The only way to tell MUs and RUs apart is by the model number printed on the backside product label. This label also contains the MAC address and serial number of the radio.

Ethernet and Serial Ports

At the bottom of the radio are two access ports: a twist-on weatherproof cable port for RJ-45 Ethernet (and PoE), and an access cover plug for the RJ-11 serial port. Behind the access cover plug are three LEDs that provide RF link-status information. These LEDs are discussed later in this text.

Operational Overview

TrangoLINK-10 MU is a sophisticated broadband wireless device that provides a host of comprehensive tools and functions. The MU typically resides at the managing end of the network and performs all management functions for the associated RU.

In order to establish a wireless link between the MU and the RU, the system administrator must set up the MAC address of the RU in the MU.

When power is first applied to a properly installed RU, it will scan all channel/polarization combinations searching for an MU. Once the RU detects the MU it will stop scanning and lock onto the channel of the MU and begin transmitting using maximum RF power. Before the MU can wirelessly connect to the RU, it must authenticate the RU by verifying the MAC address and performing a ranging operation to the RU.

Upon successfully authenticating and ranging the RU, the MU will adjust the RF transmit power in the RU based on the Target RSSI parameter in the MU. This process is referred to as “power leveling.”

At this point the MU and RU are “associated” and Ethernet traffic will pass over the wireless link.
