See DIGI International s website ( regarding the X-CTU software for configuring and testing XBee Wireless modules. 2.2 Hardware installation The Z232 can be connected to controller directly on to the controller s J2 header (PIO-UART mode) or connected to the controller s RS232 serial port via serial cable (RS232 mode). Hardware installation for the Z232 will vary based upon which controller board is used. Refer to the technical manual of the controller board for additional details.

It can be driven by an RS232 serial port or a PIO (5V or 3.3V) UART at 9600 baud. Compatible controllers include AE, EE, RE, i386e, 586E, or any board with a PIO-UART or an RS232 UART. 3.2 XBee-PRO Features The XBee-PRO OEM RF Modules are engineered to meet IEEE standards and support the unique needs of low-cost, low-power wireless sensor networks. The modules require minimal power and provide reliable delivery of data between devices. The modules operate within the ISM 2.4 GHz frequency band and are pin-for-pin compatible with each other. Features: 2.4GHz operational frequency Up to 300 (90m) range indoors Up to 1 mile (1600m) range outdoor line-of-sight. RF data rate of 250,000 bps 3.3V transmit peak current 3.3V receive peak current 3.3 Wireless Interface controllers can interface the Z232 either directly in PIO-UART to wireless mode or over an RS232 serial cable in RS232 to wireless mode. PIO-UARD to Wireless Mode In PIO-UART to wireless mode, the Z232 plugs directly on top of the controller at header J2. The controller communicates with the XBee wireless module over a 0-5V or 0-3.3V UART connection. Jumpers on the H1 2x3 header must be set to correctly in order to facilitate this mode (H1.1=H1.2, H1.3=H1.4). H1 Figure 3.1 H1 jumpers for PIO-UART to wireless mode 3-1

The controller communicates with the XBee wireless module over a RS232 serial connection. Jumpers on the H1 2x3 header must be set to correctly in order to facilitate this mode (H1.1=H1.3, H1.2=H1.4, H1.5=H1.6). Note that the serial cable must crossover in order to communicate properly.

10 Chapter 3: Hardware Power Supply The Z232 has an on-board 5V linear regulator by default. The linear regulator requires 9-12VDC input at the two pin terminal block T1. For applications requiring more flexibility in input voltage range, the Z232 supports an optional 5V switching regulator. The switching regulator can accept an input voltage range of 9 to 35VDC. In PIO-UART to wireless mode, the 5V regulator will supply power to the controller as well as the Z232. In RS232 to wireless mode, the Z232 and controller must be powered separately. 3-3

11 Error! Reference source not found.software Chapter 4: Software 4.1 Introduction By default, XBee /XBee-PRO RF Modules operate in Transparent Mode. When operating in this mode, the modules act as a serial line replacement - all UART data received through the DI pin is queued up for RF transmission. When RF data is received, the data is sent out the DO pin. While the modules can operate in other modes, configures and supports only the Transparent Mode. Information about addition features and operation modes can be found in the XBee/XBee-PRO OEM RF Modules Product Manual. ** See the XBee/XBee-PRO Product Manual for detailed information on using the modules. 4.2 X-CTU Configuration & Test Utility Software DIGI International, makers of the XBee and XBee-PRO wireless, provide a free configuration utility for use with their wireless modules. X-CTU is a Windows-based configuration utility designed to interact with the firmware files on DIGI s XBee modules. X-CTU can either be downloaded from DIGI s website or installed from an installation CD. The figure below shows how to connect the Z232 to interact with the X-CTU software. ** See the X-CTU User Manual for detailed information on using the utility. Connect cable to J3 of the Z232 with the red stripe towards pin 1. Connect the other end (DB9-Female) to an available COM port on the PC. Figure 4.1 Connecting the Z232 to X-CTU 4-1

Reference source not found.software Default Network Configuration configures the XBee modules to operate in a NonBeaconing system where one device is a Coordinator and the other devices are End Devices. configures the Coordinator to broadcast to all End Devices and the End Devices to transmit to the Coordinator. The X-CTU software can be used to configure a device for Coordinator or End Device. See the XBee/XBee-PRO and the X-CTU user manuals for detailed information.
