DIGITAL INPUT/OUTPUT CARD IOD-144 USER MANUAL
1-1
INSTALLING THE CARD
Before installing the card carefully read the ADDRESS SELECTION and OPTION
SELECTION Sections of this manual and configure the card according to your require-
ments. Use the special software program called SETUP.EXE provided on diskette with
the card. It supplies visual aids to configure all areas of the board.
Be especially careful with address selection. If the addresses of two installed functions
overlap, you will experience unpredictable computer behavior. If unsure what locations
are available, you can use the FINDBASE program provided on our diskette to locate
blocks of available addresses.
To install the card:
1. Remove power from the computer.
2. Remove the computer cover.
3. Remove blank I/O backplate.
4. Install jumpers for selected options. See OPTION SELECTION section of
this manual.
5. Select the base address on the card. See ADDRESS SELECTION
section of this manual.
6. Loosen the nuts on the strain relief bar and swing top end free.
7. Install the card in an I/O expansion slot. If convenient, select a slot which
is adjacent to a vacant slot because this will make cable installation
easier.
8. Thread the I/O cables, one by one through the cutout in the mounting
bracket and plug them into the headers.
9. Smooth the cables as close as practicable to the card and while holding
them close to the card surface, swing the strain relief bar into position
and tighten nuts.
10. Inspect for proper fit of the card and cables and tighten screws. Make
sure that the card mounting bracket is properly screwed into place and
that there is a positive chassis ground.
11. Replace the computer cover.
Input/Output connections are via six 50-pin headers on the card. A blank mounting
bracket is provided with units that are marked for CE (European) Certification and, for
these units, CE-certifiable cable and break-out methodology (cables connected to
ground at the aperture, shielded twisted pair wiring, etc.) must be used.
