QUOTE(tcplomp @ Apr 10 2007, 10:11 PM) I did try other commands...i changed the port number ( and made sure I connected the servo to the chosen port), the position and speed, but i still get the same response...one blink of the LED.

I did follow what the example said...i didn't get any response from my servo. I thought maybe writing it in a different format might help. I was also wondering...the example is for PBasic...not LabVIEW. Could that be a reason why....when i send '7811 0206 7200'....the LED blinks once? i.e. the message format is going through using LabVIEW.

I have attached the block diagram of the labview program i am using to send signals to the servo board. I tried to do what was mentioned, but the servos still dont respond. Is there a way of converting the Hex command into binary and then passing it through the VISA block? And sorry about the bold text, i didnt realise it could be taken as shouting. I do apologise. First time using a forum...so am learning. Many thanks. here is the diagram again

Hello, I am trying to send the following command packet: $78 $11 $02 $06 $72 $00 to a picoboard which will control four servos. The command packet will be sent through a RS 232 serial port. The values in the command packet are in hex? The first number is the Servio's (board) default address. the second number is the port number. the third is the servo function command. the fourth and fifth are the positioning of the servo in 16 bit hex format with the most significant bit first. the sixth is the speed with which the servo should move. An example of using the above packet is provided in the user manual (pages 12-14). the manual is available from http://www.picobotics.com/ServioManual.html. I have tried sending the packet as it is...but my servo does not respond. Am i missing something? Do i have to use some converter in LabVIEW to send the packet? I would be grateful for any input. Thanks.
