Chapter 1 About the AT-1500 Plug and Play Adapter The Allied Telesyn AT-1500 Plug and Play Ethernet Adapter Card is your PC’s link to a client/server or peer-to-peer Ethernet Local Area Network (LAN). With your computer on the network, you have access to a whole new world of computing. The AT-1500 connects your computer to networked printers, allows you to share files and data bases, and take advantage of remote processing power and services like electronic mail and Internet access.
AT-1500 Plug and Play Your computer must be an IBM-PC or compatible computer with the following specifications: ❑ ISA bus (or EISA bus) computer with 16-bit slot available that supports bus mastering ❑ Compatible operating system such as Windows 95, Windows NT, Windows for Workgroups, Windows 3.
Chapter 2 Installation The Network Adapter Card The network adapter card may be considered to be a two-sided device with one side talking to your computer and the other side talking to the network. A special interpreter called the driver allows your network to communicate with your computer. The network adapter card uses an address, an interrupt request number (an IRQ), and a direct memory access (DMA) channel number to describe its logical location inside your PC.
AT-1500 Plug and Play computer is Plug and Play ready. In a non Plug and Play situation, you may need to ensure that the card is configured to work in your computer by resolving I/O resource settings. Network Software and Driver Installation Most of the network software manufacturers provide an installation program that allows you to perform the entire installation by making dialog-box choices. As part of the network installation, the install script will prompt for the adapter card driver files.
Installation Drivers for Servers. Table 2 shows the drivers for use in a server, bridge, router, or brouter. Table 2: Which Driver to Use in a Server, Bridge, Router, or Brouter Network Software Card Driver Path \Filename Windows NT \WINNT-95\AT1500M.SYS NetWare v4.0 \NETWARE.40\AT1500.LAN NetWare v3.11 \NETWARE.386\AT1500.LAN NetWare v3.1 \NETWARE.386\AT1500.LAN TIP: Network software manufacturers’ procedures and file structures are subject to change.
AT-1500 Plug and Play CAUTION This LAN adapter card is for use only with IBM or compatible UL listed personal computers that have installation instructions detailing user installation of card-cage accessories. Installation should be performed with precautions to prevent damage to static-sensitive components. NOTE The AT-1500 Plug and Play card uses the bus-mastering method for data transfers.
Installation In a non Plug and Play environment, the EISA utility asks which I/O resources to reserve for the adapter card. You can refer to Table 3 on page 13 and record the settings you choose. Installation example: Windows 95 workstation 1. Turn your computer on and boot into Windows 95. Insert the ATI CardAssistant diskette into the 3.5" diskette drive.
AT-1500 Plug and Play 8. 9. This completes the installation. To ensure that the network is accessible, follow the procedures in How to make sure your card's installed correctly. With the CardAssistant diskette in the diskette drive, type the following path in the dialog box: :\WINNT-95 where is the drive letter of the floppy drive containing the CardAssistant diskette. Windows 95 copies the driver and loads it. 10. This completes the installation.
Chapter 3 Configuring with CardAssistant Software Settings If your computer does not have Plug and Play support, or if there are non Plug and Play devices in the computer, you may need to change settings for I/O resources used by the card. Instead of hardware jumpers, the AT-1500 uses software settings to configure the card. In a non Plug and Play or legacy environment, the CardAssistant utility allows you to modify the settings for the card.
AT-1500 Plug and Play 2. Consult your computer’s instruction manual for information on adding peripherals. 3. Check I/O resources used by other peripherals. TIP: If there is not another network card in the computer, the default I/O settings are likely to work. Table 9 on page 32 lists some common conventions for ISA bus I/O. 4. Install the network software and driver. See “Network Software and Driver Installation” on page 4. 5. Insert the card in the computer.
Configuring with CardAssistant 3. Insert the installation diskette into the appropriate floppy drive. 4. Type: :setup15 where is the disk drive containing the CardAssistant program. Proceed to step 6. 5. Install CardAssistant onto your hard disk by selecting the Install command from the File menu. Once this is accomplished, you can type: path\setup15 where path\ is the optional drive and directory. 6. The main menu comes up and you are ready to select one of the icons.
AT-1500 Plug and Play CardAssistant’s main menu presents you with the choice of configuring the card or running diagnostics. Pop-up menus list the possible resource settings, with the current setting highlighted. The message window under the menu lists available commands. Changing AT-1500 Software Settings. If there are no other adapter cards present in the computer, the likelihood of a conflict is slight. In this case, use the Auto Configure option.
Configuring with CardAssistant 1. Launch CardAssistant. If your primary operating system is Windows 3.x, Windows for Workgroups 3.x, Windows NT 3.1, or DOS, run the DOS version of CardAssistant. See “Running CardAssistant in DOS Mode” on page 10. If your primary operating system is Windows 95 or Windows NT 3.5x, run the 32-bit Windows version of CardAssistant. See “Running CardAssistant in 32-bit Windows Mode” on page 11. 2. Choose “Configure I/O Parameters” or “Auto Configure” from the main menu.
AT-1500 Plug and Play 6. When you are satisfied with the settings for all resources, press F10 (DOS version) or Save configuration (32-bit Windows version) to accept your changes. You do not have to reboot the computer. Full Duplex Operation By default the card works in half duplex mode. In this mode, the card can at a given time either send or receive data, but not both.
