LongSpan 900-MHz Wireless Ethernet Tube Housing Kit
• Choose an 8-digit hex (0–9 and A–F) Network Name that will be common
among the AP and the SUs and enter it. The hyphen is required.
• Choose a 32-digit hex Encryption Key and enter it. Again, the hyphens are
required. This key must match between the AP and the SU. Write down the key.
After entering the parameters, click the “Apply” button to save them to the
radio.
9. When all the radios are keyed and operating, connect them to your network
and Ethernet devices as desired and cycle the radio’s power to begin normal
operation. You can manage the SUs via a browser over the wireless network.
NOTE: Do not plug actively linked radios into the same switch because this will
corrupt its routing table and may cause network problems just as if you
plugged a CAT5 cable directly between two ports of a switch.
5.2 Physical Setup
1. Before mounting the radio in its final location, follow the digital setup
instructions in Section 5.1.
2. Mount the radio securely. Maximize lightning resistance by providing a strong
DC ground connection to the metal housing.
3. Connect the radio’s TNC RF connector to a suitable antenna. A simple omni-
directional dipole unit is included—you can use this antenna for testing and for
relatively undemanding applications. If your application requires greater distance
and/or a wider range of direction, choose either the LongSpan Long-Distance
900-MHz Directional 15-dBi Yagi antenna (LS900-15Y) or the LongSpan
Medium-Range 900-MHz Omnidirectional 5-dBi antenna (LS900-5M).
4. The unit receives power via an Ethernet cable, so you can place the power
supply in a convenient location. The included Power over Ethernet injector (PoE)
enables you to add DC power to unused wires in the cable. Decide where to
place the PoE based on its proximity to AC power at some point along the
desired path of the Ethernet cable. Plug the included power supply into an
appropriate electrical outlet and into the PoE. Connect an Ethernet cable
between your network and the “DATA IN” port on the PoE. Connect a second
cable from the “P + DATA OUT” port on the PoE and the radio. The radio has a
cable clamping device that allows an RJ-45 plug on the cable to pass through it.
