Serial port 9-pole D-SUB female connector for serial RS 232 communication; see RS-232 
Control Port for more details.

DVI input 29-pole DVI-I connector, however only digital pins are internally connected. Connect 
single link DVI source. The unit has minimal cable compensation ability, hence the 
maximum recommended cable length – in compliance with the DVI standard – is 
5 m. See DVI Inputs and Outputs section for more information.
4
Monitor output 29-pole DVI-I connector, however only digital pins are internally connected. A local 
display device can be connected to check the outgoing signal. The resolution and 
pixel clock frequency are the same on the DVI and Neutrik connectors, no internal 
scaling or conversion is applied to the signal. See DVI Inputs and Outputs section 
for more information.

Laser Active LED
on
It gives feedback about the operation of the optical module (laser is 
enabled), that means the laser radiates invisible waves. Avoid direct eye 
contact with the optical connectors!
off
Laser module is not active (laser is disabled on the output port).

Break-out 
connector
The break-out LC connector is internally connected to output B of the Neutrik 
Typical Stand-Alone Application with Break-Out Connection 
and Application Example of Break-out Connector section for more details.
