CHAPTER 4: Hardware Installation

The 5250 PCMCIA Adapter Card is supplied with a self-terminating twinax cable assembly. There is a small 15-pin connector which is plugged into the 5250 PCMCIA Adapter Card. This connector is keyed and can only be plugged in one way. Please observe the keying and do not force the cable into the connector. It is recommended that the twinax cable assembly be attached to the 5250 PCMCIA Adapter Card prior to applying power to the computer. There is electronic circuitry within the cable assembly.

CAUTION

Use only the twinax cable supplied with the 5250 PCMCIA Adapter Card, do not attempt to attach any other cable to the adapter.

The twinax cable from the host system can be connected to either twinax connector at the other end of the T-cable. The T-cable is self-terminating and will provide the proper termination if this device is the last workstation on the line. The T-cable can support the cable-through function when another twinax cable is connected to the open twinax connector.

4.2.3.2 Windows 95/98 Configuration

Card Services is an integral part of Windows 95/98 and will automatically configure the 5250 PCMCIA Adapter Card. The configuration information can be observed by using the Device Manager and selecting the 5250 PCMCIA Adapter Card. The CEM5250.VXD is installed by Windows 95/98 the first time it sees the 5250 PCMCIA Adapter Card and will provide the interface between Windows 95/98 and the adapter. There are no resource configuration requirements.

When starting Windows 95/98, the operating system checks for any new hardware devices. The first time Windows 95/98 is started after the 5250 PCMCIA Adapter Card has been installed, the message New Hardware Found will appear in a dialog box. Under this message, the new hardware will be identified; in this case it will have found the 5250 PCMCIA Adapter Card. Another dialog box will then open asking the user to install the software for the adapter. Place the Windows Utility diskette in the floppy drive, select the drive letter and press <ENTER>. The .INF and VxD drivers will be copied into the proper Windows 95/98 directory. The VxD will interface with Windows 95/98 and automatically pass the card resource information to the Windows Emulation program, Adapter Handler, or IBM Client Access.

To observe the resources assigned by Windows 95/98 for the adapter, click on Start, then Settings, then Control Panel, and then double-click on System. Click on the Device Manager tab, then double-click on 5250 Emulation Adapters. There will be an entry for the 5250 PCMCIA Adapter Card. Double-click on this entry and then select the Resources Tab. The display will now show the 5250 PCMCIA Adapter Card resources.
