Page 9: Introduction
(external interrupt available) System Configuration The figure below illustrates a complete IOP-241 system. For users that do not wish to interface to the IOP-241 0.8mm I/O connector, an optional adapter cable (CP-1037) is available to convert this connector into an industry standard D-37 connector. For applications requiring discrete wiring hook-ups, an optional screw terminal block (UIO-37) is available to convert the D-37 connector into 37 single screw terminal blocks. -
Page 10: Dos / Windows 3.X Installation
Client Driver will display an error message if Card and Socket Services software is not detected. IOP-241 Client Driver for DOS In order to use the IOP-241 Client Driver, the system must be configured with Card and Socket Services software. (Card and Socket Services software is not provided with the IOP-241). -

CONFIG.SYS file. 7. Reboot the system and note the message displayed when the IOP-241 Client Driver is loaded. If the Client Driver reports an "invalid command line option", correct the entry in the CONFIG.SYS file and reboot the system again. -
Page 12: Command Line Options
A single command line argument is provided. The Client Driver will attempt to configure an IOP-241 inserted into socket 0 with a base address of 300H and IRQ 5. If address 300H or IRQ 5 are unavailable, the IOP-241 will not be configured. In addition, if an IOP-241 is inserted into any other socket, it will not be configured. - Page 13 A single command line argument is provided. Because the parameter order is not significant, the Client Driver will attempt to configure an IOP-241 inserted into any socket with a base address of 300H and IRQ 11. If address 300H or IRQ 11 are unavailable, the IOP-241 will not be configured.

Page 14: Common Problems
Many Card and Socket Services packages include a generic client driver (or SuperClient) which configures standard I/O devices. If one of these generic client drivers is installed, it may configure the IOP-241 causing the client driver to fail installation. In these cases, the user should do one of the following: 1. -
Page 15: Iop-241 Enabler For Dos
IOP-241 Enabler for DOS For systems that are not operating PCMCIA Card and Socket Services software, the IOP-241 DOS Enabler may be used to enable and configure the card. This Enabler, IOP241EN.EXE, will operate on any DOS system using an Intel 82365SL or PCIC compatible PCMCIA host adapter including the Cirrus Logic CL-PD6710/6720, the VLSI VL82C146 and the Vadem VG-365. -
Page 16: Enabler Installation
NOTE: Since the IOP-241 Enabler does not support "Hot Swapping", it is necessary to have the IOP-241 installed when booting the system. 7. Reboot the system and note the message displayed when the IOP-241 Enabler is loaded. If the Enabler reports an "invalid command line option", correct the entry in the CONFIG.SYS file and reboot the system again. -
Page 17: Command Line Options
No command line argument is specified. The Enabler will report an error and display the proper usage of the command. 2.2.2.2 Example 2 The Enabler will configure the IOP-241 in socket 0 with a base address of 300H and IRQ 5 using a configuration memory window at segment D000.

2.2.2.3 Example 3 The Enabler will configure the IOP-241 in socket 1 with a base address of 340H and IRQ 10 using a configuration memory window at segment D000. Note that the parameter order is not significant. 2.2.2.4 Example 4 The Enabler will configure the IOP-241 in socket 0 with a base address of 300H and IRQ 3 using a configuration memory window at segment D800. -
Page 19: After Completing Configuration
2.2.3.3 Card and Socket Services Software In order to use the IOP-241 Enabler for DOS, the system MUST NOT be configured with Card and Socket Services software. If Card and Socket Services software is installed, the IOP-241 Enabler may interfere with its operation and with the device(s) it controls. For systems configured with Card and Socket Services, the IOP-241 Client Driver is the recommended method of configuration. -
Page 20: Windows 95/98® Installation
3. Windows 95/98® Installation To allow easy configuration of the IOP-241, a Windows 95/98 "INF" configuration file has been written for the hardware, (DAQPCARD.INF). Installing the IOP-241 Under Windows 95/98 1. Insert the IOP-241 into any available PC Card socket. -
Page 21: Changing Resource Settings With Device Manager
3. Open the Properties dialog box for the IOP-241, then click the Resources tab to view the Input/Output Range and Interrupt Request resource allocations, (see Figure 3-1). 4. To access the IOP-241, use these system resources allocated by Windows 95/98 or see Changing Resource Settings with Device Manager. -
Page 22: After Completing Configuration
Do not select a resource that causes a conflict with any other installed hardware. 7. Repeat the above steps to modify all of the resources allocated to the IOP-241. Once satisfied with the settings make a note of the new settings and click the OK button to accept. -

I/O channel to a TTL high voltage level. Upon reset of the IOP-241, the three data port control registers are all latched with a value of FFh. This forces all 24 open-collector output drivers 'off' upon a system power-up or upon an IOP-241 card insertion. -
Page 24: Port C Interrupt Description
In addition to the eight Port C interrupt sources, an additional external interrupt source is provided in the IOP-241. This external interrupt source is accessed through Pin 29 of the external connector. The external interrupt source permits the IOP-241 to be operated with 24-bit input/output and one separate interrupt source. -
Page 25: Register Descriptions
5. Register Descriptions The program registers of the IOP-241 occupy eight adjacent bytes of I/O address space. These registers must be programmed to control the operation of the IOP-241. The table below lists the program registers along with their offsets relative to the I/O space base address at which... -

Page 31: Programming Example
5.10 Programming Example The following C program segment demonstrates how to program an IOP-241 located at I/O base address 300h. Port A will be programmed as output, and 55h will be latched at Port A. Port B will be configured with it's upper 3 bits as output and it's lower five bits as input. The upper three bits will be latched with 010b. -
