Quick Start Guide
Step-by-Step Installation Instructions
In this quick start guide, you will learn how to set up the TWR-PXN20 module and run
the included demonstration software. For more detailed information, please see the
user manual found on the included DVD or at  freescale.com/TWR-PXN20 .
1
Connecting the
TWR-SER
3
Using the Serial
to USB Bridge
2
Insert the TWR-PXN20 and TWR-SER
modules into the primary and secondary
elevator module (as shown). The 
“primary” and “secondary” cards edges
for each module are indicated along the
card edges.
Powering Up the
TWR-PXN20
Connect the TWR-PXN20 module to a
computer or a wall charger using the
provided USB cable. Additionally, the 
The MC9S08JM60 serial to USB bridge 
solution provides an RS-232 equivalent
connection to the host computer through
the USB communications device class. 
When plugged in and powered, the USB 
connection will enumerate as a COM port
on the PC. This means any terminal utility
program may be used to receive serial
data from the USB port. To determine the 
COM port number for the connection, right
click on the My Computer icon and select
“Manage,” click Device Manager, find and
expand ports (COM and LPT).
USB connector on the primary elevator 
or OSJTAG connector can be used to
power up the module.

Installing the
Software Driver
When the cable is plugged in for the first
time, the Found New Hardware Wizard 
will start. Select the option Install from a
list or specific location (Advanced), then
