SNAP Stick USB (SS200-001)
The SNAP Stick USB device is used to enable a PC to communicate with local SNAP
nodes.
This device, based on the ATMEL ATmega128RFA1 hardware, is a USB dongle, about the
size of a thumb drive. It is designed to act as a bridge between Synapse’s management
tool, called Portal, or Synapse’s Internet connection
capability, called SNAP Connect, and your other SNAP
nodes.
Because it is based on the ATmega128RFA1, the SS200
has the same capabilities as the underlying hardware,
relating to sleep options and radio rates as discussed in-depth in the SNAP Reference
Manual.
The USB dongle form factor means that only one UART is available on the SS200. UART1
connects through the USB port. If you change the default UART (NV Parameter 12) to 0,
you will not be able to communicate directly with the device, and will have to either use
Portal to reset the device to Factory Default Parameters (NV Params) or use a different
SNAP Device as a bridge and reset the default UART over the air.
Also because of the form factor, you do not have normal access to the GPIO pins on the
SS200. The device was designed to primarily act as a bridge device. The only feedback
available from the device comes in the form of a tri-color LED, controlled by pins 5 and
6, as shown in the following diagram:
