DB25F (RS422) to DB9F (Opto 22) Converter

The DB104 is designed to convert a Sealevel RS-422 or RS-530 DB25 male connector to a pinout compatible with Opto 22 AC24AT and AC422AT ISA bus cards. This allows Optomux devices to be controlled from any Sealevel RS-422 or RS-530 board with a DB25 male connector.
