1 Introduction
The eTactica Gateway (EG) is a part of the eTactica line of products, including the
eTactica Power Meter (EM) and the eTactica Power Bar (EB).
The EG collects and analyses your energy data, measured by the EM and the EB. The EG
reads live data from connected devices via its device bus, using Modbus/RTU protocol on
RS485 network (default settings: 19200, 8, E, 1). This allows multiple eTactica devices to
be connected, as well as other 3rd party measurement devices that support
Modbus/RTU.
The EG is a 32-bit Linux platform with Ethernet and Wi-Fi connectivity and acts as a
secure gateway between the electrical panel and the Internet. Measurement data is
securely pushed through any Internet gateway to the your chosen datastore, where the
data is securely accessible from any Internet browser. No need to open ports, just plug
and play. Easy. Secure.
The EG-200 uses an external power supply 9-24VDC, minimum 13W to power itself
and connected devices.

Network Requirements
The Gateway has some network requirements for proper operation. We recommend
that you talk to your IT department before installation, so they can have their part ready.
The exact requirements will vary depending on which software service you wish to send
data to. Some of the common providers are covered in the appendix and some general
guidelines are
DNS access
We expect to have DNS access available. How you configure your network and the EG's
network interfaces (Wi-Fi and LAN) is up to you, but we expect DNS access to be
available.