Configuring with CardAssistant NOTE Diagnostics runs in DOS mode with no drivers loaded. comment out the driver line in the batch file (for NetWare) or the DEVICE=drivername line in config.sys (for an NDIS driver) and restart the PC. 1. Boot the computer into DOS. Launch CardAssistant by typing: :setup15 ENTER where is the diskette drive containing the CardAssistant program. 2. Select the Diagnostics menu by typing: d ENTER .
AT-1500 Plug and Play Table 4 lists the parameters that may be set.
Configuring with CardAssistant The /E parameter is a specialized switch that tells CardAssistant to return the number of AT-1500 Plug and Play adapter cards installed in the computer instead of executing the setup program. This switch should be used on its own (i.e., without specifying other parameters). One handy use is for a batch file that determines which kind of card is installed and then loads the right driver. For example, the following AUTOEXEC.
AT-1500 Plug and Play The /CR and /CW parameters are used instead of the commandline configuration switches to create a configuration file that setup15 can use to configure subsequent cards. You use the /CW switch to create a file from an adapter card and the /CR switch to configure a card by reading the configuration from the file. Alternatively, you can create a configuration file using a text editor. This file is an ASCII file that must contain ALL parameter values IN ORDER.
Configuring with CardAssistant When configuring cards using command-line parameters, setup15 can configure only one AT-1500 Plug and Play card at a time. If multiple boards are to be installed, either run CardAssistant interactively, or use a configuration file. NOTE CardAssistant counts cards when it runs. This count correlates to the “board instance” parameter in the configuration file. The cards are counted by base I/O address in descending order (from the highest address to the lowest). e.g.
AT-1500 Plug and Play If the card is not functioning correctly, the problem may be caused by a configuration that conflicts with other accessories installed in the workstation or server. In this case, refer to “Troubleshooting,” Chapter 5. Boot ROM Socket The AT-1500 Plug and Play card is shipped with an unpopulated boot ROM socket. For a diskless workstation, the card needs a boot ROM to allow it to load the operating system over the network.
Chapter 4 Cabling 10BASE-T, 10BASE2, 10BASE5, or 10BASE-FL Choices The T, BT, AT, and FT versions of the AT-1500 Plug and Play all have a shielded RJ45 receptacle for connection to 10BASE-T network segments. The AT-1500 Plug and Play is compatible with 100 Ω Unshielded Twisted Pair (UTP) or Shielded Twisted Pair (STP) wire.
AT-1500 Plug and Play 10BASE-T UTP/RJ45 Cabling The AT-1500T Plug and Play adapter card is for use with 10BASE-T segments, using an 8-wire (4-pair) RJ45 jack for the network cable, shown in Figure 2. Figure 2: AT-1500T Plug and Play UTP Port and RJ45 Connector Important 10BASE-T Cable Considerations. There are various grades of voice-quality and data-quality cables available. The five common modular cable specifications and their applicability to 10BASE-T network use are shown in Table 6.

Cabling an RJ45 Connector 10BASE2 RG58/BNC Cabling In addition to an RJ45 connector, the AT-1500BT Plug and Play adapter has a BNC connector for 10BASE2 standard thin Ethernet RG58 coaxial cable. The maximum segment length is 185 meters (606 ft.), and the minimum length between nodes is 0.5 meters (1.64 ft.). The coaxial cable should be connected to the adapter card via a T-connector and must be terminated with a 50 Ω BNC terminator if the computer is at the end of a network segment. See Figure 5.
AT-1500 Plug and Play 10BASE-FL/FOIRL (Optical Fiber) Connection The AT-1500FT Plug and Play provides both an RJ45 for 10BASE-T Ethernet and ST-type transmit and receive connectors for 10BASE-FL or FOIRL Ethernet network segments. Maximum segment length is 1000 meters (3279 ft.) for FOIRL and 2000 meters (6558 ft.) for 10BASE-FL. (See Figure 7.) NOTE Hazardous light emissions may exist in fiber optic systems. Severe eye damage may result if precautions are not taken.
Cabling 10BASE5 (AUI) Connection The AT-1500AT Plug and Play adapter offers both an RJ45 and an AUI port. (See Figure 8 and Figure 9.) Figure 8: AUI Connector for Thicknet Drop Cable Figure 9: AUI Connector for Direct Transceiver Connection In Figure 8, you see a drop cable from a remote transceiver, typically on a thicknet backbone. In Figure 9, you see the transceiver installed directly on the AUI port.

Unless the transceiver is installed on a device that specifically requests that the heartbeat/SQE switch be ON, this switch should be set to OFF.
Chapter 5 Troubleshooting A network is a complex combination of hardware and software, all of which must function for data communication to work. Problems are most likely to occur when the card is first being installed or when someone changes something in the network. A problem could be caused in your computer or in cabling or in many places elsewhere in the network.
AT-1500 Plug and Play Experiment with Possible Solutions This chapter provides the common factors to check in troubleshooting. It is by no means exhaustive since there are too many environmental factors to take into account. The first rule of troubleshooting is to isolate the problem. As you experiment, vary only one factor at a time. Substitute known good equipment and see if the problem persists or is eliminated.
Troubleshooting ❑ If CardAssistant software does not detect the card, it could mean a conflict between the card and another device, a card failure or a slot failure. You may need to reconfigure the adapter card or the other device to avoid the conflict. Only one device in the computer can use each I/O port, DMA channel and interrupt vector. If two (or more) devices try to share resources, one or all do not function properly. Table 9 lists common uses of resources that can cause conflict.
