Troubleshooting and maintenance
 No image on display
 Ensure that the display device has been set to the correct input.
 Ensure that the HDMI cables used for both the source/switch and the
receiver/display are properly connected and are working. Test the HDMI
cables directly from a source to display and ensure their operation.
 Ensure that the Cat5e/Cat6 cable has not been damaged and that it has been
terminated correctly with T568B on both ends. A temporary length of
Cat5e/Cat6 can be used for testing to ensure that the devices are all
compatible and working properly.
 Ensure proper grounding of the power supply.
 Known issues with HDMI 1.2 source devices
 Certain cable television STBs are known to have issues with HDBaseT
transmission. This is due to their older compatibility (HDMI 1.2). Contact
Clare customer support for a solution to these issues.
 Color loss or poor picture quality
 Ensure that the HDMI cables used for both the source/switch and the
receiver/display are properly connected and are working. Test the HDMI
cables directly from a source to display and ensure their operation.
 Ensure proper grounding of the power supply.
 If the static becomes stronger or picture quality worsens when connecting the
video connectors, this may be due to improper grounding. Check the
grounding and make sure all components are properly grounded to a
common ground. Improper grounding may damage the receiver.
 IR signal problems

When using a control system such as Clare Controls, Crestron, or URC, the
3.5 mm female mono to 3.5 mm male stereo adapter cable (included) must
be used. Connect the female mono end to the control system. Connect the
male stereo end to the CM-BT10-TX70.
 Unable to control the matrix via RS232
 Ensure that a null modem cable has not been used.
 Ensure that the control system has assigned the commands to the correct
COM port.
 Verify that the commands and protocols used are correct. All commands are
case sensitive and require precise entry.
