1 Introduction

Welcome to Kramer Electronics (since 1981): a world of unique, creative and affordable solutions to the infinite range of problems that confront the video, audio and presentation professional on a daily basis. In recent years, we have redesigned and upgraded most of our line, making the best even better! Our 500-plus different models now appear in 8 Groups ^1 , which are clearly defined by function.

Congratulations on purchasing your Kramer TOOLS Cobra T2 Video / RS-232 Transmitter, which extends VGA and serial signals over ordinary Category 5 cable. This unit is field configurable for various video and serial options (see Appendix D for configuration settings).

The T2 series feature video and RS-232 signals on a single CAT 5 cable.

The package includes the Cobra T2 Video / RS-232 Transmitter and this user manual ^4 .

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

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 cables ^3 . You may also need 1/8" (3.5mm) audio cable, video cable with HD15 connectors, serial cable with DB9 connectors, and CAT 5 cable.

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 T2 in a location free from moisture and away from excessive sunlight and dust

Caution - No operator-serviceable parts inside unit.

Warning - Use only the Kramer Electronics input power wall adapter that is provided with this unit ^1 .

Warning – Disconnect power and unplug unit from wall before installing or removing device or servicing unit.

Warning –This equipment is not intended for, nor does it support, distribution through an Ethernet network. Do not connect these devices to any sort of networking or telecommunications equipment!

4 Setup and Installation

Data Mode Configuration

The Kramer Cobra T2 Video / RS-232 Transmitters are configured in full modem bidirectional serial modes. If you are using the daisy chain receivers or a CAT 5 matrix switch or CAT 5 distribution amp, this mode must be changed to uni-directional broadcast. To do this, configure the internal Serial Daughterboard (SDB) to change the transmitters and receivers serial mode operation (see Appendix E). This configuration should be done before making any cable connections and applying power.

Alternatively, remove the internal daughterboard and use the transmitters built in simplex serial option with the appropriate jumper changes.

With regard to connecting the cables:

• We recommend mounting and connecting all cabling to the Cobra T2 Video / RS-232 Transmitter components before applying power.
• Be sure that the CAT 5 cable you intend to use has been tested to comply with the T568B wiring specification (see Appendix A).

4.1 Making the Connections

This section contains figures showing connections with the specific Cobra 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 T2 must be connected to a Cobra R500-2 for the serial signals to function. You cannot use the serial option with a Cobra T2 and a Cobra R500-2 that is configured for simplex serial. Similarly, a Cobra T2 cannot be used with a Cobra R500A. Video modes may function normally, but 4th pair options will not.

At the transmitter end:

1. Connect the source video to the Cobra T2 Series transmitter video input port, which is an HD15 connector labeled VIDEO IN.
2. If desired, attach a local monitor via the local monitor port to LOOP OUT.
3. Make your audio or serial connections via the AUDIO/AUX I/O 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 (refer to the receiver user manual):

1. Connect the VIDEO OUTPUT HD15 connector to the display unit, and attach any audio (AUX I/O) and/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 display is powered ON).

4. Adjust video levels and skew compensation per appropriate receiver manual.

4.2 Connections on the Single-Port VGA/RS-232

The Single-Port Cobra T2 CAT 5 Video System with RS-232 supports video and full-modem serial (RS-232) signals over CAT 5 cable. You can also use the transmitters and receivers to make video-only connections without serial communications. Figure 1 shows the Single-Port Cobra T2 CAT 5 Video System with RS-232 Transmitter connections.

NOTE

Even though both transmitter and receiver units contain audio jacks, audio is not supported on the RS-232 version. Plugging in audio cables may interfere with the RS-232 serial communications.

NOTE

Serial communication mode is unidirectionally broadcast when using transmitters and daisy-chained receivers. In this mode, all other devices must be of the simplex serial type. For more information, contact Technical Support.

