User manual LAVA LAVAPORT-PLUS

[. . . ] Click "Properties" to change the default settings as desired. If desired, install the Lava Com Port Redirect and Lava Modem Speed Set utilities to change the Com numbers of your serial ports, and to automate modem speed settings. 4 Hardware Installation 1. Before opening the casing of your computer, make sure that all power is off. Locate an unused PCI slot and insert the LavaPort-Plus into it. [. . . ] Double-click on the words Input/Output Range. The following screen will appear: 4. Use the up/down arrows to scroll to one of the following two range settings, or type them in manually: 0278 - 027F 0378 - 037F 5. After one of these has been entered, click OK. Windows will verify whether you would like to force this particular configuration rather than the automatic one that it had previously chosen. Confirm that there are no conflicts with other parallel ports already in your PC. If no conflicts are found, restart Windows. 9 Optimizing the Parallel Port for use with Iomega Zip Drives 1. Connect your Zip Drive to the Lava-Plus parallel port, and install the drive as instructed by Iomega. On the Iomega installation diskette, you will find a utility called "Parallel Port Accelerator" After the drive . Open Control Panel | System | Device Manager and find the Iomega Parallel Port Zip Interface listing under SCSI Controllers. Click Properties and go to the Settings tab. The following screen will appear: 3. The Parallel Port Accelerator Utility will have a text string inserted into the area shown on this screen. The first part of this string will read: /mode:bdir Change this string to read: /mode:epp NOTE: Do NOT change the spacing or the order of the text in the string. Doing so may result in the Zip Drive not being recognized. 10 Customizing the LavaPort-Plus Serial Ports 1. Click on Ports and select one of the ports listed under the heading LavaPort PCI. Click Properties. The following screen will appear: 11 3. A screen similar to the following will appear: Note: Do not be alarmed if Windows reports an I/O Range or IRQ conflict between the LavaPort-Plus and some other device in your PC. The LavaPort-Plus is a fully compliant PCI device, and therefore allows for the sharing of IRQ and I/O Resouces between devices. 12 The LavaPort-Plus serial port appears in Device Manager in two places: under the Multi-function Adapters tree and as part of the Ports tree. Please note that the Resources (I/O Address & IRQ) used by the LavaPort-Plus can only be modified through the LavaPort Parent device - listed under Multi-function Adapters. If you wish to change the Com number of either one of the serial ports on the LavaPort-Plus (e. g. Asssign Port 1 to be Com 3 instead of the default Com 6), please use the Lava Com Port Redirector Utility. This program will allow you to change the numbering of your ports without changing I/O address resources. Interrupt Resources may be modified for the LavaPort Parent device (see Device Manager - Multi-function Adapters), but not for individual ports because both serial ports on the LavaPort-Plus share one IRQ. Please note that interrupt changes require a reboot to take effect. 13 Changing the Com numbering of your Ports The LavaPort-Plus takes advantage of the inherent support of Windows for a multitude of Com Ports, and allows the user to add one or more ports beyond the traditional Com 4. Indeed because the LavaPort-Plus is a PCI device, Windows will always configure its serial ports using Com designations with higher numbers than Com 4. Unfortunately many communications application programs do not recognize Port designations beyond Com 4. [. . . ] If multi-tasking while online, set transmit triggers higher and receive triggers lower. 19 Setting LavaPort Flow Control in Windows 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). 20 21 Lava Modem Speed Set for Windows The LavaPort-Plus serial ports support data rates up to 460. 8 kbps, including 115. 2 kbps and 230. 4 kbps.
