Block Request Size
Request size refers to the number of bytes that may be requested from a device at one time. You can refine the
performance of this driver by configuring the request size to one of the following settings: 32, 64, 128 and 230 bytes.
The default value is 230 bytes.

Hardware Configuration of the 5136-SD-ISA (SST) card
Note: You must ground yourself by touching a grounded object (such as the chassis of your computer) before handling
the card.
I/O Port Configuration: The 5136-SD-ISA card uses I/O ports (the default address is 250). If another device is
already using address 250, DIP switches are available on the card to configure a unique I/O port address.
The I/O space required is 8 bytes. Thus, the setting of 250 will select ports 250-257. Below are some of the options of
the DIP switch settings that you have for selecting the Port addresses. If you need to select some other address, refer
to the 5136-SD-ISA User's Guide that came with your SST card.

Transmit Jumper: The 5136-SD-ISA card uses jumper JB2 to enable or disable transmission from the card. Position
"DISA" disables transmission and position "ENB" enables it. The jumper must be set to "ENB" to enable message
transmission through the DH+ network.
You should now be all set to install the card on an ISA slot in your computer.
