Transceiver responsibilities and malfunctions
Material in this article pertains to planned features for Companion 8.5.

Modern robots are highly dependent on a wide range of electromagnetic communications. A typical NS controller has five transceivers:

transceiverbandresponsibilities
X-series radio modem (XSRM)VHFXanadu Package Service (Companion 8.0)
Xanadu Network Management Service (Companion 8.4)
Navigation Routing Service (Companion 8.4)
Nanite Systems Weather Service (ATOS)
sub-optical data link (SODL)EHF/FIRLight Bus (local)
Exhibition 4 Teletype Terminal Access (Companion 8.3)
ORIX Identification (Companion 8.3)
(Spectrum+1) Charging (Companion 8.3)

Icon Particle Sink Priority
Private Command Bus
Identification Friend or Foe (ATOS)
LiveNet (discontinued)

NSMIL Charger Data Link


Direct damage to the main controller can affect the functioning of any of these radios, which may result in impairment or total loss of function of the associated services. Some repairs are within the scope of nanite-mediated repair, such as that offered by a repair tool or ARC repair station, but not all of them. Other damage, such as a cracked crystal, may require the attention of a trained technician using a VectorLogix Diagnostics bed. Corresponding error codes are as follows:
  • RT-0201: SODL damaged. Foreign devices may not be able to authenticate. Repairable. The unit will not be able to fully connect to the diagnostics bed until this issue is resolved.
  • RT-0205: SODL offline. Bed maintenance required. The unit will not be able to fully connect to the diagnostics bed until this issue is resolved.
  • RT-0206: SODL not responding. Repairable. The unit will not be able to fully connect to the diagnostics bed until this issue is resolved.
  • RT-0305: CR damaged. Public command bus offline. Repairable. The unit will not be recognized by ARCs due to IFF failure. ORIX authentication (via SODL) or NSMIL authentication (via BSMT) must be used to connect to the diagnostics bed.
  • RT-0306: CR damaged. Private command bus offline. Repairable.
  • RT-0307: CR offline. Bed maintenance required. The unit will not be recognized by ARCs or the diagnostics bed using the public bus ping or with IFF, so either the SODL or BSMT transceivers must be used to authenticate with the bed. However, a repair tool can be used to resolve this problem.
  • RT-0602: BSMT offline. Bed maintenance required. The unit will not be able to use chargers until this issue is resolved, and may not be recognized by ARCs.
  • RT-0603: BSMT damaged. Repairable. The unit will not be able to use chargers until this issue is resolved, and may not be recognized by ARCs.
  • RT-0608: BSMT not responding. Repairable. The unit will not be able to use charger until this issue is resolved, and may not be recognized by ARCs.
  • RT-0802: CHR damaged. Local (/1) command access not available. Bed maintenance required.
  • RT-0805: CHR not responding. Local (/1) command access not available. Repairable.
  • RT-0809: CHR offline. Local (/1) command access not available. Repairable.
  • RT-0901: XSRM damaged; software installation, domain synchronization, and navigation routing may not function properly. Repairable.
  • RT-0903: XSRM not responding. Repairable.
  • RT-0907: XSRM failure. Bed maintenance required.
Other RT error codes may require a return merchandise authorization (RMA) for replacement. Certain combinations of error codes may render the unit unsalvageable.
