Appendix B Bi-directional communication

The total station controlled by external computer can sent the
information about angle and distance. The settings of communication
and protocol as follow:
● Baud rate: 2400~115200 available
● Data length: 8
●Stop bits: 0
●Parity bits: none
●protocol:
●Code: STX（02），CR（13），X_ON(17)，X_OFF(19)
The angle ans diatance data are transferred by a form of fixed
length of 7 byte. The unit of angle is " ° ' "
is "mm";
Command frame list("＋" means connection)
1. Check communication
Ask: STX+T+C+CR
Respond: X_ON
2 Set the horizontal angle
Ask: STX+S+A+HHHHHHH+CR
Respond: X_ON
"HHHHHHH" indicates azimuth angle. Example: 120°43'55"
can be explained "1204355"
3. Read angle data
Ask: STX+R+A +CR
Respond: STX+R+A+HHHHHHH+VVVVVVV+CR
"HHHHHHH" is azimuth angle
"VVVVVVV" is vertical angle
4. Read distance and angle data
Ask: STX+R+D +CR
Respond:
STX+R+D+HHHHHHH+VVVVVVV+DDDDDDD+CR
"HHHHHHH" is azimuth angle
"VVVVVVV" is vertical angle
"DDDDDDD" is slop distance
5. Start measuring
Ask: STX+D+S+CR
Respond: X_ON
6. Stop measuring
Ask: STX+D+T+CR
Respond: X_O
