Chapter 1 Introducing the 1784-PKTx Communication Interface Cards Your 1784-PKTx communication interface card (cat. nos. 1784-PKTX, 1784-PKTXD, and 1784-PKTS) is a PCI (Peripheral Component Interconnect/Interface) card that must be inserted into a PCI bus slot. Table 1.
1-2 Introducing the 1784-PKTx Communication Interface Cards Compatibility Table 1.3 shows the computer models with which the 1784-PKTx has been verified to work. Table 1.
Introducing the 1784-PKTx Communication Interface Cards 1-3 The 1784-PKTx performs data transmission, management, and local network diagnostics. The interface to the host processor is through a boardresident dual-port memory. Rockwell Automation interface software (including RSLinx) manages data transmission and reception through dual-port memory. The PCI BIOS on your computer automatically assigns the PKTx card’s IRQ and base memory address (one for each channel).
1-4 Introducing the 1784-PKTx Communication Interface Cards Compliance to European Union Directives If this product has the CE mark, it is approved for installation within the European Union and EEA regions. This equipment is classified as open equipment and must be mounted in an enclosure during operation to provide safety protection. It has been designed and tested to meet the following directives.
Chapter 2 Configuring the PKTx Hardware Introduction The 1784-PKTx card is a PCI bus card, compliant with the PCI Bus Specification Revision 2.1. This card was developed with Plug and Play functionality, as defined in Revision 1.0A of the Plug and Play BIOS Specification. Because of this, PKTx cards do not require the use of switches or jumpers to configure their specific interrupt request levels (IRQ) and base memory address values.
2-2 Configuring the PKTx Hardware The Base Memory Jumper (JP2) Card ID Jumper (JP3) 40021 Figure 2-1 Overview of the jumpers on the PKTx card Base Memory Address Restriction Although the assignment of the IRQ and base memory address values is automatic, and does not require user intervention, there is one jumper on the PKTx card that is used to restrict the range of values that can be assigned to the base memory address by the PCI BIOS.
Configuring the PKTx Hardware 2-3 Setting a Base Memory Address Jumper The host computer and the PKTx card exchange data via a dual-port interface. The dual-port requires 4 Kbytes of memory. This 4 Kbyte block of memory begins at the base memory address assigned to the card by the PCI BIOS when the computer is started. Under MS-DOS, Windows 3.1 and Windows for Workgroups, the base memory address of PC cards should fall within the range of 0 and 1 Megabyte of PC memory.
2-4 Configuring the PKTx Hardware When looking directly at the 1784-PKTx card, the Base Memory Address jumper looks like: 32BIT This is a jumper that is not covered. 1MEG 32BIT This is a jumper that has the 32bit position for Windows 95 covered. 1MEG 40022 Establishing Multiple PKTx Cards It is possible to have more than one PKTx card within your system. However, you can only have up to four cards functioning at the same time.
Configuring the PKTx Hardware 2-5 Planning Jumper Settings for Multiple Cards Located on each PKTx card are a set of jumpers with markings which indicate how each jumper can be set. These jumpers are identified as JP3. It is important to coordinate the setting of these jumpers so that each card can be recognized by the system. The example below shows possible combinations of jumper settings that may be used if you have a total of four cards. Below is an example of a covered jumper for card ID 2.

Chapter 3 Installing the Card Inside the Computer You’ve set the jumpers; now you’re ready to place the PKTx card inside your computer. Before You Begin Consider these points before you begin: • Do I know everything I need to know to accomplish my task? • Do I have the proper tools at hand? • Do I understand where I can and cannot put this card? ! ATTENTION: Before you can install the PKTx card, you need to verify that the appropriate jumpers have been set.
3-2 Installing the Card Inside the Computer Necessary Tools You need one of these tools to remove the cover from your central processing unit (CPU): • Phillips-head screwdriver • flat-head screwdriver Accessing the Computer’s PCI Bus Slots To install the PKTx card, you must have access to the computer’s PCI bus. Refer to your computer’s hardware manual for instructions about how to: 1. Shut down the computer. 2. Turn off power to the computer.
Installing the Card Inside the Computer 3-3 Inserting the Card To insert the card inside the computer: 1. Follow the card handling instructions on page P-3. 2. Make sure you have set correctly the jumpers on the card. (See chapter 2.) 3. Turn off power to the computer. Important: If you disconnect the ac power from the computer, you lose the chassis ground. Electrostatic damage (ESD) protection is lost. 4. Loosen the expansion slot screw and remove the outside retaining bracket (ORB). 5.
3-4 Installing the Card Inside the Computer The Windows 95 and the 1784-PKTx Card To use the PKTx card with Windows 95, you need an appropriate plug and play driver. RSLinx contains the appropriate DH+/DH-485 driver for the 1784-PKTx card. Install RSLinx or a custom software driver before you attempt to use the PKTx card. To verify that your PKTx card is using the appropriate driver, use the Device Manager within Windows 95.

Appendix A Running Diagnostics What’s in This Appendix This appendix contains instructions for running the PKTXD utility and KTx diagnostics. The PKTXD utility reports the IRQ and the base memory address (one for each channel) of a PKTx card. The KTx diagnostics check PKTx’s network and host communications, interrupts, and memory access. Important: The 1784-PKTS card will not run the dual-port tests, i.e., it will attempt to run and fail.
A-2 Running Diagnostics 4. Call Allen-Bradley Automation Group Technical Support at (216) 646-6800. Instructions are printed at the beginning of the log file. Obtaining the Base Memory Address and the Interrupt Request Before you can begin to use the diagnostics, you need to record the base memory addresses and the interrupt request (IRQ) of the card(s) you wish to test.
