- Modbus RTU Timing
- The Modbus RTU setting causes the radio to wait for an amount of time, “gathering” data before sending out the radio link.
- With a setting of 0 (Disabled), the radio will send data out its radio link as soon as the data is received into the serial port.
- With a setting of 1, the radio will wait for a number of slots equal to 2 times the Master Packet Repeat setting before sending the received data out the radio link. For example, if Master Packet Repeat = 3, the radio will wait for 6 slots, gathering ...
- With a setting of 2 and higher, the radio will wait for a number of slots calculated by the following formula:
- (Modbus RTU Setting + Master Packet Repeat Setting + 1) x 2
- For example, in a radio where the Modbus RTU setting = 2 and the Master Packet Repeat setting = 3, the radio will wait for (2+3+1) x 2, or 12 slots.

Point-to-Point
Repeater (5)
FreeWave allows the use of one repeater 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 FreeWave's user interface may be
changed either directly with a program such as Windows Terminal 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.
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.
