transmitter
The following ways are available for controlling the devices:
▪ The System controller can communicate with the Transmitter by LW2/LW3 protocol commands sent to
the local IP:port address.
The System controller can communicate directly with the Projector or an Extender via their IP:port address.
▪
▪ The System controller can communicate directly with the RS-232 Relay box connected to the Transmitter.
In this case, Command Injection mode has to be enabled on the local RS-232 port.
The Transmitter can send a command (e.g. as an action by the Event Manager) to the IP:port address
▪
of the Projector or the Receiver by using LW3 protocol methods.
Command Sending
▪ You can send LW3 protocol commands to the 192.168.0.100:6107 port to control the transmitter.
▪ You can send LW2 protocol commands to the 192.168.0.100:10001 port to control the transmitter.
You can send commands to the 192.168.0.100:8001 port to control the projector. This port number
▪
means the RS-232 interface of the optical output port (O1).
INFO: Above values are examples and based on factory default settings.
INFO: Only SW4-OPT-TX240RAK model has Ethernet LAN port.

transmitter
The Concept
You can control the Projector over the extenders with the System controller. The controller is connected to
the local RS-232 port of the Transmitter which transmits the signal toward the Receiver over the fiber optical
line. The Projector is connected to the local RS-232 port of the Receiver. The serial connection is bidirectional
which means the controller gets back the responses of the projector.
In this case the RS-232 port of the transmitter and receiver either has to be set to Pass-through mode.

3.11.2. GPIO Interface
INFO: Only SW4-OPT-TX240RAK model has GPIO interface.
The GPIO (General Purpose Input/Output) port is a multifunctional input/output interface to control the SW4-
OPT-TX240RAK transmitter or third-party devices and peripherals. You can establish connection between
the controller/controllable device and the transmitter by the 8-pole Phoenix connector. The deriction of the
seven pin is configurable independently based on the purpose of the application.
Projector
GPIO Options - Example
Ceiling lamp
PC
The Concept
Ceiling lamp is turned off by Relay 1 and projection screen is rolled down by Relay 2 when signal received
from the PC over the DVI-D input. Both relays are controlled by the GPIO port.
Settings of the Transmitter
▪ For Relay 1: create an event in Event Manager: when signal is present on Input 1 (I1) then set GPIO pins
to low level for Relay 1 opening. Also create another event when signal is not present on Input 1 (I1)
then set GPIO pins to high level for Relay 1 closing.
▪ For Relay 2: create an event in Event Manager when signal is present on Input 1 (I1) then set GPIO pins
to high level for Relay 2 closing. Also create another event when signal is not present on Input 1 (I1)
then set GPIO pins to low level for Relay 2 opening.
Projector When the PC starts to play the video presentation, the signal is received over the DVI-D input so GPIO pins
send signal to Relay 1 to open which results turning off the lights. Furthermore GPIO pins also send signal
to Relay 2 to close and the projection screen is rolled down. When the presentation is ended, signal ceases
on the DVI-D input, so GPIO pins send signal to Relay 1 to close which results turning on the lights and sends
signal to Relay 2 to open so projection screen returns to its enclosure.
ATTENTION! Please always check the electrical parameters of the devices what you want to control. The
maximum current of one GPIO pin is 30 mA, the maximum total current for the seven pins is 180 mA.
