Applications and Programming Information
MOTOROLA Introduction and Configuration 1-7
When using the parallel port version of the BDM cable, the BDM pod should be powered with a 2 - 5 V
negative center contact power supply or the SARD should be powered by a power supply through J106. A
9 V battery is not capable of sourcing the current required by the parallel BDM pod during programming
and debug.
1.4 Applications and Programming Information
1.4.1 Accelerometer Application Demo
The SARD comes pre-programmed with the accelerometer demo software. Consult the “Accelerometer
Demonstration Quick Start Guide”, document number AN2762/D for installation and startup instructions.
The receiver is connected to a PC COM port via an RS232 cable. The 9 V battery needs to be installed on
the battery terminals or a power supply must be connected to J106 and the on/off switch turned on. Start
the accelerometer GUI software, available from our website, and choose the COM port you are using in the
dialog box. Install the 9 V battery on the transmitter and turn it on. On the PC screen you can select various
ways to display the accelerometer data. One popular way is the cursor mode where you can watch the
cursor position move as the transmitter is moved.
1.4.2 Programming the SARD (User Defined Software)
A BDM programmer is used to load the MCU flash memory. Alternatively, the Embedded Bootloader
software, described in the, Embedded Bootloader User’s Guide, document number MC13192FLUG/D,
can be installed and the SARD can be programmed through the RS-232 port.
