Types Of Modules - Digi Connect ME Hardware Reference Manual

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.

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 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:
The following figures show the two types of modules.

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.

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.
