IR – Dual 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-70R or the SY-HDBT-70T 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 or RTS/CTS as required. The MODE switch on both the extender units must the set to
Norm to allow RS232 control signals to pass between them. All standard RS232 baud rates
up to 115.2 K baud are supported without needing to set any switches or special
configuration options.
The RS232 port also supports RTS/CTS flow control using the RT/CT connections. If RTS/CTS
flow control is not required, then the RT/CT connections could be used as a second RS232
port.
ARC, S/PDIF and Stereo Audio (L/R)
These extenders also support ARC from the receiver to the transmitter for sending the off-
air broadcast audio signal down to an ARC sound receiver. The ARC70 set will automatically
select one of the following three audio modes:
1.
HDMI ARC – ARC mode is selected when the 3.5mm jack sockets are left unused.
2.
S/PDIF – Optical audio mode is selected when the 3.5mm jack socket detects
that an optical fibre is connected.
3.
Stereo Analogue Audio – Analogue audio is selected when the 3.5mm jack
socket detects that a jack plug is connected.
PoC
The SY-HDBT-70 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.
