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.

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.

Tip:

Anode

Sleeve: Cathode (IR Signal)

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. 

Tip:
Ring:

IR Signal

+5V DC

Sleeve: Ground (GND)

RS-232 Wiring

The RXV-70-4K-G2 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.

3rd Party Device

Pin 1 TX (Transmit) ---> To ---> RX (Receive)
Pin 2 RX (Receive)

---> To ---> TX (Transmit)

Pin 3 G (Ground)

---> To ---> G (Ground)

Troubleshooting

No or Poor Quality Picture (snow or noisy image)

•  Verify that power is being supplied to the transmitter and receiver.
•  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 extender.

•  If transmitting 3D or 4K, verify that the HDMI cables used are 3D or 4K rated.
•  Verify that all source and HDBaseT 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.
