Quick Start
Pathfinder 4.0 MF could be used flexibly as either transmitter or receiver to
support a couple of different installations and applications, because of a local
HDMI Out port built in.
Application 1: Chain-type Connection
In Application 1, Device 1 and Device 2 are used as transmitter to connect
source, while Device M and Device Z are dedicated receivers to connect
multiple displays.
Application 2: Chain-type Connection with Local Monitor

875800 User manual
TLS electronics GmbH Contact: info@tls-electronics.de 10
In Application 2, each Pathfinder in the chain has its local HDMI Out connected
with local monitor, so as to show forward or local source once it’s selected in the
chain. Please note only backward devices could display forward sources, while
forward devices can not have their local monitor to show backward sources.
Application 3: Ring-type Connection
In Application 3, the last Device Z has its HDBT OUT connecting to HDBT IN of
the first Device 1. As a result, each source selected could be displayed by any
monitor in the chain, and fix the issue in chain-type connection that backward
sources can not be displayed in forward monitors.

875800 User manual
TLS electronics GmbH Contact: info@tls-electronics.de 11
Application 4: Grouping Mode
In Application 4, Device 1 and Device 2 work in Group 1, while Device M and
Device Z work in separate Group Z. Devices in different groups can not select or
display sources from other groups. Grouping mode is simply activated by Telnet
API or clicking the Daisy-chain Grouping option on the WEB GUI of device, then
the video will stop to be outputted to backward devices.
For example, set Device 2 in grouping mode to make Device 1 and Device 2
work as Group 1, then Device 3 and all backward devices are in the other group;
set Device 2 and Device 4 in grouping mode to make Device 1 and Device 2 in a
group, Device 3 and Device 4 work in a group, Device 5 and backward devices
in the other group (More details please check Page 16.) Both Chain-type and
Ring-type connection could support grouping mode.
Before set up, please take care of below steps:
1. Connect a PC to each device by Ethernet port, log in their WEB GUI to set
static IP address and alias name for every device. (Please check Page 13 to
learn how to log in WEB GUI.)
2. Connect all devices by HDBaseT ports through Cat cable, make a Chain-type
connection firstly and feed LAN access to Ethernet port of any device. Do not
make Ring-type connection directly with LAN access, otherwise there will
be LAN conflicts and LAN control disabled.
3. Log in WEB GUI of the first device in the chain, input total quantity of devices
cascaded within Daisy-chain Sequence and then click Start Sequence.

875800 User manual
TLS electronics GmbH Contact: info@tls-electronics.de 12
(More details please check Page 16 Daisy-Chain Sequence).
4. Connect the HDBT OUT of the last device to the HDBT IN of the first device,
log in WEB GUI of the first device to click Start Sequence again, then Ring-type
connection is set up correctly.
Any Pathfinder reset, removed, replaced or newly added in the chain,
please follow above instruction to configure them again.
Connections and Installation
1. Connect the HDBT OUT port of Pathfinder 1 to the HDBT IN port of
Pathfinder 2, connect the HDBT OUT port of Pathfinder 2 to the HDBT IN
port of Pathfinder 3, and follow to daisy-chain multiple Pathfinder through
HDBT ports by Cat cable.
2. Using quality HDMI/DP/VGA cables to connect different sources (such as
Laptop, PC, Blu-ray, satellite/cable TV, etc.) to HDMI IN/DP IN/VGA IN port
of Pathfinder.
3. Using quality HDMI cables to connect the HDMI display device (such as
Projector, Monitor or TV) to the HDMI OUT of Pathfinder.
4. Connect a controller such as IP-based touch panel to an Ethernet port of
Pathfinder, or Contact Closure-based keypad to the Select/KEY/LED ports
to control. Circuit diagram of Contact Closure ports including SELECT, KEY
and LED (2,5 - 3,3V – 5 - 8 mA) without any resistors as shown:
5. Power on all devices. Use the Select Button, Contact Closure, WEB GUI or
