DASCard-PIO12 features and operating characteristics are described as
follows:
● The DASCard-PIO12 has three TTL/NMOS/CMOS-compatible,
digital I/O ports: port A, port B, and port C. Ports A and B are both
byte-wide (8-bits) and can be inputs or outputs. Port C is also
byte-wide but is usable as two separate 4-bit ports (port C Lower and
port C Upper), which can be an inputs or outputs.
● The DASCard-PIO12 has an interrupt input channel. During startup,
the Keithley MetraByte Enabler program can request any one of the
interrupt levels available on the PC bus.
● The Interrupt Controller of the computer handles interrupts and is set
by the computer BIOS to respond to positive-edge-triggered (low to
high) inputs. You must program the Interrupt Controller to respond to
your application by setting up the corresponding interrupt handler.
● The DASCard-PIO12 decodes 2-bit I/O addresses and communicates
with the PC bus as an 8-bit peripheral. The address map uses four
consecutive I/O addresses. You can install multiple DASCard-PIO12
cards in a computer with each at a different base address.
● The +5 V power level from the computer is available through the
main I/O connector of the DASCard-PIO12 cable. If you plan to use
power from the PC Card, you should consider the power draw of all
system devices and observe current-capacity limits of both the
computer and the card.

Using the Configuration Utility
You need a configuration file to use the Function Call Driver or VTX,
provided in your DASCard-PIO12 software package. The CFGPIO.EXE
configuration utility allows you to create a new configuration file or
modify an existing configuration file. CFGPIO.EXE also allows you to
create a configuration file for multiple PIO devices.
Creating or Modifying a Configuration File
Use CFGPIO.EXE to create or modify a configuration file, as follows:
1. In Windows, select the PIO-Configuration icon in the Keithley PIO
program group.
2. To modify an existing configuration file, select the Open option from
the File menu, select the configuration file (for demonstration
purposes, choose the PIO.CFG file from the ASO-PIO software
package), then go to step 3. To create a new configuration file, go to
step 5.
3. In the PIO Configuration panel, select the DASCard-PIO12 from the
Board Type scroll bar. The default configuration options for the
DASCard-PIO12 are as shown in Table 3-1.
Table 3-1. Default Configuration Options for the
DASCard-PIO12
Attribute Options
Card name DASCard-PIO12
Base address (hex) —

Port A, B, CL, and CH Input
Combine ports No
4. Use the Save option in the File menu of the PIO Configuration panel
to save these options in the PIO.CFG file, making this file your
default configuration file for the DASCard-PIO12.
3-4 Setup and Installation
5. You can create a new configuration file by modifying the default
configuration values in the PIO Configuration panel and using the
Save As selection from the File menu of the PIO Configuration panel
to save the modified values in a file with a new name. For consistency,
any name you assign to a configuration file should have a .CFG
extension (for example, MYFILE.CFG).
Creating a Configuration File for Multiple PIO Devices
In a laptop computer, CFGPIO.EXE can support a maximum of two
DASCard-PIO12 cards in PCMCIA sockets. In an IBM PC AT (or
equivalent), CFGPIO.EXE can support a maximum of 10 PIO devices.
Up to two of these PIO devices can be DASCard-PIO12 cards in
PCMCIA sockets; the remaining devices can be any of the various PIO
boards in the accessory slots of the computer.
When you are working with multiple PIO boards and cards, you use the
configuration utility to assign each board and card a board number from a
range of 0 to 9. You can assign each of two DASCard-PIO12 cards any
number in this range, so long as you assign a card in PCMCIA socket 0 a
lower board number than a card in PCMCIA socket 1 (if you use just one
DASCard-PIO12, you must place the card in socket 0). Use
CFGPIO.EXE to configure a mix of PIO boards and cards as follows:
1. In Windows, select Run from the Program Manager File menu, use
the Browse button to find CFGPIO.EXE, and choose OK in both the
Browse and Run panels.
2. In the Board No. scroll box of the PIO Configuration panel, select
board number 0.
3. In the Board Type scroll box of the PIO Configuration panel, select
the type of board or card you have designated as board number 0.
4. Modify the configuration options for the board or card designated as
board number 0.
Note: Remember that you must set each PIO board for a different
base address and interrupt level, and that you must enter the base
address and interrupt level for each board in the configuration options
for the corresponding board number (the base address and interrupt
level for a DASCard-PIO12 allocated by the Enabler).
