Frequently Asked Questions - EXF-300-H2 WyreStorm

What is the maximum transmission distance?

The EXF-300-H2 can transmit HDMI signals up to 300m (984ft) over OM3 multimode fiber at all supported resolutions.

Can I transmit IR and RS-232 simultaneously?

No, only one signal type (IR or RS-232) can be transmitted at a time over the fiber cable. Configure both TX and RX accordingly.

Why is there no picture or a snowy image?

Check that both transmitter and receiver are powered, the fiber cable is properly terminated, and the HDMI cables are rated for the resolution (e.g., 4K). Loose connections can also cause issues.

What video resolutions are supported?

Resolutions up to 4096x2160p@60Hz 4:4:4 8bit and 3840x2160p@60Hz 10bit HDR are supported, depending on fiber quality and length.

How do I connect RS-232?

Use the 3-pin Phoenix connector. Connect TX of the WyreStorm to RX of the 3rd party device, RX to TX, and ground to ground. Refer to the pinout in the manual.

What IR accessories are compatible?

WyreStorm recommends using their infrared emitters and receivers. For 3rd party devices, use the CAB-IR-LINK cable to ensure compatibility.

Does this extender support HDCP 2.2?

Yes, both HDMI and fiber ports support HDCP 2.2 and EDID pass-through.

How is the unit powered?

Each unit (transmitter and receiver) requires a 12V DC 0.5A power supply. A dual USB-A to locking DC plug is included.

What is the warranty period?

WyreStorm offers a 5-year limited warranty against defects in material and workmanship.

Can I use this extender with a CATx cable instead of fiber?

No, the EXF-300-H2 is specifically designed for OM3 multimode fiber cables. It uses SFP+ modules, not Ethernet.

Note: RS-232 and IR signals cannot be transmitted simultaneously over OM3 if both are connected. Use either RS-232 or IR to avoid data conflicts.

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 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.

OM3 Fiber SFP+ Guidelines

The EXF-300-H2 is designed to work with SFP+ OM3 MM fiber cables providing a distance of 300m/984ft for all resolutions. This operation can be affected by how the cables are terminated and routed within an installation. Care should be taken when terminating and routing based on the following guidelines.

• Fiber cable has a bend radius of 6.0cm/2.4in, when routing never exceed this radius as damage to the fiber core can occur.
• Fiber core ends should be inspected for damage prior to terminating. Any scratches or blemishes can affect the performance of the connection.
- Never touch the end of the fiber core with bare hands so that any oils or dirt can be transferred to the surface of the core.
• Refer to the guidelines and connection parameters from the fiber cable manufacturer for more specific information regarding the cable being used.

IR TX/RX Guidelines

• Using WyreStorm infrared emitters and receivers is the best way to ensure that most IR coding formats are transmitted and received Other 3rd party emitters and receivers can be used; 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 voltage differences as well adjusts for differences in the pins used within the port. Refer to the CAB-IR-LINK product page for more information.

IR TX Port Pinout

Connection for IR TX (transmit) uses a 3.5mm (1/8in) mono plug.

IR RX Port Pinout

Connection for IR RX (receive) uses a 3.5mm (1/8in) stereo jack that outputs +5V DC to power the included IR receiver.

RS-232 Wiring

The EXF-300-H2 uses a 3-pin RS-232 with no hardware flow control. Most control systems and computers are DTE where pin 2 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.

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)

Setup and Configuration

RS-232/IR Over Fiber

The EXF-300-H2 can transmit RS-232 or IR over fiber bidirectionally, however it can only send one or the other. The following settings must be made on both the TX and RX for the type of signal that will be sent within the installation.

Send and Receive RS-232

Send and Receive IR

EDID Configuration

This extender uses EDID pass-through from the display to the source. No configuration is required for EDID settings.

Troubleshooting

No or Poor-Quality Picture (snow or noisy image)

• Verify that power is being supplied to the transmitter and receiver.
• Verify that the fiber cable is properly terminated.
• Verify that the output resolution of the source and display is supported by this extender.
• If transmitting 3D or 4K, verify that the HDMI cables used are 3D or 4K rated.
• Verify that all source and fiber connections are not loose and are functioning properly.

No or Intermittent 3rd party Device Control

• Verify that the RS-232/Ethernet cables are properly terminated.
• Verify that emitters/receivers are compatible with WyreStorm IR.
• If using an IR control system, verify that it is connected using the CAB-IR-LINK cable.
