Hardware Configuration of the 5136-SD-ISA (SST) Card
Important: Users must ground themselves by touching a grounded object (such as the chassis of the
computer) before handling the card.
I/O Port Configuration
The 5136-SD-ISA card uses I/O ports. The default address is 250. DIP switches are available on the card to
configure a unique I/O port address in case another device is already using that address. The I/O space required
is 8 bytes. Thus, the setting of 250 will select ports 250-257.
The table below displays some of the DIP switch settings options that may be selected for the port addresses. If
another address is required, refer to the SST card's 5136-SD-ISA User's Guide.

Transmit Jumper
The 5136-SD-ISA card uses jumper JB2 to enable or disable transmission from the card. Position "DISA" disables
transmission whereas position "ENB" enables it. The jumper must be set to "ENB" to enable message
transmission through the DH+ network.
Note: Users should now be all ready to install the card on an ISA slot in the computer.
Hardware Configuration of Memory and Interrupt on 1784 KTXD card
Users must select a unique memory address and Interrupt Request Level (IRQ). The valid memory address range
is C800-D700. The valid interrupt levels are 3, 4, 5 and 7. To make sure that the value chosen for the interrupt is
unique, users should check the Device Manager. For more information, refer to Check Device Manager.
Memory Configuration
The Allen Bradley 1784-KTX (D) card has two channels for communication. When planning to use channel 1,
users must turn the knobs (sw3 and sw4) under Channel 1 to reflect the selected memory address. For example,
if address D000 is chosen, then the sw3 should point to "D" and sw4 should point to "0." Similarly, when
planning to use channel 2, users must turn the knobs (sw1 and sw2) to reflect the selected memory address. For
more information, refer to Cable Connections.
Interrupt Configuration
When using interrupts, users should choose an interrupt level. As mentioned above, valid interrupt levels are 3,
4, 5 and 7. The KTX (D) card comes with two jumpers. Each jumper is used for selecting the interrupt level for
each of the channels. The jumper should be placed corresponding to the chosen channel number, horizontally
across the two pins next to the selected interrupt level. For example, if using channel 1 with interrupt level 3
