EIA/TIA−449 Speed and Distance Limitations
The use of balanced drivers allows EIA/TIA−449 signals to travel greater distances than the EIA/TIA−232
standard. The table below lists the standard relationship between baud rate and maximum distance for
EIA/TIA−449 signals. These limits are also valid for V.35 and X.21.
Data Rate (Baud)
Distance (Feet)
Distance (Meters)
2400
4,100
1,250
