Ranging Mode
During installation, the wireless units perform “Automatic Ranging”. The ranging
mode allows the installer to control the behavior of the system’s automatic ranging
algorithms. The default value is 0 to 40 km (0 to 25 miles). If the installer is required
to install a link of greater than 40 km (25 miles) then the ranging mode attribute
MUST be configured to ‘0 to 100km’ (0 to 62 miles) or ‘0 to 200km’ (0 to 124 miles)
mode depending on the range of the link.
NOTE
If preferred, range functions can be configured to operate in miles, as described
in Properties on
page 6-131.
Target Range
Installers that know the range between the two wireless units to within ± 1 km can use
the target range mode. The main advantage of the target range mode is that it reduces
the time taken by the units to range. To use the target range mode the installer MUST
select Target Range as the ranging mode and enter the approximate range in km in
the Target range data entry field at both ends of the link.
Platform Variant
Chooses between an integrated unit or a connectorized unit that requires an external
antenna.
Frequency Band
Only displayed for the PTP 25600 frequency variant, which operates in one of three
bands as described in Variable channel bandwidth operation on

o Middle: 2572 MHz to 2614 MHz
o Upper: 2624 MHz to 2690 MHz
Channel Bandwidth
Users can choose a variable channel bandwidth for the available spectrum. The
selection depends upon the frequency variant and region. For more information, see
