User manual LAVA LAVAPORT 650

[. . . ] Before opening the casing of your computer, make sure that all power is off. Locate an unused PCI slot and insert the LavaPort-650 into it. Screw the metal backplane of the LavaPort-650 board to your PC's casing and replace the machine's cover. Connect your modem cable to the LavaPort-650 port and turn the PC on. Screw for attaching card bracket to PC casing Port PCI Slot 4 Windows Installation Note: Note: Make sure that you are installing the correct LavaPort-650 drivers for the appropriate operating system. [. . . ] You may physically modify the I/O Range and IRQ used by the LavaPort 650 by de-selecting the "Use Automatic Settings" check box, and double-clicking the appropriate heading, or: 2a. For Windows95/98/ME, you may use the Lava Port Redirect Utility provided in the Utils subdirectory of your LavaPort diskette. This utility may be run from the diskette or installed onto your hard drive. To install the Lava Port Redirect utility on your hard drive, insert the LavaPort diskette into your floppy drive, click Start, Run and type A:\Utils\Setup. The Lava Port Redirect Utility will allow you to change the Com number assigned to the LavaPort 650 (e. g. Change Com5 to Com 4) without modifying I/O resources. 2b. For Windows2000/XP, you can change port numbers by Right Clicking My Computer > Properties > Hardware > Device Manager > double click the Lava Port you want to change > Port Settings > Advanced and under Com Port Number, you can change the port number from the drop down menu. 9 Setting LavaPort Data Rates in Windows 10 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. For example, Port speeds in Dial-Up Networking are controlled independently of speed settings in Device Manager. For optimum performance, always verify that your LavaPort is set to the maximum speed supported by your modem, and that all speed settings are the same in every application. Please note that the setting of Communications Port Data Rates is often the most confusing of tasks encountered by modem users. For this reason, Lava has included the Lava Modem Speed Set utility in the Utils subdirectory of your LavaPort diskette. Lava strongly recommends using this utility for all LavaPort-to-modem connections (described later). 11 Lava Modem Speed Set for Windows The LavaPort-650 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 (AT Commands) and INF files for configuration. Lava has included a software utility called "Lava Modem Speed Set" which automates these functions and allows for easy speed reconfiguration. This utility may be found in the Utils subdirectory of your LavaPort diskette, and is constantly being updated to support more modems. Please check the Lava Web site for details: www. lavalink. com 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. 12 13 Setting LavaPort FIFO Control in Windows 14 The LavaPort-650 uses a 16650 UART incorporating a 32-byte FIFO (firstin 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). [. . . ] Once the LavaPort-650 is installed in your PC, turn your computer on and start NT. Place the LavaPort installation diskette into your floppy drive and select Run from the Start Menu. After the necessary files have been copied, select My Computer and start Control Panel. A new icon will appear called "LavaPort" . This applet should now be used to configure ALL Com Ports in your PC not just LavaPorts. 17 Please note that Com 1 may not appear in this applet if you have your mouse attached to Com 1. Setting a 230. 4 kbps Data Rate The LavaPort-650 supports data rates up to 460. 8 kbps, including 115. 2 kbps and 230. 4 kbps. [. . . ]
