USER MANUAL

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.
