Note: Data Highway-485 (DH-485) is only applicable to Allen-Bradley cards.

Channel Properties

Board Type

This parameter specifies the board type. This driver supports 8 different board types by Allen-Bradley and SST.

The Allen-Bradley types include KT, KTX, KTX-D, PKTX, PKTX-D and PCMK/B. The SST board types include 5136-

SD-ISA and 5136-SD-PCI.

Note: Both the KTX and KTX-D card examples will select KTX (D) as the board type.

Network Type

This parameter specifies the network type. This driver supports both DH+ and DH-485: each of the Allen-Bradley

cards support the DH+ and DH-485 networks, but SST cards only support the DH+ network.

Station Address

This parameter specifies the device's unique Node ID: 0-77 octal for DH+ and 0-31 decimal for DH-485. Users

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

Baud Rate

This parameter specifies the baud rate. Each of the card types support several different baud rates. For the DH+

network, Allen-Bradley cards support 57.6K, 115K and 230K. For the DH-485 Network, Allen-Bradley cards

support 300, 600, 1.2K, 2.4K, 4.8K, 9.6K and 19.2K. Since SST cards only support the DH+ network, the

supported baud rates are 57.6K, 115K and 230K.

Memory Address

This parameter specifies the card's memory address. The ISA cards (KT, KTX, KTX-D and 5136-SD-ISA) require

that the user manually sets the memory address on the card. For more information, refer to the appropriate

catalog, Channel Setup for the Allen Bradley- 1784 KTX/KTX-D Card and Channel Setup for 5136-

SD-ISA Card.

Interrupt

This parameter specifies interrupts, which are supported by each card type. The PCI card types automatically set

up the interrupts, whereas the ISA cards (KT, KTX, KTX-D and 5136-SD-ISA) require that a unique interrupt

level be selected. This setting must match the selection chosen during hardware configuration. To not use

interrupts, select "None." For more information, refer to Hardware Configuration of Memory and Interrupt

on 1784 KTXD Card.

I/O Port Address

This parameter specifies the port address, which must be selected manually (in addition to configuring the

memory address on the 5136-SD-ISA card). For more information, refer to Hardware Configuration of the

5136-SD-ISA (SST) Card and the appropriate SST catalog.

PCI Card Instance

This value depends on the number of similar PCI Card Instances on the computer. If the card is the first PCI being

installed, then the PCI Card Instance should be 0. If the next PCI card being installed is from the same vendor,

then the PCI Card Instance for that card should be 1 (and so forth). If the next PCI card is from a different vendor

and is the first card of that type being installed, then the PCI Card Instance should be 0. Up to 4 card instances at

a time are allowed. The maximum PCI Card Instance that can be selected is 3.
