Setting the Data Rate

DIP switches 7 and 8 set the data rate at which the RediSTATION
communicates on the DeviceNet network. The factory default
setting is 125K BPS.

DeviceNet Data Rate

00 = 125K BPS
01 = 250K BPS
10 = 500K BPS
11 = Unused

Default Configuration

OFF = 0

ON = 1

The data rate determines the maximum length of the DeviceNet
cable.

Data Rate

Cable Length (Maximum)

125K BPS

500 meters (1600 feet)

250K BPS

200 meters (600 feet)

500K BPS

100 meters (300 feet)

To set the DeviceNet data rate:

1. Refer to the table above to select the correct data rate.

2. Slide switches 7 and 8 to the appropriate ON/OFF positions.
