QUESTION

How do I determine the FIFO buffer size available in NPort devices, Multiport Serial Boards (MSBs), and async. servers?

SOLUTION

The FIFO buffer size in Moxa products depends on the type of UART used. Our NPort, MSB, and async. servers use a variety of UARTs. Refer to the following table for details on the FIFO buffer size.
