4.2.5.7 Slave Cable Connection
When two RU or more enclosures are installed for supporting multi-band. One is designated the Master
Remote Unit and each additional RU, up to two Units, are designated as slave Remote Units. The Master
and slave Unit(s) is specified by the frequency band. The Master Unit will separate the bi-directional signal
related to the frequency and provide the RF input signal to each slave Remote Unit. The connection
between Master and Slave is interfaced with the RF cable provided with the Remote Units.
Use the following procedure to install the antenna cable:
 All designated slave RUs arrive with two RF cables.
 Connect one RF cable to the port labeled “TX_OUT” on the MASTER Remote Unit User Interface.