3-5
5. When the configuration options for board number 0 are complete,
repeat steps 2 to 4 for each of the remaining boards/cards.
6. When the configuration options for all boards/cards are complete, use
the Save As selection from the File menu of the PIO Configuration
panel to save the options in a new or existing configuration file.
7. To exit the configuration utility, choose the Exit option on the PIO
Configuration panel.
Loading the Keithley MetraByte Enabler Utility
A PC Card enabler is a TSR whose function is to set up compatibility
between the card and the computer bus by requesting PCMCIA Card
Services to allocate certain resources for the card. These resources
include a base address and an interrupt level for the DASCard-PIO12.
Most computers equipped to accept PC Cards contain a generic enabler
that loads automatically upon startup. However, PC Card manufacturers
often provide customized enablers to perform tasks a generic enabler
might be unable to handle. Keithley MetraByte provides
KMENABLE.EXE, a customized enabler designed to recognize and
respond specifically to Keithley MetraByte PC Cards. You must use the
Keithley MetraByte Enabler for your DASCard-PIO12 if you intend to
use VTX, the Control Panel, or the PIO Series Function Call Driver.
To obtain a base address and interrupt level that are not in use by another
device in your system, perform the following steps to load the Keithley
MetraByte Enabler:
1. Turn power to your computer off.
2. If your DASCard-PIO12 is already installed, remove it from its
socket.
Note: To prevent conflicts with the generic enabler or with Windows,
do not install your card or load Windows until after you load the
Keithley MetraByte Enabler.
3. Return power to the computer.
3-6 Setup and Installation
4. If your PCMCIA Card Services allow you to exclude resources from
resource allocation, make sure you exclude any base addresses and
interrupt levels in use by other devices in your system.
5. If your PCMCIA Card Services allow you to reserve system
resources, make sure that you reserve a base address and interrupt
level not in use by other devices in your system.
6. Table 3-2 lists the command-line switch options for use with the
Enabler. Use these switch options if the default values for base
address and interrupt level are already assigned to another device.
7. If the default base addresses and interrupt levels shown in Table 3-2
are available, go to step 9.
8. If the default base addresses and interrupt levels shown in Table 3-2
are unavailable, go to step 10.
9. Load the Keithley MetraByte Enabler using the following statement
at the DOS prompt, and then go to step 11:
KMENABLE
Note: If you prefer to start the Keithley MetraByte Enabler
automatically upon power-up, enter the KMENABLE command in
your computer’s AUTOEXEC.BAT file. Remember, though, to
remove your card before power-up.
10. Load the Keithley MetraByte Enabler using one or more of the
command-line switch options listed in Table 3-2.
Table 3-2. Switch Options for the Enabler
Switch Syntax Description
/? Displays syntax information.
/BA0:baseaddress Uses the value you enter for baseaddress to specify
a base address for card 0. Make sure that &H
precedes hexadecimal numbers. If you do not use
this switch, the Enabler tries to use a default base
address of 300h.
3-7
Table 3-2. Switch Options for the Enabler (cont.)
Switch Syntax Description
/BA1:baseaddress Uses the value you enter for baseaddress to specify
a base address for card 1. Make sure that &H
precedes hexadecimal numbers. If you do not use
this switch, the Enabler tries to use a default base
address of 308h.
/I0:intlevel Uses the value you enter for intlevel to specify an
interrupt level for card 0. If you do not use this
switch, the Enabler tries to use a default level of 5.
If you use a value of −1, the Enabler does not
allocate any interrupt level.
/I1:intlevel Uses the value you enter for intlevel to specify an
interrupt level for card 1. If you do not use this
switch, the Enabler tries to use a default level of 7.
If you use a value of −1, the Enabler does not
allocate any interrupt level.
/MEM0:memaddress Not applicable.
/MEM1:memaddress Not applicable.
/NORETRY
/U Unloads the Enabler from computer memory.
Notes
1
An error detected by the Enabler is displayed when you run the diagnostics
utility (see page 3-10). If the error is displayed in one of the following 4-digit
formats, the error indicates an allocation problem with the named resource:
8xxx indicates base address; 4xxx indicates interrupt level; Cxxx indicates
memory.
