PCI-AC48 Adapter Card

The PCI-AC48 is an isolated, high-speed adapter card designed to link RS-485 serial devices, such as Opto 22's B3000 brains, with computers using the Peripheral Component Interconnect (PCI) bus. This adapter card is ideal for customers who have been using Opto 22's AC37 adapter card, but must upgrade to a newer computer that uses the PCI bus instead of the ISA bus.
