Frequently Asked Questions - 675R Kramer

What types of video inputs does the Kramer 675R support?

The Kramer 675R supports HDMI, VGA, and composite (RCA) video inputs, allowing connection of various sources such as computers, DVD players, and cameras.

Can the 675R convert analog video to digital?

Yes, the Kramer 675R can convert analog signals (VGA, composite) to digital HDMI, and also digital to analog for integration with older displays.

What maximum resolution does the 675R support?

It supports resolutions up to 1920x1200, including 1080p, making it suitable for HD content and computer displays.

Does the 675R require external power?

Yes, it requires a 5V DC power supply (1A), typically included with the unit. It can also be powered via USB if the current is sufficient.

How do I set up the Kramer 675R?

Connect your source to the input (e.g., HDMI), then connect the output to your display. Plug in the power adapter. The unit should automatically detect and convert the signal. Use the front buttons for manual adjustments if needed.

What is EDID emulation and why is it important?

EDID emulation allows the converter to present a fixed set of supported resolutions to the source, preventing handshake issues and ensuring consistent output. The Kramer 675R includes this feature for reliable operation.

Can I use the 675R with audio?

Yes, it supports embedded audio from HDMI sources as well as separate stereo analog audio input and output via RCA connectors.

Is the Kramer 675R compatible with all displays?

It is compatible with most modern displays that have HDMI, VGA, or composite inputs. However, some older displays may not support the output format; check your display's capabilities.

How do I clean and maintain the 675R?

Use a soft, dry cloth to wipe the exterior. Avoid using any liquids or cleaning agents. Ensure the unit is unplugged during cleaning.

What should I do if the 675R does not output any signal?

First, check all cable connections. Ensure the power is on. Verify that the source is set to a compatible resolution. If the issue persists, try a different input or output cable. Contact Kramer support if the problem continues.

Step 3: Install 675T/675R

Install 675T/675R 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/675T).

- Mount the unit in a rack using the recommended rack adapter (see www.kramerav.com/downloads/675T).

• 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.

Step 4: Connect the inputs and outputs

Always switch OFF the power on each device before connecting it to your 675T/675R. For best results, we recommend that you always use Kramer high-performance cables to connect AV equipment to 675T/675R.

When using a duplex OSP SFP+ transceiver, connected with 2 fiber strands, always cross-connect the fiber connections, Rx OUT to Tx IN and Rx IN to Tx OUT, as unidirectional optical transmission is carried on simplex fiber strands.

To install the OSP SFP+ transceiver (not included):

Make sure the bail is pushed up, in the closed position.

Insert the OSP SFP+ transceiver into the relevant optical device SFP+ slot and push it in until it clicks.

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 the power

Connect the power cord to 675T/675R 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.
