Allen-Bradley DH+/DH-485 Device Driver Help



Select the Board Type: Select "PKTX" or " PKTX-D" as the "Board Type" (depending on whether you are using

PKTX or PKTX-D card) from the drop down menu next to the "Board Type" label.



Select the Network type: This driver currently supports DH+ and DH-485 networks for PKTX/PKTX-D cards.



Enter the 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.



Select the Baud Rate: The available baud rates for the DH+ network are 57.6K, 115K and 230K.The Baud rates

115K and 230K under the DH+ network may not be supported by the card you are using or the device you are

talking to. Check the card and device vendor specifications. The available baud rates for the DH-485 network are

300, 600, 1.2K, 2.4K, 4.8K, 9.6K, 19.2K. Select the one that matches your device configuration.



PCI Card Instance: On Windows XP/2000, this number depends on the number of PKTX/PKTX-D card instances

on your computer. If the card you are installing is the first PKTX/PKTX-D, your PCI Card Instance should be 0.

The PCI Card Instance for the next PKTX/PKTX-D card will be 1 etc. On Windows NT however, PKTX and PKTX-D

cards are treated as two different types of cards. Hence, if you have two cards installed (one PKTX and one

PKTX-D), the PCI Card Instance for both cards will be 0. The PCI Card Instance for the next PKTX will be 1 and

for the next PKTX-D card will also be 1 etc. We currently allow up to 4 card instances altogether at a time.

Hence, the maximum PCI Card Instance you can select is 3.



PKTX Channel: This number depends on the number of channels on your PKTX Card. If you are using a PKTX

card, you would have only one channel. However, if you are using PKTX-D, you would have two different

channels. If you are using the PKTX-D card, please select the channel (1 for PKTX Channel 1A and 2 for PKTX

Channel 2) that you would want to use for your device.
