2.1 Familiarizing Yourself with the EX-5r
The EX-5r utilizes time division duplex (TDD) radio transmission. That is, that the transmitted
signal in both directions is using the same center frequency and is transmitting in one direction
for a period of time, then transmitting in the opposite direction for another period of time. This
total period of time is referred to as the “Frame Length” or “TDD Frame Length”, and is further
discussed in section 2.4.
The two radio terminals are identical hardware to one another, except for this configuration
setting in software. When the radios are in their default state (such as they are when they are
initially shipped), both radios are configured as Radio B. One end of the link must be
configured as Radio A before the two ends of the radio system will communicate. It can be
considered that Radio A is the primary radio of the link. Radio A provides the master clocking
and control to Radio B. For most applications, it is not important how the radio link is oriented,
only that one end is configured for Radio A, and the other for Radio B. For some applications,
such as multi-radio hub sites or repeaters, the orientation of the radio systems may be more
critical. Details about link orientation can be found in section 2.5.
There are two means to configure the radios for Radio A/B determination:
1) Using the browser-based graphical user interface (GUI)
2) Using Telnet command line interface (CLI)
It is encouraged to use the browser-based GUI for radio configuration, as there are many settings
that will be necessary to adjust the device to meet your operational needs, and the GUI is a very
intuitive interface. This interface requires a computer with an Ethernet port and web browser
software, such as Microsoft Internet Explorer 5.0 or above. See section 5.2 for details on how to
connect to and use the browser-based GUI interface.
2.1.1 Shipping Box Contents
Unless purchased as a spare terminal, the EX-5r is shipped as a complete ‘hop’ (radio link pair
consisting of two terminals). An outer box has labeling that indicates the contents of the box,
with the part number and serial number details for both radio terminals.
Inside the outer box are two identical boxes, each of these boxes is also marked with the part
number and serial number of the individual terminal contained inside the box. The terminal box
has the following items inside:
• Radio terminal (configured for Radio B)
• AC adapter
• DC injector
• Pole mounting kit
• Pre-terminated Ethernet/Power Cable (50 ft. each)
