Communicating with rcm3100 through serial port component in vb.net

Hi Stefan,
You need to write some code to send and receive serial data to the Rabbit.
You then need to receive this on the Rabbit, decode the message and then
switch the Port as required. Is quite trivial to do if you know how to send
and receive serial data on the Rabbit and in VB.
For VB, simply drop a serial port component on the form, set the properties
to match the speed of the Rabbit serial port and then add a call to send
data on the serial port. Remember to open it first.
For example, to switch the port ON send something like this.
Dim Telegram As String
Telegram = "$1#"
SerialPort1.Write(Telegram)
The $ is the header (always useful to locating the start of a message), the
1 is the state of the Port Pin and # is the end of telegram.
To switch the port off, use this.
Dim Telegram As String
Telegram = "$0#"
SerialPort1.Write(Telegram)
This time, the 0 says to switch it off.
This is just a little insight into the way to do this as there is many more.
In most cases I also add a CRC/checksum to the message to act as a check
that the data was good.
You'll need code on the Rabbit to receive this and decode it.
If you can get this all working on your own, then you will have a great
understanding of how serial comms works and how to programme it for the
Rabbit. There is a quite a few samples supplied with the Rabbit so I am sure
you will figure it all out! Good luck.
Hope this helps
Regards
Dave...

Hi!
I would like to know how to use serial port component in vb.net to
communicate with port pins on the rabbit rcm3100? For example, say I am
using port A and I would like pin PA5 to go low or high, how do I accomplish
this with vb.net serial port? I went over to "help with vb groups" but I got
no response.
