Frequently Asked Questions - 611R Kramer

How do I connect the Kramer 611R extender?

Connect your video source to the BNC input and audio source to the RCA inputs. Run a single coax cable (RG-59) to the receiver unit. Connect the receiver's outputs to your display and speakers. Power both units with 12V DC.

What type of cable is required for the 611R?

Use RG-59 coaxial cable for video and audio transmission. For best results, keep cable runs under 300 meters.

Does the 611R require external power?

Yes, both the transmitter and receiver need a 12V DC power supply. The unit includes a 2-pin terminal block for connection.

Why is there no video output?

Check that the coax cable is securely connected and not damaged. Verify the power supply is working. Ensure the source device is outputting a composite video signal.

Can I use the 611R with HDMI sources?

No, the 611R is designed for composite video (BNC) and stereo audio (RCA). To extend HDMI, use a dedicated HDMI extender.

What is the maximum transmission distance?

The 611R can transmit video and audio up to 300 meters (984 feet) over RG-59 coaxial cable.

How do I mount the 611R in a rack?

The unit comes with rackmount ears. Attach them to the sides and secure to a standard 19-inch rack using screws.

What do the LED indicators mean?

The power LED lights when the unit is receiving power. The signal LED indicates a valid video input. If off, check the source and cable.

3 Overview

The 611T and 611R are a high-performance fiber optic transmitter and receiver for composite video signals. The 611T transmitter converts a composite video signal into a fiber optic signal and the 611R receiver converts the fiber optic signal back into a composite video signal.

More specifically, the 611T, 611R feature:

• 55MHz (-3dB) bandwidth
• Level (gain) and EQ (peaking) controls
• A range of 5km (3.1mi) using multi-mode fiber optic cable

4 Connecting the 611T, 611R

Always switch off the power to each device before connecting it to your 611T, 611R. After connecting your 611T, 611R, connect its power and then switch on the power to each device.

To connect the 611T, 611R as illustrated in the example in Figure 3:

1. On the 611T, connect a composite video source (for example, a video player) to the INPUT BNC connector.
2. On the 611R, connect the OUTPUT BNC connector to a composite video acceptor (for example, a video recorder).
3. Connect a fiber optic cable from the TO FIBER connector on the 611T to the FROM FIBER connector on the 611R.
4. Connect a 12V DC power supply to each of the units (not shown in the illustration).
5. As needed, adjust the HF and GAIN trimmers on each unit with a small screwdriver.
   The units come pre-adjusted from the factory for optimum performance and transparent operation. Adjustment is not normally required if all cables and connectors are working properly.
