2.10 Serial Interfaces
The AT8050 uses serial interfaces to manage the CPU. Since no video interface is provided on board, the only
way to get visual information on the board is the serial console. Serial ports are provided on the faceplate
and on the RTM faceplate for asynchronous serial communications. They are 16C550 high-speed UART
compatible and support 16-byte FIFO buffers for transfer rates from 9,6Kbps to 115,2Kbps.

2.11 AMC Mezzanine
The AMC slot supports AMC.1 (PCIe), AMC.2 (Gigabit Ethernet) and AMC.3 (SAS/SATA) in addition to the
AMC.0 base specification. The AMC is hot swappable according to PICMG 3.0 Rev. 2.0 and supports mid-size
AMC units.
One AMC site is available. Characteristics of the AMC are as follow:
•Type B+
•Support mid-size single width mechanical format

Note:
Standard product uses a RJ-45 8 pins connector. RI (ring indicator) and DCD (data carrier detect)
signals are not available.
The pinout is a custom one, not the same as RS-232D TIA/EIA-561.
Signal Path:
COM1 is routed to a RJ45 on the frontplate or to the IPMC for SOL.
COM2 is routed to the RTM or the AMC serial interface port is routed directly to the RTM.
