RF400 Series Spread Spectrum Data Radio/Modems
23
c. Select a Radio Address (0 – 1023). The radio addresses must be the
same in point-to-point communications (for point-to-multipoint
communications you could set the base RF400 to 0 and the remotes to
1, 2, 3, etc.).
It is a good idea to label each RF400 indicating the configured
network address, radio address, hopping sequence, etc.
d. Select a Hopping Sequence (0 – 6). The hopping sequence must be
the same for all RF400s in the network.
If there happens to be a neighboring RF400 network using the same
hopping sequence, you should change to a different one in case their
network and radio addresses happen to match yours and to reduce
retries.
- RX LED Test -
To determine if there is a neighboring RF400 network in operation
using the same hopping sequence as yours, stop communications on
your network and observe an RF400 green LED for activity. A
flashing green LED would indicate that there is a nearby network
using the same hopping sequence.
e. Select desired Standby mode (< 24 mA Always on, < 4 mA ½ sec
Cycle, etc.) according to your power budget. All RF400s in the
network must be in the same Standby Mode. The default setting is a
good starting point (< 4 mA ½ sec Cycle).
f. Select desired Retry Level (None, Low, Medium or High) according
to the level of RF ‘collisions’ you expect. This depends on how
many neighboring RF400s in and out of your network and the
frequency of transmissions. Retries can, for example, reduce pauses
in real-time monitoring of Input Locations.
g. Press 9 to “Return to Main Menu”.
h. There are other (“advanced”) parameters which typically remain
“default” or as set by Auto Sense.
i. Press “5” to “Save All Parameters and Exit Setup.”
5.3.2 Remote Station Setup
1. Point-to-point
a. Complete steps 1 to 4 above making the remote station’s Network
Address, Radio Address, and Hopping Sequence the same as the base
station’s.
b. While in Standard Setup verify that the Active Interface configuration
is “Auto Sense” and set the Standby Mode the same as the base
RF400 (default “2” ok).
c. Exit and Save your configuration by pressing “5”.
