Network features like High Priority using DiffServ, MIR, CIR, NAT, DHCP and VLAN are available for the
PMP 400/430 and PTP 200/230 Series OFDM radios, and are configured in the same way as they are for
the PMP 100 Series and PTP 100 Series radios.
In the 5.4 and 5.8 GHz band, DFS (Dynamic Frequency Selection) is provided for regulatory compliant
operation, and is activated (if required per regulatory rules) using the “Region Code” feature. Two alternate
frequencies can be configured to provide service in the unlikely case a module detects radar and triggers
DFS, the same as standard Canopy. “External Antenna Gain” may need to be configured consistent with
any antennas used, to avoid making the system overly sensitive to radar detection. “Whitening,” a technique
used to avoid self-interference on Canopy FSK radios, is not offered as an option on the PMP 400/430 and
PTP 200/230 Series radios, as whitening is not a technology applicable to an OFDM signal.
Power and Grounding
PMP 430 Series APs and PTP 230 BHs use a nominal 56 VDC power system with power on pins 5 and 8
and return on pins 4 and 7. PMP 430 Series APs must use a CMM4 with a 56 VDC power supply. A
CMMmicro will not power these units as it is providing the wrong voltage on the wrong pins. PMP 430 Series
SMs use a 29.5 VDC wall mount power supply.
PMP 54400 APs and SMs and PTP 54200 BHs use a nominal 30 VDC power system with power on pins 7
and 8 and return on pins 4 and 5. PMP 54400 APs and PTP 54200 BHs can be powered from either a
CMMmicro with a 30 VDC power supply or a CMM4 with a 30 VDC power supply. A 29.5 VDC wall mount
power supply is available for PMP 54400 SMs.
PMP 49400 APs and SMs and PTP 49200 BHs use a nominal 56 VDC power system with power on pins 5
and 8 and return on pins 4 and 7. PMP 49400 APs and PTP 49200 BHs must use a CMM4 with a 56 VDC
power supply. A CMMmicro will not power these units as it is providing the wrong voltage on the wrong pins.
A 56 VDC power supply is available for PMP 49400 SMs.
IMPORTANT!
When working on sites with both power systems, use care not to wrongly
mix power supplies and radios as the two power systems use different
pinouts as well as different voltages.
On sites with a mix of 30 VDC and 56 VDC radios (up to the limit of 8 radios supported by one CMM4), a
CMM4 connected to both a 30 VDC power supply and a 56 VDC power supply can be used.
Due to the full metallic connection to the tower or support structure through the AP’s antenna or a
connectorized BH’s antenna, grounding the AP or BH and installing a 600SSH surge suppressor within 3 ft
(1 m) of the AP or BH (see
Figure 14
) is strongly recommended to suppress over voltages and over
currents, such as those caused by near-miss lightning. APs and BHs provide a grounding lug, as shown in
Figure 16
, for grounding to the tower or support structure.
