Opto 22 PCI-AC48 PCI Bus to RS-485 Serial Traditional PC Adapter Card, 2500 VAC Transient (PCIAC48) Serial Adapter

Opto 22 PCI-AC48 PCI Bus to RS-485 Serial Traditional PC Adapter Card, 2500 VAC Transient

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. The PCI-AC48 adapter card requires 5 VDC at 600 mA (provided by the PCI bus) and operates at temperatures of 0 degree C to 70 degree C. The card is configured using DIP switches. Six LEDs on the card indicate bus operation or user application status.
