Chapter 2 Installation This chapter explains how to mount and install a TR2526+ Broadband Wireless Transceiver. Before performing any of the procedures in this chapter, read all of the installation instructions to ensure that you understand all of the tool requirements and safety guidelines. 2.1 Unpacking the Unit Carefully remove the equipment from its packing material and set it on a solid surface, such as a table or desk.
Mounting the TR2526+ 2.2 Mounting the TR2526+ The TR2526+ was designed for mounting to a pole with a diameter of 1.0" to 1.75". Please ensure that the pole used is attached securely to the building or other mounting location. Mounting the Unit 1) Measure the required length of ground wire (not supplied) and crimp on a ring terminal (not supplied) to one end of the ground wire.
Mounting the Antenna Top View of TR2526+ Mounted on Pole Figure 2-3: Securing the TR2526+ to the pole 5) Place an #8 lock washer onto the #8-32 screw, followed by the ground wire / ring terminal from step 1, followed by a second #8 lock washer and thread this assembly into the ground attachment point provided and tighten. #8-32 Screw #8 Lock Washer Preassembled ring terminal / ground wire Ground attachment location Figure 2-4: Ground wire assembly and connection 2.
Connecting the Antenna Table 2.2 Antenna List Transceiver Power Antenna Type Watts dBm 0.200 23 Flat planar array 0.200 23 0.200 23 Antenna Gain EIRP Watts dBm 16 7.9 39 Dipole/parabolic reflector 21 25.1 44 Dipole /parabolic reflector 24 50.1 47 2.4 Connecting the Antenna Connect the TR2526+ to the antenna via the N-connector. After connection, the N connector must be waterproofed with the supplied rubber sealing tape. See “2.6 Water Proofing Connections” on page 8 for details.
Connecting the IF Cable 2.5 Connecting the IF Cable Connect one end of an RG-59 or RG-6 cable to the TR2526+ F-connector. After connection, the F connector must be waterproofed with the supplied rubber sealing tape. See “2.6 Water Proofing Connections” on page 8 for details. Vecima recommends F connectors should be tightened to a maximum torque of 30 in/lb. A 7/16" torque wrench should be used to prevent over tightening.
Water Proofing Connections 2.6 Water Proofing Connections Many transceiver problems can be attributed to environmental conditions (including vibration), which can loosen cables and permit moisture to penetrate the connectors. It is highly recommended to seal the connectors using a technique similar to the one described below. This will provide moisture protection and keep the connections tight.
Connecting the Power Inserter 2.7 Connecting the Power Inserter WARNING! Always unplug the power supply before making or changing connnections to the power inserter. CAUTION: The power inserter should be installed as near to the building entrance as possible. If this is not possible, then a grounding block for the transceiver cable must be installed at the service entrance.
Aligning the Antenna 2.8 Aligning the Antenna The TR2526+ is equipped with an audible alignment aid that simplifies the setup process. It permits alignment to the hub site without the use of the cable modem or any test equipment. It consists of a level detector for the full receive band and an audible beeper sealed into the unit that sounds at a rate that increases with increasing signal level. The detector operates over a wide signal level range.
