Overview
The DC-LINK-CLR2 is a high-performance WHDI video transmission system which transmits uncompressed video and audio signals up to 300 m / 1,000 ft with no latency (< 0.001 s delay).
NOTE: The actual transmission ranges depend on setup, alignment and a variety of environmental influences. Also, the transmission power of the transmitter affects the range of the receiver. Therefore, the transmission range of the X.LINK-S1 receiver can be significantly more with a ULR1 transmitter than with a CLR2.
Due to the conscious decision not to implement DFS (Dynamic Frequency Selection) the device has a longer range, greater stability and better usability than comparable systems that DO use DFS.
The transmitter and receiver both have 3G-SDI and HDMI connectors (Plug & Play). When a video source is attached, the transmitter automatically selects the input (SDI is prioritized). The receiver’s 3G-SDI and HDMI outputs can be used simultaneously.

Encryption (for all MKII devices) In encryption mode, the transmitter sends an encoded signal that only linked receivers can read, making it easy to protect confidential content that is not meant for everyone’s eyes. To activate encryption mode, press and hold the MENU button on your device to enter the encryption menu. Use + or ­ to check either ON or OFF and confirm with MENU. The main menu will show either ENC or ENC to indicate whether encryption is on or off. To link your devices, set your transmitter and all the receivers to the same channel, then activate encryption on your transmitter. All receivers will follow into encryption mode automatically. Settings remain active after turning your devices off. This means that ENC can be prepared prior to shooting and will stay active unless you turn it off. A linked receiver does not HAVE to stay linked. To take a receiver out of the encrypted system, simply turn off ENC. Then you can easily access another (unencrypted) transmitter’s images by choosing the referring channel within seconds. To link back to the previous (encrypted) transmitter, turn ENC on again.
IMPORTANT: Switching back and forth between two encrypted systems is not possible. You cannot slip into an encrypted wireless system, if your receiver was not initially linked to the transmitter. If you want to add a new receiver to an encrypted system, you need to link the whole system again.
Reducing Transmitter Power On ULR1 and LR2 transmitters it is possible to reduce the transmit power, for example to avoid interferences due to too short distances. Use MENU to navigate to the transmit power display (superscript number next to the channel display). Adjust the transmit power with + and – and confirm with MENU. The number shows the transmit power in %. The lowest possible transmit power is 10 %.

Troubleshooting

No video output
Inadequate video quality

Possible Cause
Lack of power
Antennas
Video connection cable Frequency selection Unsupported video format Connections
Range is too great or signal is obstructed

Possible Solution
Check power supplies of transmitter and receiver and ensure that all cables are connected properly and that there is sufficient power.
Ensure antennas are not damaged and are firmly connected. Please use the DC- Scan to check.
Examine the transmitter’s “Video” LED display. If the LED is dark, check the HDMI or SDI connection cable.
Ensure that the transmitter and receiver are set to the same channel.
Make sure you using a supported video format.
Ensure that all SDI or HDMI cables are firmly connected.
Check how many “RSSI” LEDs are lit on the receiver. For decent quality, at least 2-3 LEDS should be lit. If only one is lit, the signal is weak and the distance between transmitter and receiver should be reduced. Alternatively, obstacles between the devices should be removed or another channel selected.
