====== RJ45-Board ======

===== Description =====

The RJ45-Board is very simple, it comes with 4 self-resetting polyfuses, 4 RJ45-female connectors in one shielded housing and a 12-pin connector. Therefore the probability for mistakes is very low. Verify the correct orientation of the ribbon cable between Adapterboard and RJ45-Board.

RJ45-Board with Test Points

===== Test Points RJ45-Board (connected via 12-pin ribbon cable to Adapterboard with Display and Cubieboard) =====

^  Test Point  ^ Description  ^  Nominal Value   ^  Measured   ^  Remarks  ^ 
|  RB1    |  12 V IGC T1   |  12 V          |              |If not present, check orientation of 12-pin connector |
|  RB2    |  12 V IGC T2   |  12 V          |              |If not present, check orientation of 12-pin connector |
|  RB3    |  12 V IGC T3   |  12 V          |              |If not present, check orientation of 12-pin connector |
|  RB4    |  12 V IGC DBG  |  12 V       |              |Debug-Terminal, only required for Developers, if you want to know what is inside, check this out: [[serial_console_boot_log]]. The signal comes from CT1 and CT2, goes via AT8, is level shifted and ends near to RB4  |

===== Connectivity to external NMEA-equipment (Flarm, Logger, ...) =====

The Openvario has rich choices to connect external equipment with RJ-45 connectors in IGC-pin layout. Nearly all loggers, Flarms, Varios from the world of gliding come with the dedicated IGC-Layout, which has become a "Quasi-Standard" within the years. 

Caution: Do  **not** connect the Nano-Logger directly because of incompatible Pin-Assignment! The Nano-Logger needs a specialized cable to be connected!
Before connecting any external NMEA-device via a RJ45-patch cable, be sure about the correct Pin-Assignment. 

===== RJ45-IGC Pin Assignment =====

===== Settings in XCSoar =====

  * required Information: Baud Rate, Device Driver Name, Port Name
  * xcsoar Device Manager (Config -> Device)
  * Monitor the NMEA output of your Device, if output is nonsense, try another Baudrate
