PCC-10 User's Guide 2-13
conforms to this standard, whether the computer is on or off. In addition, the
PCC-10 card is recognized as a UL (Underwriter’s Laboratories) Listed Accessory
and is designed to be used with UL Listed equipment.
Do not force the PCC-10 card into the PC Card slot. The PCC-10 card is keyed and
can only be inserted one way into the PC Card slot. Figure 4.4 shows the 68-pin PC
Card side of the PCC-10 card. In a Windows 95 environment, insertion of the
PCC-10 card will cause the operating system to produce two brief tones: a low tone
followed by a higher tone. Extracting the card will produce the tones in reverse
order: high and then low. If a device’s property window is open in the System
Control Panel, the tones will be produced after the window is closed to confirm that
the device is inserted correctly. Additionally, a PC Card icon may also appear in
the status area to the right of the Windows 95 taskbar. In a DOS or Windows 3.1x
environment, notification of correct card insertion is determined by the card and
socket services installed on the PC.
• If the computer was rebooted after installation of the software, insert the
PCC-10 card into an open PC Card slot. Otherwise, reboot the computer
before insertion.
• Under Windows 95, the device driver for the PCC-10 card is not loaded until
the first PCC-10 card is discovered. Likewise, when the last PCC-10 card is
removed, the device driver is unloaded, thus freeing any system resources it
was using.
• Under Windows 3.1x, the device driver is loaded at the start of Win3.1x.
Similarly, the PCC-10 system images and configuration information are read
and stored at Windows boot-time.
• Under DOS, the device driver is loaded upon booting the computer. The
PCC-10 system images and configuration information are read and stored
when the PCC-10 Card is inserted into the computer.
• Under Windows 3.1x, the L
ON
W
ORKS
PCC-10 Card Services Client must be
running in the background to use the PCC-10 card. If it is removed from the
StartUp Program Group, it must be invoked manually by double-clicking the
icon titled, “PCC-10 CS Client,” or by running the executable file named
LONCSM.EXE, which is found in the \bin subdirectory of the PCC-10 card
installation directory. This application can also be used to view the resources
allocated to the PCC-10 and control IRQ assignments.
• A PCC-10 card may not be recognized in Windows 3.1x under some card and
socket services if insertion occurs while in a DOS shell. The inserted card
may be reacquired by exiting and restarting the PCC-10 Card Manager
application.
• Each PCC-10 card requires a single, dedicated interrupt request (IRQ) and
four contiguous bytes of I/O address space starting on a modul0-4 based
address.
