NOTE:
If RF450/RF451/RF452 repeaters will be used, select Endpoint/Repeater as the Radio
Operation Mode for all endpoint/repeaters in the network (that is, radios that are being
used as a repeater but also have a data logger attached). Select Repeater as the Radio
Operation Mode for all standalone repeaters in the network (that is, radios that are
being used only as a repeater without a data logger attached). Select the Repeaters
Used box for all radios in the network.
6. Gateway radio: Using Device Configuration Utility , set the Radio Operation Mode to
Gateway. Set the Network ID to the number decided upon in step 2. Set the Frequency Key
to the number decided upon in step 3. Set the Radio ID to the PakBus Address assigned in
step 1. If the gateway radio will be at computer running
LoggerNet , set the Active Interface
to USB or RS-232 depending on how LoggerNet will be communicating with the
RF451/RF452. Keep the remaining settings at their defaults. (See previous note regarding
repeaters.)
7. Select a data logger or a computer running LoggerNet to be a router. Using Device
Configuration Utility , set this node to beacon. See LoggerNet setup (p. 19). Attach the
gateway radio to this node.
5. Overview
The transceiver (radio) designated as a gateway is able to simultaneously communicate with
numerous endpoints. In its simplest form, the network functions with the gateway broadcasting
its messages to all endpoints, and the endpoints responding to the gateway when given data by
the data logger connected to its data port. See
Figure 5-1 (p. 5).
NOTE:
There may be only one RF451/RF452 or RF450 gateway in a network, and it must be
connected to a PakBus® router. The PakBus router may be software, such as
LoggerNet or
PC400 , or a data logger configured as a router.
