Introduction

1 Introduction

Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we have redesigned and upgraded most of our line, making the best even better! Our 1,000-plus different models now appear in 11 groups1 that are clearly defined by function.

Congratulations on purchasing your Kramer Cobra R1300A Video / Audio Receiver and/or Cobra R1300S2 Universal Receiver. The Kramer Cobra Series System extends video, audio and serial signals over ordinary Category 5 cable. This manual covers the Cobra R1300A Video / Audio Receiver and the Cobra R1300S2 Universal Receiver. These units are field configurable for various video, audio and serial options. See Appendix B for configuration settings. A versions support video and audio. S2 series feature video, stereo audio and RS-232 signals on a single CAT 5.

The Kramer Cobra R1300A Video / Audio Receiver and Cobra R1300S2 Universal Receiver feature optional integrated skew compensation that can be varied in 2 ns increments to 65 ns total per color channel to cancel the effects of skew in Category cables. This feature allows you to use CAT 5e and reduced-skew CAT 6 cables to lengths up to 1300ft. For information on the respective transmitter unit, refer to the appropriate manual included with the transmitter. All models support refresh rates/resolutions up to 1920 x 1200 @ 60 Hz to 1300 feet (396m).

The package includes the Cobra R1300A Video / Audio Receiver or the Cobra R1300S2 Universal Receiver, an external power supply, and this user manual2.

The Kramer Cobra series products are not compatible with Kramer non-Cobra

series products.

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

 Use Kramer high performance high resolution cables1. You may

also need CAT 5 cable2

3 Overview

Our Kramer Cobra series products are compatible with CAT 5/5e/6 data cabling as well as skew free CAT 5/5e cabling manufactured for video applications. Note that some skew free CAT 5 is specific to a particular vendor and is not compatible with our products. Ensure any skew free CAT 5 cable is non-proprietary prior to purchase / installation.

We recommend using our Kramer Cobra ultra low skew cable—BC-HDTP (solid bulk) or BCP-HDTP (solid plenum bulk)—available in lengths of 700' (210m) and 1300' (390m).

CAT 6 cable, due to the manufacture method, can exhibit much greater skew than standard CAT 5/5e and may require skew compensation beyond what the standard product offers. Contact Kramer Electronics for assistance.

CAT 5/5e/6 cabling for this product must be pinned to the TIA-EIA T568B wiring specification (see appendix A). We also highly recommend that all CAT 5 cables be pre-terminated and tested. Cables terminated on-site or in an existing infrastructure should be tested before use to ensure compliance with the TIA-EIA T568B specification. Using incorrectly terminated CAT 5 cables can damage this product.

Achieving the best performance means:

 Connecting only good quality connection cables, thus avoiding

interference, deterioration in signal quality due to poor matching, and elevated noise levels (often associated with low quality cables)

 Avoiding interference from neighboring electrical appliances that may

adversely influence signal quality and positioning your Cobra R1300A / R1300S2 in a location free from moisture and away from excessive sunlight and dust

2 In addition, you may also need audio cable with RCA jacks, serial cable with DB9 connectors, and video cable with HD15

connectors

Setup and Installation

4 Setup and Installation

4.1 Data Mode Configuration

The serial signal is 3 wire TX, RX, GND and does not support full modem signals. Baud rates for the S2 series are fixed at 9600. Simplex modes are supported without jumper or other changes by simply using the TX signal only. S2 units require no configuration.

4.2 Making the Connections

This section contains figures showing connections with the specific Cobra R1300A / R1300S2 series models. In general, however, the connection and

setup procedure at both transmitter and receiver ends is as follows:

NOTE: all units must be the same type for all supported features to function correctly. For example, a Cobra transmitter set for R/L summed audio must be connected to an R1300A / R1300S2 set for R/L summed audio. Similarly, a Cobra T2 cannot be used with an R1300A / R1300S2. Video modes may function normally, but 4th pair options will not.

At the transmitter end (refer to the transmitter user guide):

1. Connect the source video to the Cobra Series transmitter video input port,

which is an HD15 connector labeled SOURCE IN or VIDEO IN.

2. If desired, attach a local monitor via the local monitor port to LOCAL OUT.

3. Make your audio/serial connections via the audio connector or DB9 connector as appropriate.

4. Connect the CAT 5 cable to the transmitter.

5. Apply power on the transmitter. The LED should light and, if there is a local monitor attached, a video image should appear on the monitor’s screen.

At the receiver end:

1. Connect the VIDEO OUT HD15 connector to the display unit and attach any audio (AUDIO/AUX I/O) or serial connections (RS-232) depending on the model of the Cobra CAT 5 Video System.

2. Connect the CAT 5 cable to the LINK INPUT connection. If daisy chaining units, connect the output CAT 5 cable to the LINK OUTPUT connection.

3. Apply power. The LED should light and video should appear on the display (make sure that the display is powered ON).

4. Adjust video levels and skew compensation.

5. Mount the R1300A / R1300S2 in a location that ensures the ventilation holes and fan are not blocked.
