Gefen EXT-HDMI1.3-1FO Manuale Utente

• 

IR data repeater functionality is single-directional. IR data can only be 
transmitted from the Receiving unit back to the Sending unit. IR data cannot 
be transmitted from the Sending unit to the Receiving unit. 

• 

Use one SC-terminated multi-mode fi ber optic cable to operate the HDMI 1.3 
Over One Fiber with IR.

• 

1080p video may be extended up to 1000 feet (300m), depending on the 
type of fi ber optic cable used. The following maximum extension distances 
will be possible depending on the types of fi ber optic cabling that are used:

• 

100m (330 ft) on 62.5/125 μm (OM1) multi-mode SC fi ber

• 

300m (1000 ft) on 50/125 μm (OM3) multi-mode SC fi ber

• 

RS-232 data is bi-directional for direct commands and echo function or 
status information.

These steps must be followed when setting up the Gefen Extender for HDMI 1.3 
over one Fiber with IR

 for the fi rst time.

• 

Connect the SC fi ber optic cable between the Sender unit and the Receiver 
unit.

• 

Set DIP switch 3 on both the Sender unit and the Receiver unit to the OFF 
position.

• 

Apply power to the source and to both the Sender and Receiver units.  The 
LED indicators on both the Sender unit and Receiver unit will alternate from 
red to green during the calibration process.  The calibration process can take 
up to 120 seconds to complete.

• 

After the calibration process has fi nished, the LED indicators on both the 
Sender unit and the Receiver unit will be solid green.  Set DIP switch 3 to 
the ON position on both the Sender unit and the Receiver unit to lock the 
calibration settings.

When changing fi ber optic cables, the calibration procedure must be 

repeated.  See page 11 for details on the calibration procedure.
