You can easily find one and two-port cards. But engineers who needed an extra port have traditionally been forced to use another backplane slot to get it, or else to suffer the clumsiness and clutter of "octopus" cables.
Now, those who need an extra port can easily fit it onto a single slot. Our CYB 3232P (PCI) and CYB 3232A (ISA) cards offer maximum data rates of 115,200 baud, 16-byte FIFO buffers on each port, and operating temperatures from 0 to 70°C (32 to 158°F).
The PCI card is fully Plug-and-Play. ISA slots require card configuration, but the user-friendly manual for the ISA card (CYB 3232A) includes detailed configuration instructions.
Both cards come with an extensive collection of applications programs and drivers on CD. Supported operating systems include DOS, Windows 3.x, 95, 98, NT3.51, NT4, and OS/2. In addition, drivers for Windows 2000 are provided with the PCI card.
The software supports not only these two cards, but also all of the other serial communication cards in the CyberResearch CYB, CYBD, and CYBM families. Software drivers support any mix of RS-232, RS-422, and RS-485 handshake schemes, along with all baud rates available from these PCI, PCMCIA, and ISA cards.
Test and terminal-emulation software for the cards is provided in both compiled form and source-code form. The terminal-emulation source code is documented to show the action of each programming function.
