Baud Rate

The following table lists standard baud rates for Serial port instruments. Baud rates may be changed using the Device Driver. Note: Some instruments use a virtual COM port even though they have an alternate connection. For example, Models DI-145, DI-149, DI-155, DI-245, DI-148U and DI-158U devices use a virtual COM port. See Virtual COM ports for more information.
