Default and
Current
Parameters
The following parameters can be configured for
Default and Current settings:
• Transmit Channel. Channel 0 to 11 (see
Frequency Band Plan on page 19 of this manual).
• Receive Channel. Channel 0 to 11 (see
Frequency Band Plan on page 19 of this manual).
We recommend that transmit and receive channels
be set at least three channels apart.
• Transmit Power. 1 to 10. 1 being the minimum
power level (17 dBm) and 10 being the maximum
power level (26 dBm).
• PN Code. A number between 0 and 999. For
optimal performance this should be “237” (Barker
code for an 11 bit PN sequence).
• Redundancy (A or B). If the hardware
configuration allows (ie. equal gain antennas and
standard power system), the transmit and receive
paths can be swapped. This changes the effective
polarisation’s of the Tx and Rx signals and can be
used to counteract multipath effects. Dual
redundancy can also be used in the event of a RF
transceiver failure.
To configure and program the default parameters, set
the required parameters and then click on the
<Default> button.
To configure and program the current parameters, set
the required parameters and then click on the
<Current> button.
To configure and program the default and current
parameters, set the required parameters and then click
on the <Send All> button.
If the parameters sent to the OU are valid, the relevant
Valid check boxes will be ticked.
