1 Introduction to EM2COMIF
The Intel Enpirion dongle (EM2CONIF) is to support interaction between the Internal Enpirion Digital
Power Configurator and supported Digital Modules. The dongle interfaces between a USB port on a
host computer to an Intel Enpirion Digital Power Module mounted on a printed circuit board. The
dongle communicates from the host computer to a standard 10-pin header connected to the Digital
module. You can use the dongle to iteratively read-back or download configuration data to a module
during prototyping or debug though the GUI.
1.1 Supported Devices and Host Systems
You can use the EM2COMIF with supported Intel® ENPIRION Digital Power Modules and
host systems using Intel® ENPIRION Digital Power Configurator

2 Specifications for EM2COMIF
The EM2COMIF dongle has a universal USB connector that plugs into the PC USB port,
and a female connector that plugs into a male header on the device board. This
section shows the hardware components, their dimensions, and lists the pins,
operating conditions and power requirements.

2.2 Cable-to-Board Connection
The EM2COMIF has a 10-pin female connector, which plugs into a 10-pin male header on the device
board. The male header consists of two rows of five pins, which are connected to the programming
or configuration pins of the device. The PIN 1 side of the header is indicated through a color s stripe
on the ribbon cable.
A 10-pin surface mount header can be used for the download cable. However, Intel® recommends
using a through-hole connector in the event of the repeated insertions and removals.

The EM2CONIF is powered through the USB 5V supply. The SCL, SDA & SALERT pins are pulled up
internally to a 3.3V supply via 4.7kΩ resistors. A pull-down resistor of 4.7kΩ is connected internally
between the POK and ground. A pull-down resistor of 4.7kΩ is also connected internally between the
Control pin and ground.
For PMBus communications only three pins are required to be connected, SCL, SDA and a ground pin.
3 Using the EM2COMIF
To start using the EM2COMIF, you must install the Intel Enpirion Digital Power Configurator on your
system.
To program or configure a module device, connect the host system to the device board using the
EM2COMIF and the GUI should then connect automatically. Please refer to the INTEL Enpirion Digital
Power Configurator for further information.
For PMBus communications only three pins are required to be connected, SCL, SDA and a ground pin.
