FarSync PCI T-Series Line Status LEDs
Line Status LEDs
There are 2 LEDs on the FarSync T-Series adapter, next to the 37-pin connector for the cable. These LEDs are used to reflect the line status.
When both LEDs are off, the driver has not been started (or has been stopped).
Other states of each LED reflect the status of a particular port; the LED nearest to the cable reports the state of Port A, the other reports the state of Port B.
If the LED is on without flashing, then the driver has been started, but no clock has been detected on the line (or the line has not actually been started). If the LED flashes, then the line has been started and a clock has been detected (whether internal or external).
