4Chapter 2. Installation 2.1 Step by Step Installation 2.1.1 Mounting Bracket Assembly Suite The following hardwares are suggested for mounting the Transceiver to the pole. A set of mounting bracket, one L type screw. Please contact TSI sales department for this accessory.
52.1.2 Step by Step Installation Step 1 – Attach sequence Left to right: Bracket , Mounting screw. Step 2 – How to Attach The concave of Bracket 2 is for holding onto the pole. Step 3 – Tighten the bracket
6 2.2 Connection to the Power Inserter and Cable Modem Connections to the Tranceiver are shown in diagram 2.2. Please note: ① The power inserter normally has 3 ports: DC Connect to wall adapter with RG-59 cable ANT Connect to the Transeiver TV Connect to Cable modem VERY IMPORTANT NOTICE! a. The power inserter should be correctly connected, or the Transeiver will not operate. b. Ensure that all wires and cables are hooked up before plugging into the AC adapter/power supply (i.e. you must hook up the power supply last). ② After connection, the F connector of Transceiver must be sealed with an asphalt sealing tape. (For details, please refer to Section 2.3 Waterproofing Connections) Diagram 2.2: Connection to Cable modem & Power Inserter
72.3 Waterproofing Connections Water-proofing is very important during installation of Transceiver. Please use the included water-proof asphalt tape to seal off the F-connector as shown below: ① After you plug in the coaxial cable into the F-connector, use the included water-proofing asphalt tape to seal off the F-connector from the bottom (i.e. the part close to Transceiver). Note that the tape must wrap up all the thread of the F-connector. ② The wrap up of the tape must be tight and sturdy. Each wrap-around must cover at least 50% width of the previous wrap-around.
8③ The total width of the wrap-around is about 6cm, which corresponds to 7 to 8 rounds of tapes. * Warning: If you do not follow the above procedure, the Transceiver could become malfunctioning due to water leakage.`
