• The AC5 and G4AC5 are compatible with ISA bus-based PCs and can control up to 24 I/O points on a single mounting rack.
  
  
• The PCI-AC5 is compatible with computers that feature a 33 MHz Peripheral Component Interconnect (PCI) bus. With two 50-wire ribbon cable interfaces, it can control up to 48 I/O points (24 per rack).

The PCI-AC5 offers expanded operation with the faster PCI interface, using high-speed 32-bit memory access for high throughput. The PCI-AC5 is about 100 times as fast as the AC5 in accessing I/O using the free Opto 22 PCI-AC5/AC5 Toolkit. The PCI-AC5 also has jumperless configuration and four LEDs for debugging or indicating application status.

Traditional PC 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 of today’s personal computers.

The PCI-AC48 is compatible with computers that feature a standard 33 MHz 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 rather than the ISA bus.

Two RS-485 serial ports provide reliable communication. These ports can be used as two 2-wire ports or as one 4-wire port (twoand four-wire modes cannot be used at the same time). Buffering on the card prevents loss of data, and the serial communication lines and the adapter card itself are isolated from transient voltages.

The adapter card also provides tri-state control in hardware, 64-byte FIFO, and 16550 UART-compatible registers.
