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 this entirety before running or terminating the wires to ensure proper operation and to avoid damaging equipment.

IMPORTANT! Wiring Guidelines

  • The use of patch panels, wall plates, cable extenders, kinks in cables, and electrical or environmental interference will have an adverse effect on 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 HDMI and DP 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.

LAN Port

The NetworkHD 400 Series LAN port is a 1GbE link for connection to a 1000BASE-T Ethernet device port. Refer to IEEE 802.3ab for official guidance on the Ethernet link. Cables must be tested to 100MHz across the entire link. 1000BASE-T uses the IEC 60603-7 8P8C modular connector.

RS-232 Port

The NHD-400-DNT-TX uses a 3-pin phoenix connector. The RS-232 communication does not utilize hardware flow control. Please ensure that the data flow direction is observed (i.e. the NetworkHD RS-232 TX pin is connected to the attached device’s RX pin)–pinouts on 3rd-party equipment will vary– please check the relevant device documentation.

WyreStorm Connector 3rd Party Device
Pin 1 TX (Transmit) —> To —> RX (Receive)
Pin 2 RX (Receive) —> To —> TX (Transmit)
Pin 3 G (Ground) —> To —> G (Ground)

Infrared Ports

Using WyreStorm infrared emitters and receivers is the best way to ensure that most IR coding formats are transmitted and received by the NetworkHD system. Other 3rd party emitters may be compatible; however, these devices must operate in the same manner as the WyreStorm devices.

Due to differences in IR across 3rd party control systems their IR ports should never be connected directly to a NetworkHD system as an incompatibility may exist. WyreStorm offers a cable that compensates for IR electrical signal differences, as well adjusts for differences in the pins used within the port. Refer to the CAB-IR-LINK product page for more information.

An IR TX (transmit) cable uses a 3.5mm TS mono jack plug.An IR RX (receive) cable uses a 3.5mm TRS stereo jack plug that outputs +5V DC to power the included IR receiver module.

Audio Ports

The NHD-400-DNT-TX both accepts and generates single-ended (unbalanced) “consumer” level analog audio with nominal line levels at -10dBV. Audio ports accept cables that use a 3.5mm TRS stereo jack plug.

Setup and Configuration

IMPORTANT! Installation Guidelines

  • Do not connect the power supply until all Network HD devices are connected to the network switch.
  •  Network HD 400 Series uses either DHCP (where a DHCP server is reachable) or stateless address autoconfiguration (auto-IP) to assign link-local IP addresses in the range of 169.254.x.x to encoders and decoders out of the box. Your PC must be set to an address in this range in order to discover the encoders, decoders and NHD-000-CTL.
  • In order to configure the Network HD encoders and decoders, the “AV” port on the NHD-000-CTL MUST be connected to the same LAN/VLAN and Subnet as the NHD encoders and decoders.
  • In order for the devices in the system to be controlled via a 3rd party controller on a different VLAN, either the “CONTROL” port on the NHD-000- CTL can be connected to the other LAN/VLAN and Subnet containing the control system directly (isolated approach, recommended) or the use of a router must be employed to route the data between different subnets by using the NHD-000-CTL “AV” port only.
  • The NHD-000-CTL’s two Ethernet interface ports are designed to reside in different Subnets and cannot have IP addresses/subnet masks that cause an “overlap” of the Subnets assigned to them. When using a single Network or VLAN, for example when using Network HD Touch—do not connect both ports—only use the “AV” port of the NHD-000-CTL.
  • The Dante encoder contains its own MAC address and IP address. The configuration of the Dante encoder can be manipulated using official Audinate software tools.
  • For connection to Dante networks, the Dante encoder network traffic can optionally be assigned to a separate VLAN with the use of MAC-based VLAN association—a common feature found on most L2 managed switches. For more information, visit wyrestorm.com.

Installation and Connections

  1. Install NHD devices to allow airflow through the product—when rack mounting, WyreStorm recommends using the NHD-000-RACK4 kit. The install location should be dry, well ventilated and guaranteed to maintain the mandatory operating temperature range of the product.
  2. Connect sources to the Network HD encoders using a HDMI cable from a quality brand, such as WyreStorm Essentials ensuring a firm port connection.
  3. Connect the HDMI display to the Network HD decoders using an HDMI cable from a quality brand, such as WyreStorm Essentials ensuring a firm port connection.
  4. Connect Network HD encoders, decoders, and CTL to the network switch using well terminated and tested category cable, while ensuring compliance with IEEE 802.3ab (for CTL, encoder, and decoder 1GbE ports).
  5. Optionally, connect the RS-232 port to equipment following the RS-232 pinout section in the appropriate Quickstart Guide.
  6. Optionally, connect the analog audio ports to equipment following the audio pinout section in the appropriate Quickstart Guide.

Download the Network HD Switch Mapping Worksheet from any Network HD product page to keep track of MAC addresses, device and alias names forlater reference. This will aid the setup process in Network HD Console and help with any reconfiguration or troubleshooting.

Network HD Console Configuration

In addition to the steps below more information on configuration can be found in the Network HD Installation Guide.

  1. Ensure that a correctly configured network switch has been setup in advance. Guides are available from the WyreStorm website.
  2. Connect a computer running Windows™ to the same LAN/VLAN as the Network HD components and ensure its IP is within the same subnet as the Network HD default 169.254.x.x IP addresses. Ensure that no DHCP server will allocate addresses. The NHD-000-CTL “AV” port is set to a static address of by default – do not choose this address for your PC.
  3. Power On the NHD-000-CTL by connecting to a PoE switch or by using the included DC power adapter.
  4. Power On the NHD devices by connecting the device to a PoE switch or by using the optional power adapter, PSU-12V-1A, available separately.
  5. Once all devices have booted, open the WyreStorm Management Suite (Available from the WyreStorm website) and launch the Network HD Console software and press Search.Note: If a no devices are discovered, verify that encoders/decoders, CTL and PC are within the same subnet scope and within the same range of the CTLs “AV” Port and disable or create an exception for the Network HD Console in Windows Firewall or any 3rd-party firewall/malware/antivirus software.
  6. Configure the system as per the instructions in the Network HD Installation Guide. Right Click on the 400 Series device to see its available options, including setting the device’s IP address and setting an Alias name. You will also find other configuration options under the Batch Settings window.Note: If a 3rd Party control system with a WyreStorm driver for Network HD is going to be used, the encoders must use the Alias prefix IN1, IN2, etc. This also applies to decoders, OUT1, OUT2, etc. For example, IN1-Satellite Receiver 1.
  7. Upload to the configuration to the NHD-000-CTL by right clicking the CTL in the Other Devices section and selecting Upload.
  8. Configure the scaling and HDCP values of each decoder based on the requirements of the content and display using the settings found in the Video tab in the Batch Settings screen.


Verify that all NHD devices contain the latest version of firmware. This will ensure that all devices are up to date and working at their highest performance level.