The Enabler detects an error1 if the base address or
interrupt level you specify is in use by another
Keithley MetraByte PC Card. If you do not use this
option and specify a resource that is assigned to
another Keithley MetraByte PC Card, the Enabler
automatically selects the next available resource.
For example, if the default assignments for card 0 are appropriate but
you want to change the assignments for card 1, enter a line similar to
the following at the DOS prompt:
KMENABLE /BA1:&H310 /I1:11
3-8 Setup and Installation
As another example, if you want to change a base address and/or
interrupt level without restarting your computer, you can remove the
Keithley MetraByte Enabler by entering the following statement at
the DOS prompt:
KMENABLE /U
Then (after removing the card and exiting Windows), you can reload
the Enabler using the command-line switch options to specify a new
base address, and/or interrupt level. Replace the card after you load
the Enabler.
Still another example uses the /NORETRY switch to make sure the
same base address and interrupt level are allocated each and every
time the card is inserted. This switch allows the use of older PIO-12
boards as well as register-level programming. Use this switch with a
command similar to the following:
KMENABLE /BA1:&H310 /I1:11 /NORETRY
Note: If you use the PCMCIA software to reserve system resources
and then use a switch option to specify a base address or interrupt
level that was not reserved, the value you specify is ignored.
11. To determine whether the Enabler recognizes your DASCard-PIO12
and whether suitable resources were allocated, install your card (see
the next section) and run the diagnostics utility (see page 3-10).
Installing the Card
To install a DASCard-PIO12, perform the following steps:
1. Select the appropriate Type II, PCMCIA socket and remove its cover.
2. Insert the card into the selected socket; the card is labeled to show the
direction of insertion and keyed to allow only one way of insertion.
On some computers, one or more beeps indicate that the card is
installed correctly.
If you are using two DASCard-PIO12 cards, the Keithley MetraByte
Enabler recognizes the first card you install as card 0 and the second
as card 1, regardless of socket numbers.

3. On most notebook computers, you can hot-swap PC Cards; you are
not required to turn computer power off when installing or removing
a card. A computer that does not conform to the ExCA (exchange
card architecture) Specification cannot support hot swapping; you
must turn on the PCMCIA socket with a software utility each time
you insert a card. The socket turn-on utility should be described in
your computer documentation.
4. Make sure the card is ready for proper operation by running the
diagnostics utility; refer to the following section.
When your DASCard-PIO12 is properly installed, you can attach
accessories and wire signals to the card; refer to Chapter 4 for
information.
Using the Keithley MetraByte Diagnostics Utility
The diagnostics utility (KMINFO.EXE for DOS or KMINFOW.EXE for
Windows) allows you to check the status of your DASCard-PIO12 after
startup and during operation. To check the operation of your
DASCard-PIO12 while running in DOS, enter the following command at
the DOS prompt:
KMINFO
To check the operation of your DASCard-PIO12 while running in
Windows, use KMINFOW.EXE as follows:
1. Choose Run from the File menu of the Program Manager panel to
bring up the Run panel.
2. Choose Browse to locate and select KMINFOW.EXE.
3. Choose OK on both the Browse and Run panels to run the utility.
The diagnostics utility displays the following information:
● The PCMCIA Card and Socket Services that are installed
● Whether the Keithley MetraByte Enabler is installed
3-10 Setup and Installation
● The following information for each socket:
– The manufacturer of the installed card
– The card type
– Whether the card is enabled
– If the card is enabled, the base address and interrupt level
– If the card is not enabled, Card and Socket Services and the card
identification
Note: The diagnostics utility displays a base address as a number
preceded by 0x. The 0x signifies a hexadecimal number. For example,
0x350 is 350h.
If any of the fields in the diagnostics display are missing or if an error is
displayed, the card is improperly configured. Refer to Chapter 7 for
troubleshooting information.
An error displayed in one of the following 4-digit formats indicates an
allocation problem with the named resource: 8xxx indicates base address;
4xxx indicates interrupt level; Cxxx indicates memory.

Programming
Note: You can ignore this chapter if you are using ASO-PIO software. If
you are not using ASO-PIO software (if you are programming in DOS, or
if you are using existing software for the older PIO-12 board, or if you are
doing register-level programming), you must use the /NORETRY switch
(see Table 3-2 on page 3-7) to make sure you get the same base address
and interrupt level each and every time you install your card.
