Allen-Bradley DH+/DH-485 Device Driver Help
Note: In our board type selection, we will be choosing KTX (D) for both the KTX and KTX-D card.
Network Type
This driver supports both the DH+ and DH-485 network types. Each of the Allen-Bradley cards (KT, KTX, KTX-D, PKTX,
PKTX-D and PCMK/B) support both DH+ and DH-485 networks. SST cards (5136-SD-ISA and 5136-SD-PCI) support
only the DH+ network.
Station address
This is a unique node ID (0-77 octal for DH+ and 0-31 decimal for DH-485) of your device. You must make sure that
this ID doesn't conflict with any other node ID on the network.
Baud Rate
There are several different baud rates that each of the card types support. The Allen-Bradley cards support 57.6K,
115K and 230K for the DH+ network. For the DH-485 Network, the Allen-Bradley cards support 300, 600, 1.2K, 2.4K,
4.8K, 9.6K and 19.2K. The SST cards as mentioned above support only the DH+ network, and the supported baud
rates are 57.6K, 115K and 230K.
Memory Address
The ISA cards (KT, KTX, KTX-D and 5136-SD-ISA) require the user to manually set the memory address on the card.
For more information on memory address setup, please refer to the appropriate catalogue. See Also: KTX (D)
channel setup and5136-SD-ISA channel set up.
Interrupt
Each of the card types support interrupts. The PCI card types automatically set up the interrupts for your card. The ISA
cards (KT, KTX, KTX-D and 5136-SD-ISA) require you to select a unique interrupt level from the drop down menu next
to the Interrupt label. Make sure it matches what you have selected while performing hardware configuration. If
you don't want to use interrupts, select None.
I/O Port Address
In addition to configuring the memory address on your 5136-SD-ISA card, you must also select a port address
manually. Refer to the link below for more information.
Please configure the I/O port and jumper settings on your SST ISA card. If the link does not provide your
answer, please refer to the appropriate SST catalogue that came with your card.
PCI Card Instance
This number depends on the number of similar PCI Card Instances on your computer. If the card is the first PCI you are
installing, your PCI Card Instance should be 0. If the next PCI card you are installing is from the same vendor, the PCI
Card Instance for that card should be 1, etc. If, however, the next PCI card is from a different vendor and is the first
card of that type you are installing, the PCI Card Instance should be 0. We currently allow up to 4 card instances at a
time. Hence, the maximum PCI Card Instance you can select is 3.
PKTX Channel ID
PKTX cards come in two forms. It can either be a single channel (PKTX) or it can be a dual channel card (PKTX-D).
Therefore, when a PKTX/PKTX-D card is used, the driver needs to know what channel it should be using. Selecting one
of the channels that shows up in the PKTX Channel ID drop down menu helps the driver know which channel to talk to.
If you are using the PKTX-D card, select the channel (1 for PKTX Channel 1A and 2 for PKTX Channel 2) that you want
to use for your device.
Channel Setup for the Allen Bradley- 1784 KT card
Before setting the channel properties, you must have the KT card configured for a unique memory address and
interrupt on the hardware. The selected address and interrupt should be noted, as these parameters will be used for
setting up the channel properties in the server.
Step 1: Configuration
Refer to your KT documents for Hardware configurations (Memory and Interrupt setup).
Step 2: Installation
Install the KT card on an available ISA slot and connect to the appropriate network.
Step 3: Channel Properties Setup for the KT Card.
