Astronics Max-Viz 1500 - Interface Connections

Astronics Max-Viz Max-Viz 1500 3091-00019 Rev M
3.1. Interface Connections
3.1.1. Interconnect Pin-outs between Sensor LRU and Power Supply LRU
The cable harness between the Sensor and the Power Supply can be fabricated from
standard 22 AWG aircraft wire (e.g., M27500 twisted shielded pair). A typical
installation length is 14 to 24 inches depending on the actual locations of the two LRUs.
Notes:
 Maximum recommended LRU separation is 100 feet.
 If the harness between the Sensor and Power Supply is longer than 12 feet, a
larger AWG size is recommended (video coax excluded).
 Pin numbers are the same at each connector between the Sensor and Power
Supply.
 An overall metal cable shield tied to both ends into the connector backshells is
recommended.
 TP = Twisted Pair.
 If additional bulkhead connectors are connected in-line, each contact must be
rated for 5 Amps or more.
 Under no circumstance may signals from multiple pins be spliced and carried in a
single wire.
