Re: [Paparazzi-devel] RS232 Control Lines

[address@hidden]

Standard usb will go 5 meters and you can daisy-chain several 5m repeater 
cables to go really far.  This will give you all your flow control and power in 
a trivially easy package.

But to answer your question, flow control is most interesting on the airbone 
side so that packets can be sent more efficiently.  The ground modem is not 
sending much so it's not much concern there.

Group,


  There was some discussion about swapping UARTs on the Tiny to allow
hardware flow control to be implemented on the XBee modems.  Is this the
direction the ground modem datalink will be going as well?  Should we
plan to implement hardware control lines on the ground modem?

  I am designing a datalink modem enclosure with a watertight enclosure,
environmental connectors, integrated ISR for 5-18V, and ~ 30 feet of
multiple conductor cable to allow me to place it up a pole, etc. I would
like to know if I can use 4 conductor cable or should plan for an extra
2 conductors.  Thanks.


Cheers,
Matthew
