual program backup
