Other parameters commonly needing review or adjustment are:
• RF Output Power Level (AP Only)—Check and adjust as neces-
sary for compliance with regulatory limits. (Default power is
+30 dBm for 900 model, +20 dBm for 3650 model.) Note that
Remotes “auto-adjust” power output based on target receive
signal set at the Access Point.
• Password —Used for remote access and Menu System features.
• Frequency Mode (900 model only)—This is found under Radio
Configuration Menu>Frequency Control . The following modes
are available:
Single Channel —Where AP and Remote link up using one fre-
quency channel of the 14 possible channels in the 900 Mhz
band. This is the default frequency mode.
Static Hopping —Where an AP and Remote link up using
FHSS based on a Hop Pattern.
Hopping with Hand-offs —(Used with Remotes only.) Based on
AP locations file, which contains GPS coordinates to prede-
termine or preselect which AP to hop with.
• Frequency (3650 model only)—Operating frequency in MHz.
• TDD Sync Mode (AP only)—Selections are: Free Run , Prefer
GPS , and GPS Required .
For single channel operation, the TDD Sync Mode can be set to
Free Run or GPS Required . Using GPS Required synchronizes
the AP’s transmissions to the GPS timing. When the frequency
mode is
Static Hopping the TDD Sync Mode must be set to GPS
Required .
Free Run allows for rapid configuration in most systems. Note
that Free Run only works on single channel frequency mode (the
default mode).
GPS Required is only needed on the 3650 model to synchronize
multiple Access Points.
NOTE: The default password for all units is admin . The default user-
name is admin .
A unique IP address and subnet are required to access the Menu
System, either through the
LAN port, or remotely over-the-air.
A summary of selected operating parameters’ range and default values
is included in the Installation Setup Chart at the center of this guide.
