6. APPLICATION & INSTALLATION
6.1 Typical Application
DCP-SRX is normally used with DCP-MTX 4K HDBaseT Daisy-Chain Presentation
Switcher and supports cascade connection of multiple DCP-SRXs and DCP devices.
To install multiple DCP-MTXs and DCP-SRXs, simply connecting HDBT OUT of DCP-
MTX/DCP-SRX to HDBT IN of next DCP-MTX/DCP-SRX, you will get a Chain Mode
connection. By connecting the last DCP device back to the first through HDBT, you will
get a Ring Mode system. (see application example below).

6.2 Installation & Connection
To create a Chain- or Ring-type connection of multiple DCP-MTXs, DCP-SRXs, sources
and displays, please refer to the instructions below and the “SYSTEM WIRING” chart:
1. Connect DCP-MTXs and DCP-SRXs through HDBT:
1) Connect HDBT OUT of the first DCP-MTX to HDBT IN of the next (e.g. DCP-
MTX 1 to DCP-MTX 2);
2) Connect the rest DCP-MTXs through HDBT likewise.
3) Connect HDBT OUT of the first DCP-SRX to HDBT IN of the next (e.g. DCP-
SRX 1 to DCP-SRX 2);
4) Connect the rest DCP-SRXs through HDBT likewise.
5) Connect HDBT OUT of the last DCP-MTX to HDBT IN of the first DCP-SRX

11
USER MANUAL
DCP-SRX
(e.g. DCP-MTX N to DCP-SRX 1).
6) If Ring Mode connection is required, connect HDBT OUT of the last DCP-SRX
to HDBT IN of the first DCP-MTX (e.g. DCP-SRX N to DCP-MTX 1).
2. Set up IP Sequencing for all the DCP-MTXs and DCP-SRXs.
• Option A: Using the MYTURN button of the first DCP-MTX (e.g. DCP-MTX 1)
a) Long press the MYTURN button of DCP-MTX 1 for 10 seconds;
b) The input LEDs (HDMI IN, DP IN and VGA IN) will flash twice, then
DCP-MTX 1 will start IP sequencing automatically and the rest DCP-
MTXs and DCP-SRXs will get its individual IP address according to
their sequence in the connection loop (for instance, if DCP-MTX 1 gets
192.168.1.121 (Default IP address of DCP-MTXs), then DCP-MTX 2 will
get 192.168.1.122.)
• Option B: Using Start Sequence button on Web UI.
a) Connect your PC to ETHERNET port of the first DCP-MTX (e.g. DCP-MTX
1).
b) Login Web UI through a web browser (Default IP address of DCP-MTXs
is192.168.1.121).
c) Go to Configuration > Device > Daisy-chain Sequence. Select Daisy-chain
quantity and click “Start Sequence” to allocate IP addressing to each DCP
device.
3. Connect source and display devices to DCP-MTXs.
4. Connect an HDMI display device to HDMI OUT of each DCP-SRX. If audio output is
required, connect an audio system to AUDIO OUT of DCP-SRX.
NOTE:
• Default IP address of DCP-SRX is 192.168.1.122, DCP-MTX is 192.168.121.
• The PC used to login Web UI of DCP should be set in the same network segment
as DCP devices, e.g. 192.168.1.x.
• To avoid IP addressing conflicts, please repeat Step 2 if any DCP-MTX or DCP-SRX
is reset, removed from and added to the connection.
• To make CEC control effective, please use CEC-enabled display devices.
• Quality CAT cables, e.g. Cat6, AWG23 or S/FTP cable, are highly recommended.

7. CEC & RS232 AUTO CONTROL
DCP-SRX is embedded with a CEC controller and a RS232 controller. When CEC /
RS232 Auto Control is switched on, DCP-SRX will detect the signal status and send
CEC / RS232 command to power on or off the display connected. CEC / RS232
Auto Control of DCP-SRX can be configured through Web UI or Telnet. For more
information, please refer to “8.1 WEB UI” and “8.2 TELNET“.
When CEC / RS232 Auto Control is enabled,
• DCP-SRX will automatically detect the status of signal from HDBaseT IN.
• DCP-SRX will power on the display (see flow chart below):
1) If active input signal is present, DCP-SRX will send a CEC/RS232 command to
power on the display connected to HDMI OUT/RS232 port immediately.
