    Synapse’s Portal software Other Important Documentation The E10 is typically running Synapse’s SNAP Connect software internally. Be aware that SNAP Connect has its own dedicated user manual. You will likely need to refer to that manual to develop your own applications using the SNAP Connect Python library, as much of the fundamental information on SNAP Connect is not repeated here.

    Or, it could be that environmental factors prevent a good radio signal from reaching other parts of the network. In either case, an E10 as part of each subnet, linked by the wired TCP/IP network, allows all the subnets to work together as one large network. SNAP Connect E10 Users Guide – 600034-01B...

    SNAP Lighting From Anywhere In The World When combined with Synapse’s SNAP Cloud product, E10s support tunneling through firewalls to allow full connectivity to wireless sensor networks from any web browser. If your E10 is part of a SNAP Lighting kit, there will be a Kit-ID and password on the bottom sticker of the E10.

  • Page 16: Snap Connect E10 Overview

    The E10 is a SNAP Node with Serial, Ethernet and USB Interfaces To act as a SNAP Node, the E10 runs Synapse’s SNAP Connect software. This gives the E10 the ability to perform mesh routing over the Internet, letting SNAP Nodes in one networked location access a SNAP network in another location.

    SynapseMain.py shuts itself down. Furthermore, it is not possible for Synapse to specify a definitive delay period before you should start holding the button because the time it takes to boot your E10 will depend on factors such as your network configuration (Ethernet or Wi-Fi, plus your network speed and the speed at which your NTP server responds).

    The E10 comes with driver modules installed for several popular Wi-Fi chipsets. While the drivers for these chipsets have been installed, there are no guarantees that all devices that use these chipsets will work. Synapse has tried to include support for a wide variety of common devices, but we cannot possibly test every USB Wi-Fi adapter on the market to ensure that drivers behave as expected.

  • Page 27: Setting Up Your Wi-Fi Connection

    If you wish to define a static IP address instead of having the E10 acquire one dynamically, instead uncomment the iface wlan0 inet static line, and the address, netmask, and gateway lines, filling in the appropriate information. SNAP Connect E10 Users Guide – 600034-01B...
