Setting up a Transceiver
Operation Mode
The Operation Mode option designates the method FreeWave transceivers use to communicate with
each other. FreeWave transceivers operate in a Master to Slave configuration. Before the transceivers
can operate together, they must be set up to properly communicate.
In a Point-to-Point configuration, Master or Slave Mode may be used on either end of the communication
link without performance degradation. When setting up the transceiver, remember that a number of
parameters are controlled by the settings in the Master. Therefore, deploying the Master on the
communications end where it will be easier to access is advised, but not necessary.

Mode
Description
Point-to-Point
Master (0)
This mode designates the transceiver as the Master in Point-to-Point mode. The
Master may call any or all Slaves designated in its Call Book.
In Point-to-Point mode the Master determines the setting used for most of the
radio transmission characteristics, regardless of the settings in the Slave. The
settings not determined by the Master are: RF Xmit Power, Slave Security, Retry
Time Out, and the Hop Table settings.
A quick method of identifying a Master is to power the transceiver. Prior to
establishing a communication link with a Slave, all three of the Master’s LEDs
will be solid red.
Point-to-Point
Slave (1)
This mode designates the transceiver as a Slave in Point-to-Point mode. The
Slave communicates with any Master in its Call Book.
When functioning as a Slave, the
Entry to Call
feature in the transceiver’s Call
Book is not operational. The Call Book may be bypassed in the Slave by setting
Slave Security to 1. See the Slave Security section later in this manual.
Point–to-
MultiPoint
Master (2)
This mode designates the transceiver as a Master in MultiPoint mode. This
mode allows one Master transceiver to simultaneously be in communication with
numerous Slaves.
A Point-to-MultiPoint Master communicates only with other transceivers
designated as Point-to-MultiPoint Slaves.
Point-to-
MultiPoint
This mode designates the transceiver as a Slave in MultiPoint mode. This mode
allows the Slave to communicate with a MultiPoint Master. The Slave may
