Power transfer protocols
For historical, practical, and reliability reasons, SXD compatibles support a large number of methods for charging and power exchange. The major interfaces are as follows:

modulemethodtransceiver band(s)physical component
coilinterface chargingBSMT, SODLprimary AC transformer coils (50 Hz or 60 Hz)
Heavy-gauge copper coils engineered for high-performance magnetic induction as part of the DAX/2 design requirements. This replaced the original SXD 1.0 charging hardware; all surviving models were retrofitted. For information on the protocols used, see the source code of the _coil module in the main controller's system memory. Devices that feed power to the system via interface charging include:
  • NSFRG Induction Chargers
  • SXD Charging Station (discontinued)
  • Destruir Technologies Wireless Charging Station
  • Autonomy Control Systems CP series
  • UMD charging pads
  • Qetesh UMD charging pads
  • Refactor Robotics Aurora chargers (1.0 and earlier)
  • CEE, NEMA, and FSD power outlets
  • NSBSD Asset Recovery Chamber (ARC) 47-2704 series (discontinued)
  • NSBSD Asset Recovery Center (ARC) 47-9000 series

Light-gauge coils intended to allow the unit to recover energy from ambient magnetic fields. The efficiency of environmental induction varies between chassis designs; this is called induction efficiency and is a CSU parameter. There are a number of devices designed specifically to charge robots using this method, including:
  • NSCP Demo Stand
  • NSCP Collector's Display Case
  • All NS Wireless Mesh Network Charging Node (WCN) products, unless otherwise specified
  • Third-party chargers derived from the "SitAnywhere Charger" DDK
  • NS Pulse Charger and Pulse Beacon products
  • zap-based unit-to-unit wireless power transfer

Environmental induction from registered ("active") devices attached to the light bus will continue to work even if the unit's induction efficiency is impaired. Devices utilizing this method include:
  • NSCP Nanoconnectivity Interface (dynamo hand crank)
  • Tez Yohkoh's Wind Turbine and Solar Prism chargers

bondsconnected loadsn/adirect connection only
Although intended to allow the unit to act as a battery or power source for other hardware, the light bus "device load" protocol can be reversed, restoring power to the unit. Devices utilizing this method include:
  • NSBSD MESH-2100 series shields (draw only)
  • NSBSD Shinsakuto (draw only)
  • NS VectorLogix diagnostics bed (charge only)
The ATOS weapon reload protocol is similar to this method, but it is mediated over short-range wireless link using the CR radios.

bondsdirect accessn/adirect connection only
Certain devices directly provide additional charging interfaces through various idiosyncratic methods. These include:
  • NS Arachne X8 diagnostics bed

battery protocol emulationn/adirect connection only
The MISTIX Battery Charger for NS directly connects to battery devices that have been placed into it.
