Installation Color Code
With this feature enabled on the AP and SM, operators may install and remotely configure SMs without
having to configure matching color codes between the modules. While the SM is accessible for
configuration from above the AP (for remote provisioning) and below the SM (for local site provisioning), no
user data is passed over the radio link. When using the Installation Color Code feature, ensure that the SM
is configured with the factory default Color Code configuration (Color Code 1 is “0”, Color Code 2-10 set to
“0” and “Disable”). The status of the Installation Color Code can be viewed on the AP Eval web GUI page,
and when the SM is registered using the Installation Color Code the message “
SM is registered via ICC –
Bridging Disabled!
” is displayed in red on every SM GUI page. The Installation Color Code parameter is
configurable without a radio reboot for both the AP and SM. If an SM is registered via Installation Color
Code and the feature is then disabled, operators will need to reboot the SM or force it to reregister (i.e. using
the
Rescan APs
functionality on the AP Eval page).
External Gain Field
An AP, SM, or BH needs to know the gain of its antenna to perform DFS and Auto-TPC (Automatic Transmit
Power Control) (SM only) consistent with regional or national regulations. The GUI includes an
External
Gain
field to support this.
Key points about the
External
Gain
field include:
External Gain is defined as the gain of the antenna minus the loss in the coaxial cable and
connectors.
The External Gain is set on the Configuration => Radio page of each module (AP, SM, BHM, or
BHS)
The default on a 5.4 GHz SM or a unit reset to factory defaults is 17 dB.
The default on a 5.8 GHz SM or a unit reset to factory default is 17 dB
The range is 0 to 35 dB.
A 5.4 GHz SM or BH with an integrated antenna has an External Gain of 17 dB.
The antenna sold with the connectorized 5.4 or 5.8 GHz AP has a gain of 18 dB and cable loss of
approximately 1 dB, giving an External Gain of 17 dB.
A 4.9 GHz SM or BH with an integrated antenna has an External Gain of 17 dB.
The antenna sold with the connectorized 4.9 GHz AP has a gain of 18 dB and cable loss of
approximately 1 dB, giving an External Gain of 17 dB.
Any radio using DFS will use the External Gain to appropriately adjust sensitivity to radar signals.
The use of DFS is determined by the Region Code setting on the Configuration => Home page.
The Auto-TPC used by the PMP 400/430 and PTP 230 Series system takes into account the
External Gain so as not to exceed national or regional EIRP limits.
Procedure for setting the External Gain
If using a BH or SM with an integrated antenna or a connectorized AP with the
connectorized antenna sold with it, leave the
External
Gain
on the Configuration =>
Radio page set to the factory default of
17
dB.
If using another antenna, set the
External
Gain
to the gain of the antenna minus the loss
in coaxial cable and connectors.
IMPORTANT!
Ensure the
External Gain
is set correctly. Setting it low or high can lead to
either a system overly sensitive to DFS events or a system not transmitting
at its full legal power.
