Using the HDBT HDMI Extenders
HDMI Extender
Connect a HDMI source to the HDMI IN socket on the HDBT-70ST and connect a HDMI
display to the HDMI OUT socket on the HDBT-70SR. Connect a Cat6 UTP cable to the HDBT
sockets of both the transmitter and receiver units. Connect the 48V Power supply to either
the Transmitter or the Receiver unit.
Status LEDs
The LINK LED indicates the link status of the transmitter and receiver units, solid ON for a
successful link and off when a link cannot be established.
The green STATUS LED indicates that the HDBaseT signal is being transferred between the
transmitter and the receiver.
The SIGNAL LED on the transmitter indicates that HDMI data is being received from the
HDMI source. For the receiver it indicates that HDMI data is being sent to the HDMI display
device. The SIGNAL LED will remain OFF for any of the following conditions:
1. The HDMI source is not outputting data, the HDMI cable is either not connected
or it is faulty.
2. The HDMI display is not connected or powered up, or the HDMI cable is faulty.
3. The HDMI display is not set to use its HDMI input.

IR –Bidirectional
To use the IR Extender option, point your IR remote control device at the IR detector
connected to the IR IN socket of either the SY-HDBT-70SR or the SY-HDBT-70ST as required.
An IR emitter must also be connected to the corresponding transmitter or receiver IR OUT
socket. Locate the IR emitter close to the device you wish to control. All IR control functions
are now possible from the remote location.
RS232 –Bidirectional
To use the RS232 Extender option, connect the RS232 equipment to the RS232 terminal
blocks with the cables provided and ensure that any RS232 handshake modes are set to
none. The MODE switch on both the extender units must the set to Oper to permit RS232
control between them. The SY-HDBT-ECO-70P Extender set supports all standard RS232
baud rates up to 115.2 K baud without setting any switches or special configuration options.
PoC
The SY-HDBT-ECO-70P Extender set have a Power over Cable (PoC) capability, allowing both
the Transmitter and Receiver units to be powered using only one power supply. The set can
be powered from either the Transmitter side or the Receiver side.
For best results, use only solid copper cat6 cables.
Mode Switch
The MODE switch should be set to Oper to permit transmission of RS232 signals between
the two extenders. The Prog setting is only used should the SY-HDBT-70ST or the SY-HDBT-
70ST require a field upgrade.

RJ-45 Wiring
Both connectors must be wired identically.
HDBaseT signals will not pass through any Ethernet device, the HDBaseT port on the SY-
HDBT-70ST must be connected directly to the HDBaseT port on the SY-HDBT-70SR.
Please do make sure that the Cat6 cable uses 4 pairs of 23AWG solid copper wires. Do not
use inferior copper clad cables as these exhibit higher resistances.

Troubleshooting
Problem
Possible Cause
Power LED is off
Check that the correct power supply as provided with the
product is being used.
Check the PSU connections and ensure that the PSU is switched
on.
If the PSU is at the other end of the RJ-45 cable, check that the
cable is correctly wired and is connected to the local unit.
LINK LED is off
Check that the RJ-45 cable between the transmitter and
receiver is connected with a direct connection and within the
specified distance.
Check the terminating connectors are wired correctly.
IN or OUT LED is off
For the transmitter:
Check that the LINK LED is on.
Check that the HDMI source is connected to the HDBT-70ST.
Check that the HDMI source is powered.
For the receiver:
Check that the LINK LED is on.
Check that the HDMI display is connected to the HDBT-70SR.
Check that the HDMI display is powered.
Check that the HDMI display is set to use its HDMI input.
RS232 is not being
transmitted
The MODE switch must be set at Oper on both the transmitter
and the receiver units to allow RS232 data to pass between
them.
