PCI Analog/Digital Interface (PCI-ADI)

Our PCI-ADI interface provides an easy-to-install, commercial off-the-shelf (COTS) solution for replacing your system’s legacy SelBUS ADI board. The PCI-ADI connects a PCI-based host to one or more legacy RTP Corporation analog/digital subsystems. Communication to the subsystems is via the existing RTP Serial Interface.

 

Serial ports on the dual-channel PCI-ADI connect to RTP Serial Interface boards using existing coaxial cables. The PCI-ADI faceplate contains 6 LEDs indicating the power, operational, and transmission status.

 

The PCI-ADI plugs into a 32-bit PCI bus slot up to 66 MHz and is compatible with 3.3V and 5V PCI signaling levels. The edge connector of the PCI-ADI is keyed as a Universal Add-In board.

Characteristics

 

The PCI-ADI has the following characteristics:

 

  • Complete compatibility with RTP Serial Interface 1 and 2 boards
  • ROM Simulator Port pin compatibility with legacy ROM simulator and diagnostic processor boards
  • ROM Simulator Port pin compatibility with legacy ROM simulator and diagnostic processor boards
  • ADI FPGA is functionally identical to the legacy SelBUS ADI board (part numbers 160-103054-00x and 160-103813-001)
  • Two 10-megabit per second serial ports
  • Drive and receive capabilities for coaxial cable lengths up to 250 feet
  • Communication to the host system via mailbox registers accessible from the PCI bus
  • Access to host memory through PCI initiator memory access
  • PCI target interface receives commands from host system
  • Automatic status posting
  • Support for command chaining, transfer in channel, continue on non-present memory error, random mode, sequential mode, and repeat mode
  • PCI scatter/gather support accomplished by host-programmed page table entries
  • Operates in a 32-bit 3.3V/5V PCI expansion slot
  • LCRS interrupt state support
