    Product Description

    . . . . . Opto 22 AC47 Twisted-Pair ARCNET Network Interface Card for ISA Bus Computer

    Opto 22's AC47 is a twisted-pair ARCNET network interface card for standard ISA bus computers. It provides the capability to construct a point-to-point or multidrop topology ARCNET network using twisted-pair RS-485-compatible cable. The two nodes on this adapter card can be used as separate communication ports, or they can be configured for redundant operation. For redundant data link operation, you can use dual twistedpair cable or two completely separate cables. Screw-type connectors are provided on a removable barrier strip, eliminating the need for special cable connections. RJ-11 modular jacks are also provided for convenience. In Opto 22 industrial automation systems, the primary function of the AC47 interface card is to control one or more "HA" style SNAP brains directly from a PC. In the PC-to-brain configuration, a single twisted-pair cable is daisy-chained from the AC47 interface card to each of the brains. If shielded cable is used, the shield should be connected to the ground, or common terminal, at one end only. The significant advantages of the Opto 22 I/O network based on twisted-pair ARCNET are speed, distance, and relative ease of implementation. The transfer rate of an Opto 22 ARCNET network is 2.5 megabits per second, with a total network distance of 1,000 feet without a repeater. Commercial hubs and repeaters permit virtually any size network.. Opto 22. Opto 22. AC47.
