Baud Rate Description
Actual Baud Rate
(selections 0-9)
The actual baud rate for the transceiver’s data port.
It is desirable to set the baud rate to the highest level supported by the device to
which it is connected. In certain circumstances, however, this may actually result
in slower data communications.
Data, Parity
There are six data word length and parity configurations available to be used with
FreeWave transceivers. The default setting is 0 (8, N, 1) and is the most commonly
used serial communications protocol. When Data, Parity are selected from the
Baud Rate menu, a prompt to enter a value for Data, Parity displays. The
following describes each option:
Menu Setting Data Bits Parity Stop Bits
0 8 None 1
1 7 Even 1
2 7 Odd 1
3 8 None 2
4 8 Even 1
5 8 Odd 1
FlowControl
This menu specifies the hardware flow control for the Data port. The options for 0-3
are described below.

2 DTR
3 DOT
Modbus RTU
Support for Modbus RTU protocol is available. The default setting for Modbus
RTU is 0 (Not Enabled).
To enable the Modbus RTU mode:
1. In the Set Baud Rate menu enter (B) and then select 1
2. In the Set MultiPoint Parameters menu, set Master Packet Repeat to 3.
Note: When using the transceiver in Modbus RTU mode, the Master Packet
Repeat must be set to 3 regardless of whether the network is in Point-to-
Point or MultiPoint mode. The Modbus RTU mode must be selected when
transceivers are configured in RS485 or RS422 mode.
