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.
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
for details on setting RS-232 modes.
3rd Party Device
Pin 1 TX (Transmit) ---> To ---> RX (Receive)
Pin 2 RX (Receive)
---> To ---> TX (Transmit)
Pin 3 G (Ground)
---> To ---> G (Ground)
WyreStorm Connector
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 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
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)
