Explanation
The response values are single Bytes except in the case of the [OUTPUT] which is always
a double Byte, eg. ‘12’.
List of RS-232 Commands
The underlined values mean the default settings.
Typical Application
RS-232 Commands
Below listed commands can be used to query or control the receiver. The commands can be
sent via the local RS-232 port or via the TPS line. Please check the serial port settings which
are xed in the device:
Baud rate: 9600; data bit: 8 bits; parity: none; stop bit: 1
Connect a cross-link serial cable between the receiver and a computer.
Protocol Description
The commands must be followed by Carriage return and Line feed (<CR><LF>).
The parameters can be queried (read) by the ’R’ letter in each case.
The parameters can be set by the ’S’ letter.
The commands are not case-sensitive.
The ● symbol means the space character in below examples.

Error Responses
When undened value is sent (e.g. S SOURCE 9) the response will be ERROR. Unknown
and insufcient commands are not processed, response is not sent.
The Handling of the Batteries
Use only standard batteries. Do not use new and used batteries together. This may cause a
battery to break or leak and may cause re, injury, or contamination (damage). When replacing
the batteries, insert them with right polarity. Otherwise, the battery may become damaged or it
may cause re, personal injury or damage due to leakage of the internal liquid. The batteries
(and rechargeable batteries) are not ordinary refuse and must be returned for recycling
purposes. The customer is responsible for returning the used or rechargeable batteries for
recycling. Be careful that children do not place the batteries in their mouths when removed
from the remote control. Place the battery in a location that children or infants cannot reach.
Correct Disposal of Batteries in this Product
This marking on the battery indicates that the batteries in this product should
not be disposed of with other household waste at the end of their working life.
Where marked, the chemical symbols Hg, Cd or Pb indicate that the battery
contains mercury, cadmium or lead above the reference levels in EC Directive
2006/66. If batteries are not properly disposed of, these substances can
cause harm to human health or the environment. To protect natural resources and to promote
material reuse, please separate batteries from other types of waste and recycle them through
your local, free battery return system.

Firmware Upgrade
To have the latest rmware running in your device, please do the followings:
1. Contact Lightware Support to get the latest rmware le.
2. Copy the rmware le to an USB ash drive. Make sure that the le system is FAT/FAT32
and the name of the rmware le is MSTFLASH_FILE_CH_521RX.bin.
3. Disconnect the power supply unit from the receiver.
4. Insert the pen drive into the USB service port of the receiver.
5. Press the Menu button and keep it pressed.
6. Connect the power supply to the receiver. The device is powered on, the upgrade is
started while the front panel Input LED lights in red; release the Menu button.
7. After cca. 30 seconds later the process is nished the front panel Input LED is blinking in
green/red and the Power LED also blinks.
8. Unplug the power supply remove the USB pen drive and reconnect the PSU again.
Software Control – Using Lightware Device Controller
The device can be controlled from a computer using the Lightware Device
Controller (LDC) software. The application is available at www.lightware.com

or a Mac OS X and connect to the device as follows.
Connecting via the RS-232 Port
1. Connect a computer to the RS-232 port of the receiver by a cross-link serial cable.
2. Launch the LDC software and select the Serial Devices tab.
3. Press the Query button of the given COM port, select the device and press the Connect
button.
Connecting via the TPS Line to an MX-FR Matrix Switcher (TPS Output Board)
1. Connect the receiver to an MX-FR matrix with TPS output port.
2. Connect the matrix to a LAN and connect a computer to the same LAN.
3. Start the LDC software and connect to the matrix listed at Ethernet Devices tab.
4. Open the Port properties panel of the given TPS output port and press the Open remote
device settings button at the bottom of the window.
The preferred resolution of the last attached sink will be the default when connected.
