Setting Up the Handler Interface Board

This section describes how to connect pull-up resistors to enable the output signals, and how to
set the dip switch to select voltage levels for the input signals. These procedures must be done
before using the handler interface.
Caution
SUSCEPTIBLE TO DAMAGE FROM ESD.
Perform the following procedures only at a static-safe workstation and wear a
grounding strap.
Caution
Be careful not to short the circuit when performing the following procedures.
For example:
Solder cleanly and carefully.
Guard against hair or dust getting on the circuit.
Do not damage the boards, wires, or parts on the board.

Tools and Fasteners

The 4349B mechanical components are secured using metric threaded fasteners. Many
fasteners in the 4349B may appear to be Phillips type, but they are Pozidrive type fasteners.
To avoid damaging them, use only Pozidrive screwdrivers to remove or tighten pozidrive type
fasteners.

Procedure

1. Disconnect the power cable from the 4349B and allow enough time (10 minutes) for the
internal capacitors to discharge.
Warning
Dangerous energy and voltage levels exist within the 4349B when it is in
operation and just after it is powered down. Allow 10 minutes for the
4349B's internal capacitors to discharge before starting to work on it.
2. Remove the two screws which fasten the cover to the chassis rear panel.
3. Slide the cover toward the rear while holding the front panel bezel.
