Quick Install Windows 95/98/Me 1. With the power off, insert the LavaPort-PnP card into any free ISA slot. 2. Launch Windows95/98/ME – new hardware will be found. 3. When prompted, insert the LavaPort-PnP installation diskette and select the file “Lava.inf” in either the root or the Win95 subdirectory. (If the diskette is not found you may have to manually type “A:\WIN95\”). 4. After Windows has booted, Click the Start button, then Settings, Control Panel, System, Device Manager, Ports.
Hardware Installation 1. Before opening the casing of your computer, make sure that all power is off. 2. Locate an unused ISA slot and insert the LavaPort-PnP into it. Ensure that it is well seated. 3. Screw the metal backplane of the LavaPort-PnP board to your PC’s casing and replace the machine’s cover. 4. Connect your modem cable to the LavaPort-PnP and turn the PC on.
Windows Installation Windows Driver Installation Note: Make sure that you are installing the correct LavaPort-PnP drivers for the appropriate operating system. DO NOT install NT or Windows 3.x drivers under Windows95/98/ME 1. Once the LavaPort-PnP is installed in your PC, turn on your computer. Windows will automatically detect the LavaPort-PnP as a new Com Port and configure it for the next available Com address and IRQ (interrupt) level.
3. Click on the Start button, then choose Settings, Control Panel, System, Device Manager. Click on Ports and select the LavaPort-650 ISA. 4. Click Properties.
Setting LavaPort Data Rates 8
The data rate of the LavaPort may be set using the Bits per Second pull down menu. Please note that this menu will also appear when setting the “Port Properties” in any communications application, and may have to be set independently of your Control Panel settings. Control Panel settings may not necessarily be linked to those of your Communications Application.
Setting LavaPort FIFO Control 10
The LavaPort-PnP incorporates a 16650 UART chip with a 32-byte FIFO (first-in-first-out) buffer. The FIFO control tabs set the buffer “trigger” levels. When the buffer is filled to its trigger level with the selected number of bytes, the CPU will be interrupted and asked to either reload the buffer (for transmission), or retrieve data from the buffer (for reception). Most efficient data transmission occurs when the CPU is interrupted infrequently.
Setting LavaPort Flow Control Flow Control refers to the type of signaling that is used between the modem and the LavaPort. If you are connecting the LavaPort to a modem or ISDN terminal adapter, use the default setting of Hardware (RTS/CTS) flow control. Software Flow Control (Xon/Xoff ) is used only for connecting the LavaPort to a non-modem serial device (e.g. Using a null-modem cable to connect to another Com Port).
Com Addressing & IRQ Resources The Resources Tab will show you how the LavaPort ISA has configured itself.This tab should be used for information purposes only, and settings should not be changed.
Setting a 230.4 kbps Data Rate The LavaPort-PnP supports data rates up to 460.8 kbps, including 115.2 kbps and 230.4 kbps. However, not all modems support Com Port rates above 115.2 kbps. If your modem does not support higher data rates and you select a higher data rate in the LavaPort Properties, Windows will automatically default to the slowest supported rate in the chain. Some modems do support higher data rates but require special settings and INF files for configuration.
Lava Modem Speed Set for Windows 95/98/ME Because some modems support data rates higher than 115.2 kbps, but require special settings (AT Commands) and INF files for configuration, Lava has included a software utility called “Lava Modem Speed Set” which automates the changing of port and modem speeds.
To install the Lava Modem Speed Set utility on your hard drive, insert the LavaPort diskette into your floppy drive, click Start, Run and type A:\Utils\Setup. After installation, the program will attempt to identify your modem. When your modem is found, select it and the following screen will appear: Note that AutoBaud refers to the default speed of the modem (usually 115.2 kbps), and is the speed at which many ISDN modem configuration programs operate. Once configured, the modem may be set for 230.
