Details
The ACCES I/O M.2-COM-2S features high performance 16C950-class UARTs. This card has 2-Ports and has 128-byte deep transmit and receive FIFOs. Large FIFOs protect against data loss in multitasking operating systems, reduce CPU utilization, and improve data throughput, while reducing or eliminating inter-character or inter-packet pauses. The advanced integrated circuit with pre-scalar supports a wide variety of custom baud rates, and any rates not otherwise achievable can be supported via a custom factory-installed crystal oscillator. RS-422, or RS-485 can be software selected, per port, and the selection is stored in non-volatile memory for future use. If you don’t need that much flexibility you can order versions with only RS422/485. RS422 mode uses the same transceivers as the RS-485 specification, allowing perfect 4-wire RS-422 and RS-485 compatibility – and the device supports full-duplex RS-485 4-wire.Ordering Info
