Baud Rate Setting
The DeviceNet baud rate is set using the DIP switch on the front of the NE1A-
series Controller. The baud rates settings are shown in the following table:
Note
The baud rate is set to 125 kbit/s at the factory.
Software Setting
The Network Configurator can be used to set the baud rate. The procedure is
as follows:
1. Turn OFF the power and change the DIP switch to the "software setting."
2. Turn ON the power. When power is turned ON, the NE1A-series Controller
will operate at the previous baud rate (default setting: 125 kbit/s).
3. Reset to the default settings using the Network Configurator’s RESET
command.
The configuration information held in the device will be initialized.
4. Set the baud rate from the Network Configurator.
5. Reset the NE1A-series Controller by cycling the power or using the NE1A-
series Controller RESET command from the Network Configurator. The
NE1A-series Controller will then operate with the baud rate set from the
Network Configurator, i.e., the software setting.
Automatic Baud Rate Detection
The NE1A-series Controller’s baud rate can be set automatically to match the
baud rate of the master on the network. The baud rate must be set in at least
one Safety Master or Standard Master on the network. After turning ON the
power, the baud rate is set when establishing communications, and the baud
rate setting is stored until the next time power is turned ON.
IMPORTANT
• Turn OFF power to the NE1A-series Controller before setting the DIP
switch.
• Do not change the DIP switch setting while the power supply is ON. The
NE1A-series Controller will detect this as a change in the configuration
and will switch to ABORT State.
• The baud rate must be the same for all nodes (masters and slaves) on the
network.
