 8About the Digi Connect ME Family of Embedded ModulesCHAPTER 1OverviewThe embedded modules provide fully transparent device connectivity over industry-standard Ethernet connections and allows both equipment manufacturers and systems integrators to network-enable products at a fraction of the time and cost required to develop a custom solution. It is a highly flexible and compact single component solution with a serial port, GPIO, and a robust on-board TCP/IP stack and 10/100 BASE-T Ethernet support or wireless interface.Built on Digi's leading 32-bit NET+ARM processor technology, the Digi Connect ME family of embedded modules offer serial-to-Ethernet functionality through Digi’s Plug-and-Play Firmware firmware, or the freedom and flexibility of professional embedded software development provided by the easy-to-use, cost-effective and complete Digi JumpStart Kits™ for NET+OS and Microsoft .NET Micro Framework.The Digi Connect ME and Digi Connect Wi-ME modules are utilizing the powerful Digi NS7520 processor with an ARM7TDMI core running at 55 MHz. They provide integrated wired or wireless networking and serial device connectivity in a compact connector-style form factor. The Digi Connect ME 9210 module is the latest, fully form factor and pin compatible, member of the Digi Connect ME family providing 75 MHz ARM9 core performance based on the Digi NS9210 processor. In addition to higher performance with integrated Ethernet connectivity, the Digi Connect ME 9210 offers higher serial data rates,
9 SPI functionality, as well as the unique option of application specific interfaces using the programmable FIMs on the NS9210. From medical systems to building control and industrial automation, in virtually any application where embedded device connectivity over Ethernet or wireless connectivity is needed, embedded modules are the ideal choice, delivering high-performance functionality.Note:Unless mentioned specifically by name, the products will be referred to as the embedded modules or modules. Individual naming is used to differentiate product specific features. Similarily, information about the Connect ME applies to the Connect ME 9210 as well unless stated otherwise.This chapter provides information about the modules hardware and contains the following topics:"Types of Modules" on page 9"Connectors: Antenna" on page 15"Connectors: Ethernet Interface" on page 14"Module LEDs" on page 16Types of ModulesThere 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 applicaton 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. JTAG is an abbreviation for the European Joint Test Action Group, which invented the first versions of the IEEE 1149.1 interface. The JTAG interface, along with the other development tools, enables you to download, run and debug programs on the module.The following figures show the two types of modules.

15 Hard ResetThe embedded modules support a hardware reset on pin 14 of the 20-pin header. Pulling pin 14 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 14 is held low and will leave this reset state ~250mS after pin 14 goes high. Do not actively drive pin 14 high and do not allow therise time of the pin 14 to be longer than 100uS. When used with the development board, this pin is wired to reset button SW4, which means it acts as a hard reset button.Connectors: AntennaThe Digi Connect Wi-ME is available with 1 RP-SMA connector. The antenna is connected to the module with a reverse polarity SMA connector (sub-miniature size A). The antenna only fits on the module one way to ensure a proper connection. Another option for both signal reception and design flexibility is to use an antenna extension cord to separate the antenna from the module. This allows the module to fit inside your product but the antenna to be placed outside the device.

LEDs41Digi Connect ME, Digi Connect Wi-ME & Digi Connect 9210 Hardware ReferenceLEDsGeneral InformationThe embedded modules have two types of LEDs: An LED connected directly to GPIO pins on the processor and controlled directly in softwareAn LED connected to other hardware components (normally the Ethernet hardware) and not directly programmable by the operating systemThe development kit, by default, correctly configures the GPIO connected to the LED as an output and then uses this LED to represent Ethernet activity. Reset Hard ResetThe embedded module supports a hardware reset via pin 14 of the 20-pin header. The unit is forced into a hard reset when pulling the pin to ground, or less than 2.88v, for one microsecond. When plugged into a development board, this pin is wired to the push button at SW3. As a result, this switch acts as a hard reset button.LED DescriptionYellow This is wired directly to Ethernet hardware and provides an indication of link.GreenThis software-programmable LED is wired to processor GPIO register bit C6/GPIO[14] and is wired to be lit when low. The default behavior is to blink on Ethernet activity.Reset CharacteristicsCharacteristic SpecificationDelay 250 milliseconds (typical)Threshold 2.88 V

 50Power Management (Connect ME-9210 only)Using the Digi NET+OS development environment, applications on the Digi Connect ME 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 Digi NS9210 processor for CPU clock scaling and sleep.In the Clock Scaling mode, the system itself continues to execute instructions, but at a different clock rate, which can be changed on-the-fly, using Digi’s patented circuitry inside the NS9210 processor. The clock speed is changed programmatically to lower or raise the system clock speed, thus reducing or increasing the module’s power footprint, respectively.Additionally, a Sleep mode is available in which the system stops executing instructions. Based on the application needs, wake-up triggers can be set up programmatically to activate the processor back to wherever it left off. In this mode, a drastic power reduction is realized by reducing the power consumption of the Digi NS9210 processor and the on-module PHY.For sample power consumption figures for normal (typical) and power management related operation of the Digi Connect ME 9210, see below:3.3VDC @ 346 mA typical (1.14W)UART and Ethernet activatedLow Speed Idle Mode (approximate)3.3VDC @ 186 mA (613 mW)/16 clock scaling, Ethernet activatedSleep Mode (approximate)3.3VDC @ 34 mA (113 mW)Wake-up on EIRQ, Ethernet PHY off

 52Additional Design RecommendationsThe 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. A large copper plane located under the Digi Connect ME 9210 and soldered to the module’s mounting tabs will improve the heat dissipation capabilities of the PCB.If the design allows, added buried PCB planes will also improve heat dissipation. The copper planes create a larger surface to spread the heat into the surrounding environment.Adding a thermal pad or thermal compound, such as Sil-Pad®, Gap Pad® or Gap Filler products made by the Bergquest Company (www.bergquistcompany.com), between the host PCB and the underside of the module will significantly increase the thermal transfer between the module’s enclosure and the host PCB. Limit the fill area to the folded metal portion of the module’s underside.Measure Temperature HereMeasure Temperature Here
