and HDMI display(s).
2. Connect your HDMI source to the Transmitter's
HDMI In connector.
3. Optional: Connect your HDMI display to the
Transmitter's HDMI Out connector with an HDMI
cable (HDMI cable not included) for local
monitoring of the HDMI signal.
4. Optional: Connect the IR cable to the Transmitter's
IR port. See IR Application on page 10 for proper
cable connection.
5. Connect a CAT6 cable between the Transmitter's
RJ45 Out and Receiver's RJ45 In. For 1-to-many
setups, connect the TX and all RX's to the Gigabit
switch.
6. ConnectyourHDMIdisplay to the Receiver'sHDMI
Outconnector with anHDMI cable (HDMI cablenot
included).

EDID Management
• The default EDID is 4K @60Hz (3840x2160)
• If there's a display connected to the HDMI loopout
on the Transmitter (TX), EDID learning of this
display will occur automatically and override the
default EDID
• 4K to 1080p auto downscaling is supported on the
Receiver (RX). This happens when there's a 4K
display connected to the TX's HDMI loopout and a
1080p display connected to the RX
Important Notes
• A dedicated Gigabit switch or cascading switches
of the same LAN/VLAN is recommended, due to
high bandwidth usage
• When cascading switches, do not mix Fast Ethernet
(100Mbps) with Gigabit switches. Only use Gigabit
switches
• Supports up to 100 Receivers (RX). The bandwidth
to each Receiver is 120Mbps, regardless of the
number of RX's used
• As long as our devices are in the same LAN or
VLAN, they will see with each other. There is no
need to configure the IP addresses of our devices
• Only 1 Transmitter (TX) is supported within a LAN
or VLAN
• Keep our devices separate from other network
devices to avoid network traffic

RS232Passthrough
Connect the TX's or RX's RS232 port to your control PC's
serial port using an RS232 cable.
COM Port Setting
RS232 Serial Line Wiring Diagram
Make sure the RS232 serial lines are firmly connected and
the serial data lines are oriented correctly. Note: If your
RS232 serial device does not communicate, try to change
the order of the TXD and RXD lines.
