7i44 - 8 Channel RS-422/485 interface/ RJ45 Breakout

The 7I44 is a 8 channel RS-422 interface for Mesa s Anything I/O series of FPGA interface cards. The 7I44 has 87I44 picture independent receive and transmit channels. Each transmit channel has a independent drive enable for bus or 2 wire half duplex systems. The controller connection is a 50 pin header that matches the pinout or the 4I34M, 4I38, 4I65, 4I68, 5I20, 5I22, 5I23, 7I43 and 7I60 Anything I/O cards. Serial I/O connectors are RJ45 jacks allowing standard CAT5 cables to be used for high speed serial links. The 7I44 also supplies 5V power on the RJ 45 connectors. PTC devices limit maximum 5V current to 1A . The pinout used is compatible with Mesa's 3C20 motion controller and the 8I20, 8I21 serially connected amplifiers.
