Installation instructions:
Important: Components are static sensitive. Take ESD precautions - use a wrist
grounding strap.
1. Disconnect all cables from the Model 2002.
2. For the installation of an option board you must have access to both the front and rear of
the Model 2002. Remove the instrument from its mounting panel if necessary.
3. Remove the option blanking panel from above the power inlet module on the rear panel.
Replace it with the RS-232 board connector panel supplied in your upgrade kit. Install the
panel so that the wider edge is to the bottom of the instrument.
4. Un-snap the bezel from the front of the case. Remove the four screws from the front panel,
then carefully remove the front panel.
5. Insert the RS-232 option board (component side down) into the top slot of the Model 2002
case and attach the board to the back panelusing the supplied jack screws.
6. Connect the ribbon cable of the option board to the I/O port (P1) on the main PC board.
The brown wire of the cable denotes pin one and should be installed toward the front of the
case.
7. Reattach the front panel (take care not to kink the ribbon cable). Snap the bezel onto the
front of the case.
Note: Upon examining the RS-232 option board you will find several jumper
settings. These jumpers allow the board to be configured for either RS-232 or RS-
485 communications. These jumpers are preset at the factory as per customer order.
To change these settings please consult the factory.
