Page 5: Installation
GI4200 High-precision fiber optic integrated navigation system Installation The GPS antenna we routinely select is a zero-phase measurement one, and general navigation antennas cannot be used in this product. Although some navigation antennas can also be directional, the accuracy will be greatly reduced and errors may also result. If the user replaces an antenna that is not configured or designated by the company, the system will not work properly or other consequences will occur, and the company is not responsible for this. - Page 6 GI4200 High-precision fiber optic integrated navigation system Electirc connection Data cable RS422 interface definition, DB9 female: DB9 Connector pin Interface Definition Remark Receiving positive Receiving negative Receiving positive Receiving negative Debugging software ①Ensure that the inertial navigation is absolutely stationary, correctly connect the serial port Steps for usage：...
