4.2 Operation

Galaxy router is an embedded hardware and software platform. Normally, it is working without any manual operation. It provides a reliable and flexible data channel for industrial applications.

Galaxy router should be installed at place with good radio signal receiving. For the cabinet and basement environment, we recommend to extend the antenna.

For outdoor use, lightning should be considered. We propose to install an arrester between antenna and the ANT interface. Contact Hongdian technical support department for details.

4.3 Trouble Shooting
