Directed Resistor Interface Pack

N451M 2-03

The Directed Resistor Interface Pack is an assortment of resistors

used to interface with most of today's multiplexed circuits.

When using the Directed Resistor Interface Pack, some circuits may

require a different resistance value than the resistors supplied. If

necessary, different resistance values may be obtained by combin-

ing the resistors in a parallel or series connection, both of which

will provide different values.

For example, if the 620 OHM resistor and the 660 OHM resistor are

wired in parallel, the value is 320 OHMS. The same resistors wired

in a series configuration will produce a value of 1280 OHMS. This

allows greater flexibility with more values to use while interfacing

with the multiplexed systems of today's vehicles.

Series Connection

In a series connection, the end value is the sum of Resistor 1 (R1)

and Resistor 2 (R2). I.e., R1 + R2 = R3.

Parallel Connection

In a parallel connection, the end value is determined by Resistor 1

(R1) multiplied by Resistor 2 (R2). That total is then divided by the

sum of R1 and R2. I.e., (R1 x R2)

= R3

(R1 + R2)
