Page 6: About This Guide
About this guide Scope of the reference manual The purpose of this document is to enable developers to integrate the Digi Connect EM or Digi Connect Wi-EM modules into other devices. Graphics illustrate the placement and dimensions of components for both the modules and the development board. Information for both the Digi Connect EM and the Digi Connect Wi-EM are identical unless called out specifically in the manual. -
Page 7: About The Development Kit
Both kits deliver the integrated building blocks to quickly and cost effectively create your own custom firmware for a Digi Connect EM or Digi Connect Wi-EM based high- performance networking solution that fits the specific requirements of your application. -
Page 8: About The Embedded Module
Input voltage for the module is 3.3 VDC. Types of modules The following describes the three types of Digi Connect EM and three types of Digi Connect Wi-EM modules: Choosing a module for your product Although any of the embedded modules can be designed into your product, a JTAG header would typically be used only for debugging during the development process. - Page 9 The Digi Connect Wi-EM module part number DC-WEM-02T-C or DC-WEM-02T-S is appropriate when its integrated LEDs are accessible and visible to the end-users of your product. The Digi Connect Wi-EM module part number DC-WEM-02T-JT or DC-WEM-02T-NC is the right choice when you want more control over LED locations or when you will provide custom connectors or indicators.

Page 10: Digi Connect Wi-Em Antenna
The Digi Connect Wi-EM is available with dual-diversity antenna connectors. The right antenna (P2) is always used for transmit and receive. The left antenna is receive only. The antenna will choose the best signal (pin vs. socket). The Digi Connect Wi-EM always has two antenna connectors but using the second antenna is optional. -
Page 11: Connectors: Power And Serial Interface
Connectors: power and serial interface This single 12-pin, serial interface port (labeled P4 for Digi Connect EM and P5 for Digi Connect Wi-EM) supports 2 TTL serial interfaces, data rates up to 230 Kbps and full-modem control (on port 1). See the figure for help locating pins and the table for pin assignments. -

Page 13: Reset Switch
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 (Digi part number DC-ANT-E- 24DP) 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. -
