 NO field-terminated plugs

o all plugs and fly-leads must be factory pre-terminated, moulded type

 instead field-terminated fixture cabling into punch-down blocks in wall-plates and/or patch-

panel within AV rack are allowed

 HDbaseT Standard requires maximum total end-to-end length of 100 m including patch-leads

i.e.: X + Y + Z < 100 m and

Z < 100 m – X – Y

as set out in diagram below

 a maximum of two patch-leads (two joins), as specified by HDbaseT Standard and Valens, i.e.

one (max length, Y, 5 m) from wall-plate to remote DXLink device, plus one (max length, X, 5 m)

from head-end switch/device to wall-plate/patch-panel at/in AV rack:

 no double-patching:

double-jumpering (e.g. via an intermediate Krone frame within a Comms room) is not permitted;

instead the cable must be wired direct from wall-plate to patch-panel in AV rack, as shown

above

 no IDFs:

HDbaseT must not be passive-patched at a Comms room distribution frame for interconnection

between remote devices

(apart from the risk of the doubled end-to-end distance exceeding 100 m limit there-and-back,

the additional intermediate patching violates the HDbaseT Standard as set out above)

 use of shielded:

AMX recommends shielded, i.e. FUTP cable, particularly in challenging power interference

environments

 where shielded is employed, shield must be properly grounded:

o Installer must submit proposed grounding strategy for approval by DeS AV and

Networks Unit Leader prior to commencement of works, and

o Installer must indicate whether proposed grounding strategy is intended to provide a

low frequency (safety) ground and/or high frequency (signal interference) protection.
