PRELIMINARY
Operation 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 Slaves designated in its Call Book.
In Point-to-Point mode the Master determines the settings used for most of the
radio transmission characteristics, regardless of the settings in the Slave and/or
Repeaters. The settings not determined by the Master are: RF Xmit Power,
Slave Security, Retry Time Out, and the Hop Table settings.
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—either directly or through
up to four Repeaters.
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 communicate simultaneously with
numerous Slaves and Repeaters.
A Point-to-MultiPoint Master communicates only with other transceivers
designated as Point-to-MultiPoint Slaves or Point-to-MultiPoint Repeaters.
Point-to-
MultiPoint Slave
(3)
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
communicate with its Master through one or more Repeaters.
Point-to-Point
Slave/Repeater
(4)
This mode designates the transceiver to act as either a Slave or Repeater—
depending on the instructions from the Master. The transceiver cannot act as
both a Slave and a Repeater at the same time. True Slave/Repeater functionality
is only available in a MultiPoint mode.
Note: Repeaters have no security features. When a transceiver is designated
a Point-to-Point Slave/Repeater, any Master may use it as a Repeater.
Point-to-Point
Repeater (5)
FreeWave allows the use of up to four Repeaters in a Point-to-Point
communications link, significantly extending the operating range. When
designated as a Repeater, a transceiver behaves as a pass-through link. All
settings for the call book, baud rates and radio transmission characteristics are
disabled. A Repeater will connect with any Master that calls it. The Repeater
must be set up properly in the Master's call book.
Point-to-Point
Slave/Master
Switchable (6)
Mode 6 allows the transceiver to be controlled entirely through software
commands. A number of key parameters in the user interface may be changed
either directly (with a program such as HyperTerminal) or through the use of
script files. Additionally, when the Point-to-Point Slave/Master Switchable option
is selected and the transceiver is not calling a Slave, it will function as a Slave
and accept any appropriate calls from other transceivers. See Application note
#5476 “Mode 6” to use Mode 6.
Point-to-
MultiPoint
Repeater (7)
This option allows the transceiver to operate as a Repeater in a MultiPoint
network. See the MultiPoint parameters section for details on enabling
MultiPoint Slave/Repeater mode.
Mirrorbit
Master(A)
Mirorbit Slave (B)
See FreeWave Application note #5424 “SEL Mirrored Bits Comm” for information
on Mirrored Bit Communication.
Ethernet Options
(F)
This menu is not utilized in the GXM.
