3.1.3. Interface Connectors
The connectors required to fabricate a harness between the Sensor and the Power
Supply (each end terminated) are the same at each end and are:
 Connectors, qty 2, P/N D38999/26WC35SN (Max-Viz p/n 501500001) with
 Back shells, qty 2, P/N M85049/1913W04 (Max-Viz p/n 501000017) or Glenair
380HS001M1310H3 (Max-Viz p/n 501000034) or equivalent.
The connector required to fabricate a harness from a terminated end at the Power
Supply to the aircraft is:
 Connector, qty 1, P/N N D38999/26WB35SN (Max-Viz p/n 501500042) with
 Back shells, qty 1, P/N M85049/1911W03 (Max-Viz p/n 501000016) or Glenair
380HS001M1104A3 (Max-Viz p/n 501000035) or equivalent.
If either of the harnesses will run through a bulkhead, ensure that the connectors have
the appropriate number of pins (i.e. 22 or 13) and no wires are spliced together.
3.1.4.
Interconnection Losses
The maximum video coaxial cable loss from the Power Supply to the display should not
exceed 1dB. (Note: this is a generic figure to cover all AES types and equipment
configurations. If this cannot easily be achieved in any particular installation, then Max-
Viz, Inc. should be contacted to determine whether a more relaxed insertion loss can be
considered without decreasing system performance or raising certification issues).
There should be no cable loss limitations for RG-179 if less than 100 feet.
If multiple displays are to be connected, the video signal from the Max-Viz 1500 should
go directly to a multiple output amplified video buffer with as short of a run as feasible
prior to going to the displays in order to avoid signal termination losses
It is highly recommended to avoid routing the video coax in close proximity to electrical
noise sources such as motors, generators, transmitters, etc. Do not lace the video coax
cable together (in parallel) with high current conductors, particularly AC power type
wires such as 115 Vac 400 Hz or 60Hz.
3.1.5. Electrical Bonding Recommendation
If the Sensor or Power Supply units are not bonded electrically via their mounting holes
directly to a metal aircraft structure, then electrically bond them to the metal aircraft
structure with a heavy bonding wire (or grounding braid) from an unused mounting
hole.
