Connecting multiple senders – Daisy-chain
Daisy-chaining Audio and Video
To extend video to more than eight remote displays, additional senders can be
daisy-chained together using the HDMI IN and HDMI OUT connectors.
The ECHO-4S and ECHO-8S support daisy-chaining of up to eight senders;
totaling up to 64 possible remote displays.
To daisy-chain the HDMI source, use quality
HDMI cables to connect HDMI OUT of the
first box to HDMI IN of the second.
Hall Research carries a line of SnugFit™
HDMI cables designed for HDMI 2.0 and
featuring locking tabs to more securely affix
Model CHD-SF*
the HDMI cable in the connectors.
Daisy-chaining RS-232 (ECHO-4S and ECHO-8S)
By default, RS-232 sends all characters received by the 1 ECHO-x RS-232 input
st
to all RS-232 outputs at each receiver and RS-232 Loop Output.
If certain RS-232 outputs in the daisy-chain require unique commands, then
each sender must be assigned a unique device ID (from 1 to 8).
This ensures that every HDBaseT Output has a unique address for connecting
and routing serial commands. See Section 5 below for information on setting
Device IDs.
To daisy-chain the RS-232; connect the RS-232 Loop of the first Sender to the
RS-232 In of the second, and so on.
RX Loop connects to TX In, TX Loop connects to RX In, and GND connects to GND
