¶ Introduction
The LDT-RX1 is a wireless receiver unit that is designed to receive data from the wireless LDT range. A powerful receiver module that works at sub Wi-Fi frequency which will cut through the wireless noise of a busy set to deliver excellent results when paired with an LDT wireless transmitter product.
The LDT-TX1 is a wireless transmitter that connects directly to smart lenses through the 4pin port. It streams lens data using a sub Wi-Fi frequency to the LDT-RX1, ensuring exceptional performance even and avoiding the interference on a busy set. The streamed data can be utilised within Unreal Engine via the DCS Plugin, enabling precise, real-time interaction with the physical lens.
Please note that one LDT-RX1 is required for each LDT wireless transmitter.

| ETH | RJ45 | Ethernet connection port | Ethernet cable |
¶ Cable Types and Codes
All DCS cables are categorized using a code and a bend relief color for each of the cable types. The lemo connector type can be straight (S), right angle (R), or anglissimo (O). Custom cables can be made upon request.
| Code | Bend Relief Color | Type | Description |
|---|---|---|---|
| PWRE | White | 2 pin Lemo to international socket | Used to power the LDT-RX1 or LDT-TX1 from a mains supply |
| PWRG | White | 3-pin Lemo to 2-pin Lemo | Used to power the LDT-TX1 from a camera |
| PWRH | White | DTap to 2-pin Lemo | Used to power the LDT-TX1 from a battery or power plate |
| Not DCS specific cable | N/A | Ethernet to ethernet | Used to send data to the media player machine. Use any compatible RJ45 ethernet cable |
¶ Status Lights
The LDT-RX1/LDT-TX1 has 3 status lights on the unit and 2 status light on the ethernet port to provide an overview of how the unit is working.
¶ LED below PWR:
- Green: External power in
- Red: Power failure
¶ LED in between PWR and ETH:
- Heartbeat light means there is connection between the OEM and the LDT-RX1 motherboard
¶ LED on the ETH port :
- Green: Solid - when connected. Blinking - data is being sent.
- Yellow: Solid - PoE is connected and valid
¶ LED below antenna:
- Green: Connection to LDT Transmitter/Receiver
- Red: No connection
¶ Reset Button
The recessed reset button is to be used to manually reset all the settings of the LDT-RX1 and LDT-TX1.
The reset will occur after the button has been pressed for 2 seconds.
The unit will reboot shortly after this. The status LED/heartbeat will turn orange when the reset is pressed successfully.
Please note that all settings will revert to factory default and any personalised settings will be lost.
¶ Mounting
The LDT-RX1 and LDT-TX1 casings have 3 points to mount the unit to a 3/8" stand.
¶ Antenna
The LDT-RX1 and LDT-TX1 are both compatible with any SMA male antenna which works between 2200-2500 mhz freq.
¶ Frequency information
The LDT-RX1 and LDT-TX1 work at any frequency between 2200mhz and 2500mhz. This is configurable in the settings.
Ensure the LDT-RX1 is set to the same frequency as the LDT-V2 or LDT-TX1.
Please note that the DCS wireless system only works between DCS branded products and requires an LDT transmitter and receiver. For instance an LDT transmitting device (such as the LDT-V2/LDT-TX1) cannot be connected to a 3rd party router or other receiver and must be paired with a LDT reciever (such as the LDT-RX1).
If you are experiencing any level of interference with the wireless settings then fine tuning the settings of the LDT-RX1 and other wireless device will provide a more robust connection.
If any wireless settings are changed on the LDT-RX1 then please ensure that the same settings are set-up on the corresponding LDT transmitting device. LDT-V2 settings can be found here.
¶ Connection Information
Regarding issues with connecting the LDT-V2/LDT-RX1/LDT-TX1 to network equipment:
The DCS devices auto negotiate on Ethernet upto a rate of 100Mbps. The network equipment must be able to negotiate down to this rate. Equipment limited to 10G/1Gbps may require additional interfacing.
¶ Rigging the LDT-RX1
¶ Setting up the LDT-RX1
- Power the LDT-TX1 by connecting the PWR port either with the:
- PWRE international power block to a wall socket,
- Ethernet cable to a POE ethernet port.
The coloured light next to the LDT-RX1's antenna port means:
- Red means no connection
- Green means connected to another LDT unit successfully
¶ Rigging the LDT-TX1
-
Power the LDT-TX1 by connecting the PWR port either with the:
- PWRE international power block to a wall socket,
- PWRG cable to 2-pin power source,
- PWRH cable to Dtap power source,
- Ethernet cable to a POE ethernet port.
-
To access lens data from a compatible smart lens, use the SLP cable.
If enabled in the LDT-TX1 menu, the unit can power the lens itself, without the need for a powered mount on the camera.
The SLP cable should only be used on the LDT-TX1 and not any other unit.
¶ Settings
The LDT-RX1 and LDT-TX1 settings are controlled by a built in web interface.
Network settings selected on the LDT-V2 will not be used if connected to the LDT-RX1. The LDT-RX1 settings take priority and will be utilised.
¶ Accessing the LDT-RX1/LDT-TX1 Settings
- Connect to a computer using an ethernet cable connected to the ETH port and the corresponding port of the computer,
- Power the LDT-RX1 using the PWRE cable,
- Change the IP address of the computer to 192.168.1.XXX,
- On a web browser type in 192.168.1.100.
This will connect you to the web browser where all settings can be adjusted.
