• OVERBAR is used to indicate a signal that is active when pulled low: for example, RESET.

• Logic level one is a voltage that corresponds to Boolean true (1) state.

• Logic level zero is a voltage that corresponds to Boolean false (0) state.

• To set a bit or bits means to establish logic level one.

• To clear a bit or bits means to establish logic level zero.

• A signal is an electronic construct whose state conveys or changes in state convey information.

• A pin is an external physical connection. The same pin can be used to connect a number of signals.

• Asserted means that a discrete signal is in active logic state.

— Active low signals change from logic level one to logic level zero.

— Active high signals change from logic level zero to logic level one.

• Negated means that an asserted discrete signal changes logic state.

— Active low signals change from logic level zero to logic level one.

— Active high signals change from logic level one to logic level zero.

Table 1-1. Rev. 2 to Rev. 3 Board Differences

Item Description

D105 A Power on Reset LED (D105) was added.

C130 A 100pF capacitor (C130) was added an Reset switch for ESD protection.

RF Strip Lines (Receive) The RF strip lines for the receiver (W101 and W102) were changed. The Z0 120 ohm, 22.5 degree electrical length is equal to a physical length of 4.5mm. This optimizes receive sensitivity.

RF Strip Lines (Transmit) The RF strip lines for the transmitter (W103 and W104) were changed. The Z0 120ohm, 58 degree electrical length is equal to a physical length of 11.5mm. This optimizes RF output power.

L101 and C131 A filter (L101 and C131) was added on PA out to reduce 2nd and 3rd spurious harmonics.

IC109 and IC108 The LDO ICs 109 and IC108 were changed for output power. Higher current is needed to support a parallel BDM interface.

Figure 1-4. SARD Component Layout




1.3.3 RS232 Connector J102The RS232 port is J102, a DB9 connector. A standard straight-through DB9 serial cable can be used with a PC. The port follows the standard RS232 DCE DB9 convention as shown in Figure 1-5. The RS232 is normally used to connect the SARD to a PC. With an installed bootloader program such as the Sensor Applications Reference Design (SARD) Embedded Bootloader program, described in document number 802154EBRM, it can also be used to program the MCU.

Figure 1-5. DCE-DB9 Female Connector (Looking into the SARD Connector)

1.3.4 Power CapabilityThe SARD can be powered from a 9 V battery (6LR61) connected to the board-mounted battery terminals or a 9 V adapter connected to the DC connector. See Figure 1-4 for battery terminal and DC connector placement. If the accelerometers are not used, 2.0-3.4 V can be supplied on J103. In this configuration, the accelerometer outputs are indeterminate.

The 9 V adapter used for this product must be the PHIHONG type PSA-05R-090.

NOTEDo not use a Lithium battery.

1.3.5 LEDs and SwitchesD101 through D104 and Switches S101 through S104 are connected to I/O as shown on the SARD schematic in Figure 1-3 and in the SARD board layout in Figure 1-4. These are useful as indicators and control in applications. Connections to MCU ports are listed in Table 1-2. The on-off switch, S105 is labeled on the board.

1.3.6 Board Reset FunctionA hardware reset can be performed on the SARD in two ways:

• The Reset push button.

• The MCU resets the SARD as part of its startup sequence when power is applied and the On/Off switch is turned on.

In both cases, the reset sequence resets the MCU which, in turn, resets the MC13192.

1.3.7 MCU General Purpose Input/Output (GPIO)Figure 1-4 shows the MCU GPIO that can be interfaced with external hardware such as sensors. When using the on-board accelerometers, shunts must be installed at PTB0, PTB1, and PTB7, which corresponds to pins 1 and 2, 3 and 4, 11 and 12, of J105, to connect the accelerometer ICs to the MCU. For user defined applications, these shunts can be removed and other hardware attached to the GPIO pins.

1.3.8 BDM PortHeader J101 is a BDM port for use with a P&E BDM-Multilink cable which is available from Metrowerks. The BDM cable is used with CodeWarrior for the HCS08 to program the MCU flash memory as well as performing in-circuit debugging. See Figure 1-4 for the position of pin 1. The red lead of the BDM cable must align to pin 1 of J101.

When using the parallel port version of the BDM cable, the BDM pod should be powered with a 2 - 5V negative center contact power supply. A 9V 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 DemoThe SARD comes pre-programmed with the accelerometer demo software. See the Accelerometer Demonstration Quick Start Guide, (AN3230) for installation and startup instructions. The receiver is connected to a PC COM port via an RS232 cable. The 9V battery needs to be installed on the battery terminals 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 9V 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 Reference Manual, (802154EBRM), can be installed and the SARD can be programmed through the RS-232 port.
