Hardware Reference Manual – DXLink™ Twisted Pair Transmitters/Receiver

Technical Support

If this manual has not satisfactorily answered your questions regarding the DXLink Transmitters and Receivers or they are not

operating as expected, please contact your AMX representative or technical support. Have the serial numbers for the modules

ready. If the modules are connected to a switcher, locate the serial number for the switcher too.* We recommend recording the

serial numbers in an easily accessible location.
