3.2.3 CONNECTIONS ON THE DUAL DAISYCHAINABLE RECEIVER
The dual daisychainable receiver is used when the same signal is distributed to
multiple display devices on a single cable in a daisychain or loop-through
fashion. CAT5 Cable lengths must not exceed 600 ft between units.

fashion. CAT5 Cable lengths must not exceed 600 ft between units.
Setup and cabling are the same as the single-port receiver, but the dual
daisychainable model has an additional RJ-45 connector for linking to another
dual daisychainable receiver or single-port receiver.

4. Troubleshooting
4.1. Common Problems
In most cases, nearly every issue with the Multi DVI System can be resolved by
checking the Fiber optic or CAT5 cable and making sure that it’s properly
terminated and in the case of CAT5 cable, pinned to the TIA/EIA 568B wiring
specification. However, there may be other problems that cause the system to not
perform as it’s designed. Below are solutions to the most common installation
errors.
Problem: No video signal at the transmitter local port or at the receiver.
Solution: • Check that both units are powered.
• Make sure the cable is terminated correctly.
• Is the display device powered on and functioning?
• Power on units in sequence (display, receiver, transmitter, video
source).
• Display may not be correctly identified by source device. See
Appendix E for DDC communication issues.
Problem: Video signal is poor.
Solution: • See Appendix C for changing compression mode.
• Check all cable connections.
• The video signal’s refresh rate may be set too high. Reset to a
lower refresh rate in your monitor-configuration menu.
• In 1080P mode, the PC graphics card needs to be set to
reduced clock rate mode. Contact the graphics card
manufacturer.
