-We are engaging with Arkidelo to design and fabricate low-pressure encapsulation mould for the D-SUB 25 connector, to provide appropriate environmental sealing of the cable headfrom which the power input connector, battery connector and (optional) external USB charge ports will emerge.  This will also need to include provision for the thumb-tighten screw-ins for the connector.  The purchase order for Arkidelo to begin work is due to be raised on 03MAR17and will take approximately 7 weeks before we receive the first parts.+This cable is IP65 D-SUB 25 female to 3-pin and 4-pin IP67 cable, designed to connect the Mesh Extender to each of: 
 +   * solar panel OR vehicular 12v/24v supply 
 +   * 2-cell LiFePO4 or 6v sealed lead acid battery 
 +It also contains an integrated I2C EEPROM that tells the Mesh Extender which radio frequency and transmit power it is allowed to usealong with other configuration data.
  
-For the power input / USB charge port connector, we are currently intending to use http://www.banggood.com/10Pairs-DC-MaleFemale-4PIN-24AWG-Waterproof-IP65-PVC-LED-Connectors-p-1073265.html?rmmds=search  (AU$1.38 each, for IP65-rated 4-pin 1A connectors)+[[content:meshextender:me2.0_standard_power_cable_pinout|Pinout for standard power cable]]
