LED Port (CN9)
CN9 has the five LED Ports. The ports use the respective isolated power. Each port is independently isolated
up to 2500V, and does not require any limiting resistors, allowing you to directly connect an LED to the port.
2 Connectors
Note
The LEDs are independently isolated from each other, and the LEDs will automatically be disabled if the respective
serial port is turned off. The LEDs cannot be configured.
