Networking Guide
Initial Setup
1. Make sure that Phidget21 is installed on your computer.
2. Install Bonjour (recommended)
3. Plug the PhidgetSBC into your network and power it up.
The PhidgetSBC will try to get an IP address from DHCP, which should work on most networks. If there isn’t a DHCP
server running, then it will fall back on Link Local addressing. In order to find the PhidgetSBC on your network, you
either need to look at the DHCP server log, or use Bonjour. DHCP servers are provided by most home routers, and
by your ISP.
It is typical for the PhidgetSBC to take as long as a minute to appear in the Phidget Control Panel when connected,
and longer to be removed from the list after being disconnected.
Zero Configuration Networking
We recommend that you install the Bonjour utility for simpler networking with the PhidgetSBC through Zeroconfig.
For Macs, Bonjour is already installed.
•
Windows users can get it from: http://www.apple.com/support/downloads/bonjourforwindows.html. After
•
installing, a reboot may be required for the Phidget Control Panel to function.
Linux users should use Avahi, which if not installed will be available as a package.
•
Bonjour lets you access your PhidgetSBC without knowing its IP address. Multicast DNS (part of Bonjour) will expose
each of your PhidgetSBCs using a .local hostname, which you can use anywhere an IP address would be used. The
default name for the PhidgetSBC is ‘phidgetsbc’ - so ‘phidgetsbc.local’ would be its mDNS hostname.
If you have more than one PhidgetSBC on the network, their host name will appear like phidgetsbc.local.,
phidgetsbc-1.local., phidgetsbc-2.local., etc. They will also be given the server ID usually similar to the host name as
phidgetsbc, phidgetsbc (1), phidgetsbc (2)... etc.
If you use Bonjour, any PhidgetSBCs on the network will show up in the Phidget control panel (windows) or Phidget
preference pane (Mac). For Linux users, there is a tool in the examples folder of the library download, which will list
PhidgetSBCs. The PhidgetSBC will also show up in the Bonjour tab in the Safari web browser.
You can identify a specific PhidgetSBC by matching the MAC address reported in the Phidget control panel with that
printed on the label on the underside of your PhidgetSBC.
Setting up an Ethernet Connection
Simply plug an Ethernet cable from your network into the Ethernet port of the PhidgetSBC. By default, the
PhidgetSBC will set the system IP address, subnet mask, and gateway automatically. If Bonjour or Avahi is installed,
then the PhidgetSBC will automatically register itself with mDNS when connected.
Setting up a Wireless connection
The PhidgetSBC supports wireless networking via the available USB Wireless adapter. The Wireless antenna should
be kept in clear space as performance can be dramatically reduced if it is handled, or if it comes into contact with
objects. To initially configure the wireless, you must first connect to the PhidgetSBC configuration interface through
Ethernet.
