IMPORTANT NOTICE!
We highly recommend using only Kramer UNIKAT cables with these products. If using 3rd party shielded CAT-6A cables, both ends of the
shield must be soldered to the connectors for the products to function properly. Do not use any jumpers, unshielded wall plates or midspan cable connections. These extenders are not compatible with HDBaseT technologies. Prior to signal extension, ensure that the
extension line cable is lying straight and not coiled.
Step 2: Get to know your VM-4DKT
