E2100 Jumper and Switch Settings
HELP: Board View Hardware Tables
The E2100 DNI card has the following jumpers, switches, and remote boot proms.
Setting The Board Select Jumper
This jumper allows you to set the I/O (Input/Output) base address that identifies the DNI Card to the PC. The I/O address is a hexidecimal field that distinguishes the DNI Card from other cards in the PC. The two shunts are supplied with the jumper in the event you want to use the 220H address setting.
Figure 1. Setting the I/O Base Address
Please Note: There may be different numbering schemes used in the manual. When using this illustration or text to set your jumpers, hold the DNI card so that text on the printed circuit board is readable. JP1 is comprised of two components, vertically mounted and labeled on the bottom from left to right, 2 and 1 respectively. The shunts will also mount vertically to connect the top and bottom pins of each component.
Select the Base I/O address by placing the shunts on JP1 as follows:
Remove the shunts so you can easily see the markings on the printed circuit board.
Select I/O 380 by not shunting any two pins (see note below and the illustration above).
Select I/O 300 by using one shunt vertically between the two right most pins (component 1).
Select I/O 280 by using one shunt vertically between the two left most pins (component 2).
Select I/O 220 by using both shunts vertically between both sets of pins (components 1 and 2).
Note: To avoid losing shunts, we recommend that unused shunts should be allowed to hang off one unused pin (but not between any two pins), as in the case of the default setting, I/O Base Address 380.
Setting the Boot Prom Jumper, JP2
Note: This jumper should be set ONLY if the Boot Prom is resident on the board. We recommend you follow the E21-BP-IPX Remote Boot Prom Installation Instructions, or the E21-BP-RPL Remote Boot Prom Installation Instructions before setting either JP1 or JP2 when a boot prom is being used.
Figure 2. Setting the I/O Base Address
Select ROM Address C000:0 by using both shunts over pins 1 and 2, and pins 3 and 4.
Select ROM Address D000:0 by using one shunt over pins 3 and 4.
Select ROM Address E000:0 by using one shunt over pins 1 and 2.
Select no shunts when there is no boot prom installed.
