Set the Data Rate Switches
for Channels 1 and 2 To set the DeviceNet data rate switches for Channels 1 and 2:
1. Locate the switchbank labeled “Channel 1” on the left side of the
module.
2. Use the table below to determine the data rate you want to set
for “Channel 1.” Record your choice in the fourth column.
3. Using a ball point pen or similar object, adjust switches 2 and 1
to your desired data rate setting. (NOTE: Do not use a pencil
to adjust switches. The lead may break off in the
switchbank.) Slide the switches up to denote an on or “1”
position. Slide the switches down to denote an off or “0”
position.
For example, if you want to set DeviceNet data rate of 500K baud for
Channel 1, then you set switch 2 to an off or “0” position and switch 1
to an on or “1” position.
4. Repeat steps 1-3 to set the DeviceNet data rate for Channel 2,
using the switchbank labeled “Channel 2’. Adjust the switches to
your desired data rate setting.
Set the I/O Chassis
