The MAX490 RS422-TTL module incorporates the famed MAX490 chip for converting TTL/Serial signals to the RS-422 protocol and vice versa. Really nothing much to it, right?

Since all serial logic is FPGA based, almost any RS-422/RS485 protocol can be supported. The I/O connector is a 68 pin high density type compatible with standard 100 ohm differential cables. On card ...
