The PAC to STIF LED test causes the PAC module to turn on the fiber optic driver LED that is normally used to send serial messages from the PAC module to the STIF board in the CAM Lite chassis. The test allows you to visually inspect the PAC serial transmitter and the fiber optic cables that connect to it.
1. Start the test by clicking on the Turn on the PAC to STIF Fiber optic LED button.
2. Disconnect the output fiber cable on the PAC to inspect the LED. If it is ON, then the transmitter is working.
