TRANSMITTER SECTION

Transmit Disable (TX1_Disable and TX2_Disable)

The transmitters accept a TTL and CMOS compatible transmit disable control signal input that shuts down the transmitter

optical output. A high signal disables the transmitter while a low signal allows normal dual-transmitter operation. Also laser

is disabled when TX Disable is open. In the event of a fault (e.g. eye safety circuit activated), cycling this control signal

resets the module. Host systems should allow a 10ms interval between successive assertions of this control signal.

Transmit Fault (TX1_FAULT and TX2_FAULT)

A catastrophic laser fault will activate the transmitter signal, TX*_FAULT, and disable the laser. This signal is an open

collector output (pull-up required on the host board). 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 cycling the power of the dual-transmitter. The transmitter fault condition can also be monitored via

the optional 2-wire serial interface (address A2, byte 110, bit 2).
