Hi all , i am trying to send serial data from the housebot to a serial interface , i am able to see the data coming from my device into house bot but i am not able to send a control string back to my device. I want to send the string S_GR,1,100,100 this controls a group id and sets a relay 1 to 100 %.

I have set up and interface and set the write data to the above but it does not seem to be sending the data out.

Regards Newbee :roll:

1)Created serial interface definition ?

2) Added commands to serial interface definition ?

3) Created Serial device with property(ies) ?

4) Mapped property values for serial device property(ies) to commands in serial definition or set up for substitution strings ?

Can you give me the exact setup in HouseBot for the serial Command that you are trying to send? Is it Hex or ASCII? Are you using a command terminator?

S_GR,1,100,100

after this string i need a carriage return and possibly a line feed I am using ascii as the device i talk to needs asci. i have tried CR and LF but its sends the data as CR LF . When i view a CR from hyper terminal it comes up lower case c over lower case R

thanks

If your command is setup as an ASCII command, you can't really send the CR LF by typing them in the command and they won't be sent automatically without you telling it to.

The easist thing to do is to use the command terminator for this. Its job is to append the hex terminator specified to each command that is sent. So if your equipment requires that all commands end with CR LF, just enter 0D0A as the command terminator.

Another alternative is to convert the ASCII characters in your command to hex and then use 0D0A as part of the command string.

Checkout the online help for the Generic Serial Hardware Interface. It will give more specifics.
