A Lemo-0 connector, optionally used for the reception of an input
synchronization trigger pulse, usually from CERN's timing board
An EEPROM chip, loaded with IPMI FRU information (during PTS
testing) so as to comply with the FMC standard.
A 1-wire thermometer-unique-id-chip.
The schematics of the board, drawn in Altium, are available at CERN's
EDMS. As the following table
shows, three versions of the board have been designed.
A list of issues that were being identified and led to the development
of a new version is available in the issues

Different board executions exist depending on the WorldFIP communication
speed: 31.25kbps, 1Mbps, 2.5Mbps, and 5Mbps; a set of ten components
differentiates the board executions.
31.25k, 1M, 2.5M, 5M (different executions of hardware) Note that the 5M version is supported by the hw but is has not been tested and is not supported by the current gw/sw/lib
External sync. input
Optional sync of the WorldFIP start of macrocycle; LEMO 0 connector; TTL; Software selectable 50 Ohms termination
Front panel LEDs
FMC TX ACT: at the end of a macrocycle there has been no transmission failure FMC TX ERR: at the end of a macrocycle transmission errors have been detected FMC RX ACT: at the end of a macrocycle there has been no reception failure FMC RX ERR: at the end of a macrocycle reception errors have been detected FMC SYNC ACT: application expects sync pulse and it is receiving it successfully FMC SYNC ERR: application expects sync pulse which it is not arriving SPEC GREEN: blinking using the 100 MHz clock SPEC RED: PCIe reset
Four through hole test points (TP) next to the FMC connector: TP1: connected to FielDrive RXD TP2: connected to FielDrive TXD TP3: connected to Mock Turtle led&dbg reg bit 8 TP4: connected to Mock Turtle led&dbg reg bit 9
