NOTES:
1. Shielded twisted pair cable should be used for connection.
2. The maximum distance of the whole interconnection is 50m, i.e. the connection distance count from the first
antenna to the last antenna should be less than 50m.
3. Each set of antennae can have only one Master and the other Slaves. One Master antenna can link with a
maximum of 30 Slave antennae.
4. Distance of each synchronization cable should not be more than 30cm from main cable.
