RJ-45 Wiring
Both connectors must be wired identically.
HDBaseT signals will NOT pass through any Ethernet device, the HDBaseT port on the SSH70-T
must be connected directly to the HDBaseT port on the SSH70-R.
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 much higher resistances.
Test Pattern and Keep-Alive Features
The SSH70 extenders provide a built-in Test Pattern generator for verifying the integrity of
connections from the transmitter through to the display device. Several test patterns at
different resolutions are provided. See
Test Pattern
in the
RS232 Control Commands
section.
Test pattern is enabled when the front panel switch on the transmitter is set to TP.
The
Video Keep-Alive
feature also uses the saved test pattern setting, ensuring a video signal is
always present at the receiver HDMI output in the event of input video loss. This mode can
also have a timeout value to disable the test pattern after a programmable of time up to 4
hours.
See
Video Keep-Alive
in the
RS232 Control Commands
section.
Down-Scaling
The SSH70 transmitter can accept 4K50/4K60 4:4:4 (18G) HDMI 2.0 signals. The built-in down-
scaler ensures appropriate scaling to maximum HDBaseT bandwidth of 10.2G, whilst providing
compatibility with of the display unit. Three scale options are available as per below:
1. Down-Scale any 4K resolution to 1080p
2. Convert 4K60 4:4:4 signals to 4K60 4:2:0 (colour-space conversion)
3. Auto: Provides optimal resolution / colour-space option, based on cable length and
display capability.
See
4K Down-Scaling
in the
RS232 Control Commands
section.
Connecting to the IR Ports
The IR IN and IR OUT ports on the rear of the Transmitter/Receiver units may be used to send
IR remote control data between the two units. The following table details the wiring
connections for the IR input and output ports:
