3.4 Radio Mounting
The radio can be mounted either in a 19-inch equipment rack or on a
table top. It should be located in a relatively clean, dust-free environ-
ment that allows easy access to the rear panel connectors as well as front
panel controls and indicators. Air must be allowed to pass freely over the
ventilation holes and heat sink on the side panel.
The dimensions of LEDR Series radios are:
• 305 mm (12 in) deep
• 426 mm (16.75 in) wide—Excluding rack mounting brackets
• 45 mm (1.75 in) high—1RU
Maximizing RSSI
For newly installed systems, one of the first tasks is to orient the station
antenna for a maximum Received Signal Strength Indication (RSSI) as
shown on the LCD screen. See “Performance” on Page 40 for details. A
maximum RSSI ensures the antenna is properly aimed at the associated
station. Move the antenna slowly while an assistant observes the RSSI
display for a maximum reading. There may be a time delay between
moving the antenna and updating of the RSSI display. Be sure to allow
adequate time between antenna movements and observations.
Attaching the Rack Mounting Brackets
The radio is normally shipped with the rack mounting brackets unin-
stalled. To attach them, select the desired mounting position on the sides
of the chassis. (The brackets may be mounted in one of two locations—
flush with the front panel, or near the middle of the chassis.)
NOTE:
Both short and long screws are provided with the brackets. Use
the long screws for the heatsink (left) side of the chassis and
the short screws for the right side of the chassis. Tighten the
screws securely.
