How the 1784 KT Operates
The 1784-KT allows you to: directly connect to: - PLC-2 processors - PLC-3 processors communicate with nodes on Data Highway Plus networks (including PLC-5 and PLC-5/250 processors) communicate with SLCTM processors (requires 1785-KA5 bridge) The 1784-KT performs data transmission, management, and local Data Highway Plus diagnostics. The interface to the host processor is through a board-resident dual-port memory that passes preformatted Data Highway Plus packets. When the host powers up and downloads module code, it runs diagnostics to verify the 1784-KT module's operation. Allen-Bradley interface software (including 6001-F1E, 6200, Interchange, Advisor PC, and ControlView) manages data transmission and reception through the board-resident dual-port memory.

Handling the 1784 KT Module
The 1784-KT utilizes CMOS technology, which is highly sensitive to Electro Static Discharge (ESD). ESD may be present whenever you are handling the 1784-KT. Handling the 1784-KT without any ESD protection can cause internal circuit damage that may not be apparent during installation or initial use. A grounding wrist strap has been shipped with the 1784-KT to be worn during the installation procedure. Instructions for use of the strap are found on the back of its package. ATTENTION: The following is a list of precautions to guard against ESD damage: 1. Before handling the module, be sure to wear the provided static strap and touch a grounded object to discharge any built-up static charge. When selecting your memory and interrupt options, avoid touching other components on the 1784-KT. Avoid touching the back plane connector or interface connector pins located on the 1784-KT. If the module is not in use, store the 1784-KT in the static bag that the module was shipped in.

1784 KT Configuration Information
Important: Do not change the (factory set) configuration settings until you have read this section. The 1784-KT comes with preset memory location (D400) and no interrupt. This may not be appropriate for your application. See the section "Installing the 1784-KT into a Computer", which begins on page 6, for information on memory locations and interrupt settings.
ATTENTION: When selecting configuration settings, check for conflicts with other interface cards and system memory. If there is a conflict, the system will not operate properly.

Installing the 1784 KT into a Computer
The following steps outline how to install the 1784-KT into a terminal, workstation or computer. Refer to the terminal's, workstation's or computer's hardware user manual for further assistance. 1. 2. Turn off the computer and disconnect the ac power cord. Remove all covers necessary to gain access to the computer's expansion slot area. The industrial terminals may have retainer brackets. Consult the user manual for access procedures.
ATTENTION: If you are not wearing the grounding wrist strap, put it on at this time.
3.
Remove the expansion slot bracket that covers the computer I/O opening. Remove the 1784-KT from the static bag. Verify the configuration settings for your system. Use the worksheets that begin on page 15 for assistance.
4. 5.
Important: If another card is already using your desired switch settings, you will have to change the card's switch settings to an open memory location. If you are using the default settings, go to step 10. If you are not using the default settings, go to step 6. 6. Select a memory location. Table A shows the recommended memory locations for Allen-Bradley terminals, workstations and computers. Table B shows all the available memory locations and switch settings for the card.

System Memory and Interrupts
Information is passed between the computer system and the 1784-KT through 2 Kbytes of memory located in the interface module. This 2 Kbyte memory is memory mapped into an open memory location in your computer system. The definition of "open" is a location that has not been configured for another optional interface card or system. The 1784-KT address decoding allocates a 16 Kbyte memory location. So, when selecting an open memory location, make sure there is a 16 Kbyte block. Also, the definition of open applies to hardware system interrupts. Depending on the interface card you have installed into your computer, only a few select interrupts may be open for the 1784-KT. Let's say the targeted computer for installing a 1784-KT is an IBM PC-AT with the following options:
640 K System Memory EGA Card Color Monitor Diskette Drive Hard Drive Serial Port Card (Configured for port 1) 00000:0000 09000:FFFF 0A000:0000 0A000:FFFF 0B000:0000 0B000:FFFF 3F0 3F7 1F0 1FF 2F8 2FF IRQ 6 IRQ 14 IRQ 4
The memory map for this system would be what is documented in the "System Memory Allocation Worksheet" (see page 15) for the IBM PC-AT. Open memory for a 1784-KT would be from 0B800:0000 to 0DF00:0FFF. By using the memory default setting, the 1784-KT would fit into this open memory at locations 0D400:0000 to 0D700:0FFF. The 1784-KT supports four interrupts: IRQ3, IRQ4, IRQ5, and IRQ7. Refer to the "Hardware Interrupt Allocation Worksheet" (page 17) for the IBM PC-AT for possible open interrupts. Only IRQ4 is used for the serial port card configured for port 1. The 1784-KT uses the "no interrupt" setting as the default. Use the following worksheets to help manage your system's memory, I/O, and interrupt assignments. The IBM PC-AT and IBM PC-XT system assignments have been chosen as a reference. These IBM assignments are available in their respective IBM Technical Manuals and are subject to change by IBM. Important: The 1784-KT does not require a system I/O address. The 1784-KT only uses addressable memory and an interrupt. The I/O map is provided so that you can document your entire computer system. To use the worksheets, enter your computer's memory, I/O, and interrupt assignments in the column labeled "Your System" .
