Unpack and inspect
Make sure to handle the KTTI-RS232 card carefully. Always grasp the card by the side edges.
Do not touch board surfaces, components, or areas adjacent to electrical contacts.
Contamination from foreign materials such as dirt, dust, and body oils can substantially
degrade card performance.
To unpack and inspect your card:
1. Inspect the box for damage.
2. Open the box.
3. Remove the card and inspect for any obvious signs of physical damage.
4. Report any damage to the shipping agent immediately.
Installation
Slot covers must be installed on unused slots to prevent personal contact with high-voltage
circuits. Failure to recognize and observe standard safety precautions could result in
personal injury or death due to electric shock.
To install the communications card:
1. Turn the instrument off and disconnect the power line cord and any other cables connected to the
rear panel.
2. Position the instrument so that you are facing the rear panel.
3. Remove the slot cover plate from the slot on the back of the instrument. Retain the plate and
screws for future use.
4. Align the card with the connector toward the inside edge of the slot and slide the card into the
chassis. For the last ¼ inch, press in firmly to mate the card to the connector.
5. On each side of the card, there is a spring-loaded mounting screw. Tighten these two screws,
either by hand or with a Phillips-head screwdriver, to secure the card in the case. Do not
overtighten.
