OEM BS2sx - Rev A

1. The two lowest profile components on the board are the 4.7K

2. The next lowest profile component on the board is the 20-pin

3. Next, find the two 0.1 uF ceramic capacitors. Like, the resistors, it doesn’t matter

4. The next component to look for is a small capacitor like C2 and C3 except that this one is a

5. Next, find the resistor networks. A resistor network looks like

6. The IC sockets are next in line. Nearly all ICs have a ‘Pin 1’

Ohm resistors. These resistors should have color bands around

them which signify their value. The color band pattern should be: Yellow, Violet, Red, and

Gold. Resistors are polarity insensitive, which means that it doesn’t matter which end goes

where. Install the resistors where designated by ‘R1’ and ‘R2’.

right angle strip header. It may seem ambigious as to which side

is inserted into the pcb. The side with the angle should be

inserted into the pcb as shown in the drawing to the right. Install

the strip header where designated by ‘X1’.

which way these are installed. Install the two capacitors where designated by ‘C2’

and ‘C3’.

5pF capacitor and is marked with a ‘5’. Install this capacitor where designated by ‘C4’.

a comb for a ‘Barbie Doll’. On the resistor network (Rnet),

there is a dot printed near one end to signify at which end Pin

1 is located. Find Pin 1 on the Rnet and correlate it to the

square pad on the PCB

designator. Install the Rnets where designated by ‘RN1’ and ‘RN2’.

marker that denotes the location of Pin 1. It is important to

install chips with the proper orientation since, more often

than not, installing a chip backwards will result in damage to

the chip and/or surrounding circuitry. For the IC sockets that

you will be installing, there is a notch on the edge of one of

the short sides. This notch denotes the ‘top’ of the chip.

When oriented properly, Pin 1 is the top-left pin as depicted

in the drawing to the right. Install both the 28-Pin and the 8-

Pin DIP sockets into U1 and U2 respectively.

This document is a guide that will aid you in the assembly of your

OEM-BS2sx. It is assumed that you have the proper equipment,

and possess the skills necessary to safely assemble electronic

components.

Generally, it is best to start with the lower profile components, and

then work your way to the tallest components. This is often true

because, in tight places, lower profile components are more

difficult to get to with taller components in the way.
