    Elevator connector Installing into the Tower System: In additional to functioning standalone, the TWR-RF-SNAP is designed to be used in the Freescale Tower System. When inserted into the Tower System a Tower MCU module can utilize the TWR-RF- SNAP to relay information to additional SNAP nodes, including the provided SN132 USB Dongle. The TWR-RF-SNAP can also access compatible peripheral modules directly using I2C and SPI.

    Software Features This section provides more details about the software features and functionality of the TWR-RF-SNAP including the Synapse Wireless Portal IDE and python based SNAPpy scripts. 3.6 SNAP / SNAPpy Synapse's technology is an Internet-enabled, auto-forming, multi-hop, mesh network Operating SNAP®...
  • Page 14: Synapse Portal Ide

    The MAC address is printed on the label of each SNAP device. For a quick overview of installing the Synapse Portal IDE and the necessary USB drivers refer to the TWR-RF-SNAP Lab Guide. The Default View of Portal IDE consists of the following key panels and tool bars: Main Toolbar, Node View Panel, Node Info Panel, Node Info Toolbar, and Event Log Panel.
  • Page 15 Event Log Figure 5 - Portal IDE Application With the SN132 USB Dongle connected to the PC running the Portal IDE and the TWR-RF-SNAP powered externally and within range of the SN132, the application will identify the USB Dongle as an available SNAP Bridge Device on Port USB0.
  • Page 16 Figure 6 - SNAP Bridge Device Connect The application will then attempt to identify all available Nodes available in the network as seen in the figure below. The TWR-RF-SNAP will be identified as a SNAPTower Node (Device Type: TWR_SNAP). Figure 7 - SNAPTower in Portal TWR-RF-SNAP User’s Manual...
  • Page 17 SNAP Node is first selected in the Node View panel. For example, to upload a new script to the TWR-RF-SNAP Tower Module, you must first ensure that the SNAPTower Node is selected in the Node Info panel as shown in the image below.
