Note:
It is recommended to use shielded twisted pair wire.
Multi-Sync connection
To use two or more Base Stations with Remote Antennas and Repeaters together in one antenna coverage,
Multi-Sync connection, which is described hereafter, should be made for the best communication performance.
A Base Station must be set as a ‘primary on’ (master) and all others as ‘primary off’ (slave) in the ‘Multi-BS’
menu. In this setting, the Remote Antennas and Repeaters are automatically set to the master or slave.
Put wires into the 4-wire& Multi-Sync connector (#4) on the rear panel of the Base Station, by the following pin
connections. Plug the enclosed 10-pin spring clamp connector into the 4-wire& Multi-Sync connector as shown
below Figures. Put wires as following wiring diagram into 10-pin spring clamp connector. To plug a cable wire
into the 10-pin spring clamp connector, push and hold an orange colored wire-release latch on the top of the
connector, then put a cable wire into its relevant pin and release a wire-release latch.
Note
: Coaxial cable to be used for the Multi-Sync connections and it must not exceed a length of 6 feet (2 meter).
