Allen-Bradley DH+ Driver Help

Description of the parameters are as follows:

l Board Type: Select "PKTX" or " PKTX-D" from the drop-down menu, depending on which card is being

used.

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

l Station Address: This is the device's unique Node ID: 0-77 octal for DH+ and 0-31 decimal for DH-485.

Users must make sure that this value does not conflict with any other Node ID on the network.

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

network, the baud rates 115K and 230K under may not be supported by the card or device. For more

information, check the card and device vendor's specifications. The available baud rates for the DH-485

network are 300, 600, 1.2K, 2.4K, 4.8K, 9.6K and 19.2K. The selected baud rate should match the device

configuration.

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

instances on the computer. If the card being installed is the first PKTX/PKTX-D, the PCI Card Instance

should be 0. The PCI Card Instance for the next PKTX/PKTX-D card will be 1, and so forth. On Windows

NT, however, PKTX and PKTX-D cards are treated as two different types of cards. Thus, if two cards are

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. Up to 4 card instances are

allowed at a time. Thus, the maximum PCI Card Instances available for selection is 3.

l PKTX Channel: This number depends on the number of channels on the PKTX Card. If a PKTX card is

being used, there would only be one channel. If a PKTX-D card is being used, there would be two different

channels. When using the PKTX-D card, select the channel (1 for PKTX Channel 1A and 2 for PKTX

Channel 2) that will be used for the device.
