See TD+ 20 VEET Transmitter Ground (Common with Receiver Ground) 1 Notes: 1. Circuit ground is internally isolated from chassis ground. 2. Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V. 3. Should be pulled up with 4.7k – 10kohms on host board to a voltage between 2.0V and 5.5V. MOD_DEF(0) pulls line low to indicate module is plugged in. 4. Receiver achieves multi-rate operation without active control. 5. LOS is open collector output. Should be pulled up with 4.7k – 10kohms on host board to a voltage between 2.0V and 5.5V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
