 Spread Spectrum Wireless Data Transceiver User Manual 

Preliminary GXM Manual 

Version 0.2 

18 

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. 

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.
