About the Digi Connect Wi-ME Embedded Module C H A P T E R 1 Overview The Digi Connect Wi-ME 9210 b/g is a fully customizable and secure 802.11b/g wireless embedded module that provides integration flexibility in a variety of connection options. Built on the new Digi NS9210 processor in combination with a 802.11bgn Wi-Fi radio, it is pin-compatible with the existing Digi Connect Wi-ME 802.11b module allowing customers to easily migrate to the next-generation version of the product.
Types of Modules There are two types of modules. One module utilizes Digi Plug-and-Play Firmware, while the second is customizable with the option to develop a firmware application in .NET MF or NET+OS. If you are developing your firmware application in NET+OS, you will be using a module with a JTAG interface. Note: JTAG is a commonly used term that is also referred to as IEEE 1149.1, an industry standard test protocol.
Connectors: Power and Device Interface Difference in pin assignments/availability Digi Connect Wi-ME 9210 module uses a 14 pin male connector that fits into the Digi Connect ME family 20 pin foot print. Pins 1 through 6 are not used and have been removed from the Connect Wi-ME module. The pin assignment table shows the appropriate values.

Jumper is in the 1/2 position Hard Reset The embedded modules support a hardware reset on pin 8 of the 14-pin header. Pulling pin 8 low with an open drain driver will force the module into a hard reset state. The module will remain in the reset state as long and pin 8 is held low and will leave this reset state ~250mS after pin 8 goes high. Do not actively drive pin 8 high and do not allow the rise time of the pin 14 to be longer than 100uS.

Module JTAG Interface Connector, P11 The Module’s JTAG Interface Connector is a 14-pin female vertical header that is labeled P11 on the development board. The connector mates with the JTAG connector on the embedded module. The Module’s JTAG Connector pins are tied to the debugger connector (see “JTAG Debugger Connector, P12”). Since the modules' JTAG connectors are mounted on the bottom side of the modules, the pin 1 location is mirrored from that of the Development board's mating JTAG connector (P11).
JTAG Debugger Connector, P12 The JTAG debugger connector is a 20-pin male vertical header that is labeled P12 on the development board. The connector mates with a JTAG debugger plug (for example, a Digi JTAG Link). The connector is used with the development kit only. See the following figure for pin orientation. See the following table for pin assignments. The figure shows the connector using the same orientation as shown in the figure titled "Board Layout and Connector Locations:" on page 14.
Logic Analyzer Header, P3 The Logic Analyzer Header is a 20-pin male vertical header that is labeled P3 on the development board. The header is for connecting a digital signal analyzer (for example, a logic analyzer) to the development board. See the following figure for pin orientation; see the following table for pin assignments. The figure shows the connector using the same orientation as shown in the figure titled "Board Layout and Connector Locations:" on page 14.
Switches and Push Buttons The development board provides the following switches: User PB1 User PB2 GPIO Switch Bank 1, SW3 Reset, SW4 Power On/Off SW5 See the figure titled "Board Layout and Connector Locations:" on page 14 for the location of the switches.

Module Pinout General Information The NS7520/NS9210 processors support 16 General Purpose I/O (GPIO) lines, some of which are reserved for specific functions and some of which can be customized. For Digi Plug and Play Firmware users, see the Digi Connect Family Users Guide for details on what Pin configurations are available to you. Module Pinout The following table provides signal header pinout information for the Digi Connect ME, Digi Connect Wi-ME and Digi Connect ME 9210 modules.

Reset Hard Reset The Wi-ME 9210 module supports a hardware reset via pin 8 of the 14-pin header. The unit is forced into a hard reset when pulling the pin to ground, or less than 0.8v, for one microsecond. When plugged into a development board, this pin is wired to the push button at SW4. As a result, this switch acts as a hard reset button. Reset Characteristics Characteristic 32 Specification Delay 250 milliseconds (typical) Low ActiveThreshold 0.8 V High Inactive Threshold 2.
Memory Flash Depending on the variant, the Digi Connect Wi-ME 9210 has 8 or 16MB of flash memory. The Digi Connect Wi-ME 9210/ARM9 family, the flash memory is controlled by chip select 2 (default=st_cs1) and is located at 0x50000000. SDRAM The Digi Connect Wi-ME 9210’s SDRAM is controlled by chip select 1. Depending on the variant, the module will have either 8 or 16MB of SDRAM memory. The following table illustrates typical power consumptions using these power management mechanisms.

Power Management (Digi Connect ME 9210 only) Using the Digi NET+OS development environment, applications on the Digi Connect WiME 9210 are capable of operating the module in several reduced power consumption modes. These reduced power operating modes utilize the power management mechanisms for the NS9210 processor for CPU clock scaling and sleep.
Thermal Specifications The table below shows the standard operating temperature ranges for the entire Digi Connect ME family of embedded modules.. Standard Operating Temperature Ranges Product Operating Temperature Range Digi Connect Wi-ME 9210 -40C to 64C no external thermal pad -40C to 85C external thermal pad The lower standard operating temperature ranges are specified without restrictions, except condensation must not occur.
Additional Design Recommendations The following list provides additional design guidance with respect to thermal management in applications with operating temperatures at the high end or beyond the specified standard ambient temperature range. Providing air movement will improve heat dissipation. The host PCB plays a large part in dissipating the heat generated by the module.
Bar Code The 50m PN is code 3 of 9 (39) and the MAC is code 128. All scanners are set up so if they read code 3 of 9 they will automatically read 128. The reason for the two different code types is to maximize the size of the bars within a given space to improved readability.
