Information and Parts Required for Installation

This transmitter requires connection via RS-232 or Ethernet in order to configure functions such as EDID. Ensure that the following items are on hand before proceeding with the installation.

  •  PC or Mac
  • Telnet and Terminal software such as PuTTY
  •  USB COM Port Adapter (Not Included)
  •  WyreStorm Part: CAB-USB-3PIN
  •  Network router and/or switch if using IP telnet for configuration.
  • The latest version of the SW-740-TX API for advanced configuration is not covered in this document.

Basic Wiring Diagram

Wiring and Connections

WyreStorm recommends that all wiring for the installation is run and terminated prior to making connections to the switcher. Read through this section in its entirety before running or terminating any wires to ensure proper operation and to avoid damaging the equipment.

IMPORTANT! Wiring Guidelines

  •  The use of patch panels, wall plates, cable transmitters, kinks in cables, and electrical or environmental interference will have an adverse effect on the signal transmission which may limit performance. Steps should be taken to minimize or remove these factors completely during installation for best results.
  • WyreStorm recommends using pre-terminated VGA, HDMI, and USB cables due to the complexity of these connector types. Using pre-terminated cables will ensure that these connections are accurate and will not interfere with the performance of the product.
  • This product contains a USB-C connection that can be used as an audio/ video input. When using this connection verify that the USB-C cable used supports audio/video functionality as not all USB-C cables support this requirement.

Audio ConnectionsAudio InThe audio connections use a 3.5mm (1/8in) TRS Stereo Jack.

Audio OutThe audio connections use a 3.5mm (1/8in) TRS Stereo Jack.

Control Communication

RS-232 WiringThe SW-740-TX uses a 4-pin RS-232 with no hardware flow control. Most control systems and computers are DTE where pin 3 is RX, this can vary from device to device. Refer to the documentation for the connected device for pin functionally to ensure that the correct connections can be made.IR WiringThe 4-pin IR connector can be used to either transmit or receive IR signals, based on the type of cable and pinout you use. The IR emitter or receiver being used must support 5v for proper operation.

Contact In/Tally OutContact connections are provided to allow for switching sources and feedback to a contact closure button on a desk or wall plate.

PIR SensorContact connections are provided to allow for automatic triggering of input switching or display power.

Setup and Configuration

The SW-740-TX is configured using RS-232 or IP commands for Output Resolution, and EDID. Follow these steps to properly configure the transmitter based on the system requirement.Note: The steps and information provided in this QSG are for the basic operation of the transmitter out of the box. Refer to the SW-740-TX API for full configuration settings.

  1. Assign a Static IP Address to ensure proper communication on an IP Network.
  2.  Set EDIDs to be used at each input of the device. See Configuring Input EDIDs

Communication SettingsThe SW-740-TX contains a web UI that can be accessed by connecting to a network and entering the IP address. We recommend that the IP address be changed from default before accessing the web UI for the first time.

No or Poor Quality Picture (snow or noisy image)

  • Verify that power is being supplied to the transmitter and receiving device.
  • Verify that all HDMI and HDBaseT connections are not loose and are
  • functioning properly.
  • Verify that the HDBaseT cable is properly terminated following EIA568B
  •  standard.
  • Verify that the output resolution of the source and display is supported by
  •  this transmitter.
  •  Configure EDID Settings to a lower resolution.
  •  If transmitting 3D or 4K, verify that the HDMI cables used are 3D or 4K rated.

No or Intermittent 3rd party Device Control

  •  Verify that the IR, RS-232, and Ethernet cables are properly terminated following the Wiring and Connections section.

Relays Not Functioning

  • Verify the polarity of the relay connections.Troubleshooting Tips
  • WyreStorm recommends using a cable tester or connecting the cable to other devices to verify functionality.