DASCard-PIO12 programmability is provided through the card's 82C55
Programmable Peripheral Interface (PPI) integrated circuit. The 82C55
PPI provides 24 digital I/O lines, which the DASCard-PIO12 uses for the
following three ports:
● Port A (abbreviated PA) consists of one 8-bit data output latch/buffer
and one 8-bit data input latch.
● Port B (PB) consists of one 8-bit data output latch/buffer and one
8-bit data input buffer.
● Port C (PC) consists of one 8-bit data output latch/buffer and one
8-bit data input buffer. This port can also be used as two 4-bit ports:
PC Upper (PC4 to PC7) and PC Lower (PC0 to PC3).
Programming the DASCard-PIO12 involves two fundamental tasks:
1. Setting the port configuration.
2. Reading/writing data from/to the ports.
These tasks are discussed in the sections that follow.
6-1
Note: If you need more detailed information on the functionality of the
82C55 PPI, please contact an Intel® or Toshiba® representative for a
complete data sheet. The contact number for Intel technical support is
(800)628-8686.
Setting the Port Configuration
You configure each port or half-port as an input or an output according to
the value of the control word in the PPI control register. The control word
is a 1-byte word programmed at Base Address +3h. Refer to Table 6-1 for
the complete 82C55 PPI address map.
Table 6-1. 82C55 PPI Address Map
Address Function Type
Base Address +0h Port A (PA) Read/Write
Base Address +1h Port B (PB) Read/Write
Base Address +2h Port C (PC) Read/Write
Base Address +3h Control Word Write only
The control word also specifies one of the following three operating
modes (for a complete description of the PPI operating modes, refer to the
Intel 82C55 data sheet):
● Mode 0 - Basic I/O; all ports are I/O ports.
● Mode 1 - Strobed I/O; part of Port C controls data transfer.
● Mode 2 - Bidirectional I/O on Port A only; part of Port C controls
data transfer.
A power-up or reset automatically configures all ports as inputs. This
configuration remains intact until changed by a write to the control
register. The initialization section of your program should set the port
configuration. Table 6-2 illustrates how the port configuration is derived
from the control word.

A noteworthy characteristic of the 82C55 PPI is that all port registers are
cleared by a write to the control register. Consequently, if your program
intends to repeatedly change the port configuration, you may need to
make provisions for restoring data to cleared ports.
Reading/Writing Data from/to the Ports
The examples in this section use the QuickBasic programming language
to illustrate some common programming tasks.
Writing to the Control Register
The following code configures all of the ports as outputs:
OUT BADDR +3, &H80 ’Sets all ports to outputs.
6-4 Programming
Performing Fundamental I/O Operations
The following code performs fundamental I/O operations:
OUT BADDR, &H22 ’Sends 22 Hex to Port A.
OUT BADDR +1, 99 ’Sends 99 to Port B.
PRINT INP(BADDR +1) ’Reads and displays
’Port B data in decimal.
PRINT HEX$(INP(BADDR)) ’Reads and displays
’Port A data in hex.
Reading BCD Data
The following code reads 2-digit BCD (Binary Coded Decimal) data:
BCD% = INP(BADDR) ’Read data.
’Convert to decimal.
BCD% = (BCD% AND &HF0)*10/16 + (BCD% AND &H0F)
Performing Bit Operations
Bit operations use the Boolean operators OR, AND, XOR, EQV, IMP, and
NOT.
The following code sets bit 3 on Port A to 1 without disturbing the other
bits:
A% = INP(BADDR) ’Read port A.
OUT BADDR, (A% OR 2^3) ’OR bit 3 and write to
’Port A.
The following code clears bit 7:
A% = INP(BADDR) ’Read port A.
’AND the inverse of bit 7,
’effectively masking it
’to an OFF state.
OUT BADDR, (A% AND NOT(2^7))
Reading/Writing Data from/to the Ports 6-5
The following code illustrates the use of the BASIC WAIT command to
wait for a particular condition on Port C:
WAIT BADDR +2, N%, J%
The result of an XOR on the data read at Port BADDR +2 (Port C in this
example) and J% is ANDed with N%. If the result is 0, the program loops
back and reads the port again; otherwise execution continues with the
next line.
