A low signal indicates normal laser operation and a high signal indicates a fault. The TX FAULT will be latched high when a laser fault occurs and is cleared by toggling the TX DISABLE input or power cycling the transceiver. The transmitter fault condition can also be monitored via the two-wire serial interface (address A2, byte 110, bit 2). 2
