Frequently Asked Questions - EX-100-H2-EARC WyreStorm

What is the maximum transmission distance for 4K video?

Up to 70m (230ft) over Cat6 and up to 100m (328ft) over Cat6a/7 cable. Use shielded cables for best performance.

Does the EX-100-H2-EARC support eARC audio?

Yes, it supports eARC (enhanced Audio Return Channel) for high-bandwidth audio formats like Dolby Atmos and DTS:X. The LED indicates solid for eARC or flashing for standard ARC.

What HDMI cables should I use?

WyreStorm recommends using pre-terminated 4K-rated HDMI cables for 4K signals. For 1080p, standard HDMI cables work. Ensure cables are not damaged or kinked.

How do I configure the audio mode using dipswitches?

Power off both transmitter and receiver. Set the dipswitches to desired mode (eARC default, ARC, S/PDIF passthrough, or TX de-embedding). Then power on. Refer to the manual for exact switch positions.

Can I control the extender via IR or RS-232?

Yes, the extender supports bidirectional IR (with included receiver and emitter) and RS-232 control. Use 3.5mm mono plug for IR TX and stereo jack for IR RX. RS-232 uses a 3-pin Phoenix connector.

Does the extender require power at both ends?

No. The transmitter powers the receiver via PoE (Power over Ethernet) over the AVX link. Only the transmitter needs the included 12V DC 3A power supply.

What audio formats are supported over eARC and S/PDIF?

eARC supports PCM 2.0/5.1/7.1, Dolby Digital, Dolby Digital Plus, Dolby TrueHD/Atmos, DTS, DTS HD, DTS HD Master Audio, DTS:X. S/PDIF supports PCM 2.0, Dolby Digital, DTS 5.1.

Why is there no picture or a snowy image?

Check power to both units, verify AVX cable termination (EIA568B), ensure source/display resolutions are supported, use 4K-rated HDMI cables, and check all connections are secure.

What is the end-to-end latency of this extender?

The latency is exceptionally low at 10 microseconds (μs), suitable for real-time applications like gaming.

Does the warranty cover the product?

WyreStorm offers a 5-year limited warranty against defects in materials and workmanship. Refer to the product warranty page for details.

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 it's 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 the use of shielded category cable to minimize signal noise and interference.
• WyreStorm recommends using pre-terminated HDMI 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.

RS-232 Wiring

The EX-100-H2-EARC 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. Refer to RS-232 Mode Settings for details on setting RS-232 modes.

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)

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 by the system. 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.

eARC/ARC LED

The EX-100-H2-EARC shares one LED to signify whether the extender is transmitting an ARC or eARC signal. Based on the transmission, the LED behavior changes as below.

Solid: eARC audio is transmitting

Flashing: ARC audio is transmitting

Dipswitch Settings

The dipswitches on the TX and RX allow for changing the audio transmitting mode. Use the table to the right to configure the extender's audio mode based on the application's requirement.

When setting a dipswitch setting, power off both the transmitter and receiver before making a change. Once set, the units can be powered back on.
