2 611T, 611R - Getting Started

2 Getting Started

We recommend that you:

•Unpack the equipment carefully and save the original box and packaging

materials for possible future shipment

•Review the contents of this user manual

Go to http://www.kramerelectronics.com to check for up-to-date

user manuals, application programs, and to check if firmware

upgrades are available (where appropriate).

2.1 Achieving the Best Performance

To achieve the best performance:

•Use only good quality connection cables (we recommend Kramer high-

performance, high-resolution cables) to avoid interference, deterioration in

signal quality due to poor matching, and elevated noise levels (often

associated with low quality cables)

•Do not secure the cables in tight bundles or roll the slack into tight coils

•Avoid interference from neighboring electrical appliances that may adversely

influence signal quality

•Position your Kramer 611T, 611R away from moisture, excessive sunlight

and dust

This equipment is to be used only inside a building. It may only be

connected to other equipment that is installed inside a building.

4 611T, 611R - Overview

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.
