This manual describes the PCI-AC48, an isolated, high-speed adapter card designed to link RS-485 or RS-422 serial devices, such as Opto 22’s B3000 brains, with computers using the Peripheral Component Interconnect (PCI) bus. The PCI-AC48 is compatible with computers that feature a standard 33 MHz PCI bus. This adapter card is ideal if you have been using Opto 22’s AC37 adapter card in an application, but must upgrade to a newer computer that uses the PCI bus rather than the ISA bus.
