6.0 Configuration
This is the RF communications Link Rate. A lower link rate offers
better receive sensitivity performance; a higher link rate, better
throughput. All Nano IP Series in a network must use the same
Link Rate.
The unit address is, and must be, a unique identifier of each
modem in a network.
If the Operation Mode is

presented to the antenna connector at the rear of the Nano IP
Series.
Unless required, the RF Output Power should be set not for
maximum, but rather for the minimum value required to maintain an
adequate system fade margin.
FCC regulations allow
for up to 36dBi effective
isotropic radiated power
(EIRP). The sum (in
dBm) of the transmitted
power, the cabling loss,
and the antenna gain
cannot exceed 36dBi.
This register determines the maximum amount of times that a
packet will be retransmitted (in addition to the initial transmission),
noting the following specific behaviors in various network
topologies:
In a PMP system, set
PMP: Master will retransmit each data packet the exact number of times specified in the Re-
Retransmissions to the
transmissions field; Remote will retransmit only if necessary, and then only until a given packet

is acknowledged or the value of the Remote's Retransmissions field is reached (after which it

PTP: Nano IP Series will retransmit to its counterpart only if necessary, and to a maximum
number of the value specified in its Retransmissions field. Packet is discarded if retransmis-
sions are not successful. Recipients of packets will discard any duplicates.
