676T / 676R Quick Start Guide
This guide helps you install and use your 676T / 676R for thefirst time.
Go to www.kramerav.com/downloads/676T or www.kramerav.com/downloads/676R todownload the latest
user manual and check if firmware upgrades are available.
Step 1: Check what’s in the box
676T HDMI Optical Transmitter or
676R HDMI Optical Receiver
1 Bracket set
4 Rubber feet
1 Power cord and adapter
1 Quick start guide
1 OSP-MM1 Fiber Optic SFP+ Transceiver
Step 2: Get to know your 676T and 676R
676T can be connected to a single 676R device or to multiple devices via optical splitters. When multiple devices are connected, a
receiver device is defined as primary when its Tx (SFP+ OUT) optical fiber is connected directly to the 676T Rx optical fiber (SFP+ IN).

Step 3: Mount 676T/676R
Install 676T/676R using one of the following methods:
•Attach the rubber feet and place the unit on a flat surface.
•Fasten a bracket (included) on each side of the unit and attach it to a flat surface
(see www.kramerav.com/downloads/676T).
•Mount the unit in a rack using the recommended rack adapter
(see www.kramerav.com/product/676T).
•Ensure that the environment (e.g., maximum ambient temperature &
air flow) is compatible for the device.
•Avoid uneven mechanical loading.
•Appropriate consideration of equipment nameplate ratings should be
used for avoiding overloading of the circuits.
•Reliable earthing of rack-mounted equipment should be maintained.
•Maximum mounting height for the device is 2 meters.

Step 4: Connect inputs and outputs
Always switch OFF the power on each device before connecting it to your 676T/676R.
For optimal performance, use the recommended Kramer cables available at www.kramerav.com/product/676T.
Using third-party cables may cause damage!
To install/replace the OSP-MM1 or other Kramer recommended SFP+
transceiver:
1. Pull the bail out and remove the currently installed transceiver,
insert the protective cap and store in a safe place.
2. Make sure the bail of the new transceiver is pushed up, in the
closed position.
3. Insert the new transceiver into the relevant optical device SFP+ slot
and push it in until it clicks.
4. Remove the protective cap and store it in a safe place for future
use.
Warning: Connecting the OSP SFP+ connector to an LC(APC) fiber
connector may cause poor performance and damage the connector!
Refer to www.kramerav.com/downloads/OSP-MM1 for more information.
Warning: Class 1 Laser Product
•Invisible laser radiation present.
•Avoid long-term viewing of laser.
•Avoid the use of magnifying viewing aids or instruments (such as binoculars, telescopes, microscopes and
magnifying lenses, but not spectacles or contact lenses).
•Avoid placing optical devices in the emitted beam that could cause the concentration of the laser radiation to be
increased.
Step 5: Connect power
Connect the power cord to 676T/676R and plug it into the mains electricity.
Safety Instructions (See www.kramerav.com for updated safety information)
Caution:
•There are no operator serviceable parts inside the unit.
Warning:
•Use only the power cord that is supplied with the unit.
•Disconnect the power and unplug the unit from the wall before installing.

Step 6: Operate 676T and 676R
Set the 676T DIP-switches
The DIP-switch setup on 676T applies to all the 676R devices that are connected.
A DIP-switch that is down is on, up is off. Changes to the DIP-switches take effect immediately. By-default, all DIP-switches
are set to Off
