4.6.4. Relay Interface
HDMI-TPS-RX110AY receiver contains two relay modules which can be accessed by a 4-pole Phoenix
connector.TherelayscanbecontrolledbyLightwareprotocolcommands(LW3)andEventmanageractions
can be assigned to the port.
ATTENTION!
The device built with normally open (N.O.) contact relays which means when the unit is not
powered (DC plug is disconnected), the relays will open.
INFO:
The default state of each relay ports is open.
Application of Relays - Example
The Concept
Ceiling lamp is turned off by Relay 1 and projection screen is rolled down by Relay 2 when signal received
from the transmitter over TPS input line.
Settings of the Receiver
▪
Relay 1:createaneventinEventmanager:whensignalispresentonInput1(I1)thensetRelay1to
be open. Also create another event when signal is not present on Input 1 (I1) then set Relay 1 to be
closed.
▪
Relay 2:createaneventinEventmanagerwhensignalispresentonInput1(I1)thensetRelay2to
be closed. Also create another event when signal is not present on Input 1 (I1) then set Relay 2 to be
open.

4.6.5. Consuming Electronic Control (CEC) Interface
DIFFERENCE:
This feature is available only in HDMI-TPS-RX110AY-Plus model.
ConsumerElectronicControl(CEC)isabi-directionalcommunication,definedintheHDMIstandard.This
featureisforremotecontrolofthesourceandsinkdevicesintheA/Vsystem.
HDMI-TPS-RX110AY-Plus model is able to send and receive CEC commands, from the input ports towards
the source, and from output port towards the sink. For more information about sending CEC messages, see
Sending CEC Commands
section.
CEC has a dedicated pin in the HDMI connector. DVI connector does not contain this pin, so the CEC
transmissionbrakeswhenHDMI-DVIconnectororadapterisinthesignalroute.
CEC Application Example

to wake up.
Createaneventintheeventmanager:
▪
Set as a condition, that the signal is present on the output (O1),
▪
Set as an action then send a CEC command 'Image view on' O1 output port.

ATTENTION!
The CEC command sending over TPS interface is working only with CEC-transparent
TPS transmitters. For the details please download our Using CEC in Lightware Devices document on
