• 7I74 Eight Channel RS-422/485 interface/ RJ45 Breakout

The 7I74 is a 8 channel RS-422 interface for Mesa's 25 pin I/O FPGA cards.  The 7I74 has 8 independent receive and transmit channels.  One transmit channel has a independent drive enable for bus or 2 wire half duplex systems.  Serial I/O connectors are RJ45 jacks allowing standard CAT5 cables to be used for high speed serial links.  The 7I74 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 and all serial interfaced I/O cards.
