UART Interfaces
The F600 provides up to four UART interfaces that are controlled using USB ports
from the CPU board. Physical interfaces from RS232 to RS485—isolated or not—
are implemented using SA-Adapters via 10-pin on-board connectors. Data rates up
to 1 Mbit/s are possible.
By standard, F600 comes with two on-board 10-pin connectors for direct
connection of SA-Adapters at the front panel.
Another two UARTs can be implemented as an option, also through two on-board
10-pin connectors. These two can be led to SA-Adapters using ribbon cable, e.g. at
an additional front panel.
If the additional two UART connectors are
implemented, you cannot install an on-board SATA hard disk.

F600!
