Can I choose the baud rate and the data output rate? Where I can found the command protocol datasheet** A: Hi When connect the power,the device will be work.and it can not be reprogramable.and you can choose baudrate ,the default is 9600,I give the link for the document and the PC software,you can download it.thanksJY901 User manual: https://drive.google.com/file/d/0B8PmY6nhQadKQm1YNS1jZml4OVE/view?usp=sharingQuick start:https://drive.google.com/file/d/0B8PmY6nhQadKeEdBOV90WmhNRU0/view?usp=sharingJY-901 material:https://drive.google.com/file/d/0B8PmY6nhQadKLWdxN2VNY1E1OWc/view?usp=sharing **Q: Is it possible to record the data graph for playback later as a moving graph?** A: Yes it is possible. Data can be recorded and played back in our software. **Q: On the magnetic channel is there a way to change it to display from 0 to 359 degrees instead of + or- degrees? (it's for a radio telescope azimuth).** A: Dear sir or madam, Thanks for reaching out and let me know your concern. Sorry for the delayed response. Our company is on Chinese New Year Vacation from 1st Feb. to 1st March. 2020. Even on vacation, the email will be replied to within 2 working days. Your understanding and patience would be hugely appreciated. 1. The degrees can only be +- format. It is a fixed design **Q: where can I find the app for mobile phone where I can have my data recorded** A: Hello Kunde, Thank you for reaching out and letting me know this situation.
