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.