5 Solutions to Common Problems

In most cases, nearly every issue with the Cobra T2 CAT 5 Video System can be resolved by checking the CAT 5 termination and making sure that it's pinned to the TIA/EIA 568B wiring specification. However, there may be other problems that cause the system to not perform as it is designed. Below are solutions to the most common installation errors.

Problem:	No video signal at the transmitter local port or at the receiver.
Solution:	Check that both units are powered.Ensure receiver EQ adjustment is set correctly — turn knob slowly.Make sure the CAT 5 cable is terminated correctly per the TIA/EIA 568B wiring specification.Is the display device powered on and functioning?Check to ensure display settings (resolution, refresh rate, and so on) are compatible with input signal.In some cases, the video termination may be mismatched. The transmitters and receivers ship with 75-ohm termination as the default. To disable termination, seeAppendix B.
Problem:	Poor video quality.
Solution:	Have all receiver adjustments been finished?Ensure EQ adjustment is set correctly — turn knob slowly.Check all cable connections.The video signal’s refresh rate may be set too high. Reset to a lower refresh rate in your monitor-configuration menu.There may be a delay skew issue. See the section on Skew in the receiver manual.There may be a DDC compatibility problem. SeeAppendix G.
Problem:	Poor audio quality.
Solution:	Powered speakers are required. Make sure speaker power is ON.Check input source levels from the source device. Make sure the audio source is not overdriven or underdriven.Audio is summed left and right for “A” versions. If using a single channel, both audio inputs must be connected at the transmitter end for full audio gain. Audio is line level.S2 serial//audio units support full stereo line level. A high frequency noise may be heard if the CAT 5 cable from the transmitter is disconnected, or the transmitter is not powered up.This is normal and will disappear once a complete link connection is made.
Problem:	Serial communication doesn’t work correctly.
Solution:	Are the serial devices connected properly? Are the serial parameters correct for source/destination devices?Are the serial cables terminated correctly? If a null-modem cable is used, it must be placed at the receiver end.When using RS-232 transmitters or receivers in daisy chains, CAT 5 switches, or CAT 5 distribution amps, the serial signal is a unidirectionally broadcast mode only. In this mode, all other Cobra CAT 5 Video System devices must be the simplex serial type. For assistance, contact Technical Support.See Appendix E for Serial board settings. External switch for last unit in daisy chain.
Problem:	“Green shift” or “green washout” on multimedia signals.
Solution:	The standard video/serial model is designed to function with DC coupled signals in which the black level is referenced to 0 volts.Nearly all VGA cards function this way.Some media servers, however, provide AC coupled signals and can cause a green color shift in the video. This is a result of the sync clamping on the red and blue channels of the video/serial model.For five-component (RGB/H&V) AC coupled video, the Cobra CAT 5 Video System T2 Universal transmitter has been designed with full DC restoration capability.

Appendix B Setting Sync Signal Output Termination

In some cases, it may be necessary to disable the 75-ohm termination of the video outputs on the Cobra CAT 5 Video System units. This can be done by opening the case of each unit and installing jumpers on the circuit board. The settings disable/enable the 75-ohm termination on individual units. For instance, changing a transmitter termination affects the local monitor port only, it doesn't affect the receivers. Conversely, changing a receiver affects the output port of the receiver, not the transmitter. The following illustrations show the jumper locations for the Cobra T2 unit.

75-ohm sync termination:

To enable: Both jumpers OUT (Default)

To disable: Both jumpers IN

Figure 2: Setting Sync Signal Output Termination

Appendix C DC Restore to fix Green Shift of AC Coupled Signals

The standard Cobra product is designed to function with DC coupled signals with the black level referenced to 0 volts. Nearly all VGA cards function this way. However, some media servers or digital camera devices provide AC coupled signals and can cause a green color shift in the video. This is a result of the sync clamping on the Red and Blue channels in the Cobra. The

CobraT2 transmitter has been designed with full DC restore capability. A simple switch setting is all that is required.

The following diagrams show the switch location and settings for the Cobra Universal Transmitter assembly.

Note: Switch settings other than shown below may result in unpredictable performance and are not supported by Kramer.
