Specifications

Parameter power specifies a transmit power level from 0-17, with 0 being the lowest power setting and
17 being the highest power setting.
This function does not return a value.
ucastSerial(destAddr) – Setup outbound TRANSPARENT MODE
SNAP TRANSPARENT MODE is covered in section 5.
When you want the outbound data to be sent to a specific node, use this function.
Parameter destAddr specifies the Network Address of some other node to give the received serial
characters to.
If you want the received serial characters to go to more than one node, you should use function
mcastSerial() instead.
This function does not return a value.
uniConnect(dest, src) – Make a one-way switchboard connection
The SNAPpy switchboard is covered in section 5.
This function establishes a one-way connection between two points. See included script
switchboard.py for the possible values of parameters src and dest.

See also function crossConnect() if you need a bi-directional hookup. As an alternative, two
uniConnect() calls can be equal to one crossConnect() call. For example:
uniConnect(UART0, UART1)
uniConnect(UART1, UART0)
has the same effect as:
crossConnect(UART0, UART1)
NOTE – A source can only be connected to a single destination. Multiple sources can feed into a
single destination.
This function does not return a value.

Most platforms have two UARTs available, so with most SNAP Engines UART0 will connect to the USB port on a
SN163 board and UART1 will connect to the RS-232 port on any appropriate Synapse demonstration board. However the
RF300 SNAP Engine has only one UART – UART0 – and it comes out where UART1 normally comes out (to the RS-232
port, via GPIO pins 7 through 10). If you are working with RF300 SNAP Engines, be sure to adjust your code to reference
UART0 rather than UART1 for your RS-232 serial connections.
