I. Introduction
• Everything you need for full
NAFEM protocol compliance
• Translates and organizes your
legacy equipment's data into the
NAFEM Data Protocol framework
• Supports all of the MIBs defined
by the NAFEM Data Protocol
Group
• Built-In Web Server
• Optional Modem for installations
without a network infrastructure
• Connect up to 253 equipment with
one MicroGate™
• Firmware Upgradeable in the field
as protocol standards change
E-Control Systems MicroGate™ is one of the most cost-effective and versatile gateways
for adding the NAFEM (North America Association of Food Equipment Manufactures)
Data Protocol and Ethernet connectivity into any equipment. Whether you're an
equipment manufacturer, systems integrator, or IT manager, the cost, functionality, and
flexibility of the MicroGate™ makes it the ideal product for any Online Kitchen™
application.
The MicroGate™ incorporates all essential networking functions including a full-featured
TCP/IP stack, 10Base-T Ethernet connection, real-time operating system, embedded Web
Server, optional modem, and battery-backed memory.
Feature-Rich Cost-Effective Solution
The MicroGate™ incorporates the latest in Flash and SDRAM technology to give the
best feature/price/performance ratio on the market. Using the latest in memory
technologies allows up to 253 pieces of equipment to be connected to one MicroGate,
further reducing the cost of the overall system. Complex menu recipe changes, firmware
updates, or set point changes can be done without disrupting any of the other services
running on the MicroGate™.
Flexibility
As the demand for updates and new features arise, the MicroGate™ can be updated from
any location on the Ethernet network. This eliminates the need to call for service or
replace the hardware itself. All updates and features are added using a standard Web
Browser, like Microsoft® Internet Explorer, or through bulk transfer facilities specified
in the NAFEM data protocol.

IV. Installation and Configuration
System Requirements
You must meet the following requirements to install and configure the MicroGate™:
• Static IP address, Subnet Mask, and Gateway Address to assign the
MicroGate™
• A computer equipped with a 10 Mbps, 100 Mbps, or 10/100 Mbps Fast
Ethernet Card, or USB-to-Ethernet converter. Computer must have TCP/IP
protocols installed and have a fixed (static) or dynamic IP Address assigned to
it.
• MicroGate Discovery Utility CD (might be bundled with Raptor Web
Software™ CD)
• Network Cable connecting MicroGate™ directly to the computer (use a
hub/switch that the computer is connected to (use Straight-Through type
• +5VDC Power Supply with mating connector
Connect the System
The MicroGate™ can be placed at any convenient location in the kitchen or office.
No special cooling requirements are needed, but you should keep the MicroGate™
away from any heating device, dusty or wet environments. If the MicroGate™ needs
to operate in a dusty or wet environment, it should be placed in a NEMA box. Make
sure to disconnect the power, remove the power cord from the outlet, and keep your
hands dry when handling the MicroGate™.
Basic Installation Procedure
1. Connect an Ethernet Cable from the MicroGate™ to one of the following:
b. Ethernet Port on hub, switch, or router using a Straight-Through type
2. Connect a serial cable from your device(s) to one of the serial ports on the
4. Plug the other side of the power cable to a +5VDC source, or to a wall outlet
if you are using a cable with power supply
6. After approximately 30 seconds, verify that DS3 (Heartbeat) LED is flashing

Basic Network Configuration Procedure
1. Start the Discovery Utility by selecting Start > Programs > Raptor Web
Software > ECSDiscovery – This utility might reside in a different location
depending on how it was installed.

3. A list of all of the ECS units on the network is listed sorted by their MAC
that you want to configure (the MAC address is shown on a white label on the
underside of the MicroGate™). Highlight the row in the table that corresponds
to the correct MAC Address/Unit you want to re-configure.

5. Change the IP Address, Subnet Mask, and Gateway Address as needed and
6. Writing the configuration and restarting the unit can take as long as 2 minutes.
In that time you will see DS3 stop flashing. When it starts flashing again you
are done configuring the MicroGate™. Note: You can also verify that the
MicroGate’s configuration changed by clicking on Start Discovery (see
address column of the MicroGate that was configured changed to the new
value.
Congratulations! You have successfully configured the MicroGate™. For advanced
configuration information, please see the Raptor Web Software™ Users Manual.
