2.2 SETTING BIT RATE
The Addressable Bus Converter has a default bit rate of 115,200 bits per second.
However, the Converter supports changing the bit rate, depending on the
sensors connected to the RS-485 bus. The TTL, USB, and RS-485 bit rates are all
updated automatically when a connection is opened to a USB host.
Note: The bit rate MUST be set using a USB connection. A bit rate change
cannot be done over a TTL connection.
2.2.1 USING USB HOST SOFTWARE
To change the bit rate, do the following:
1.
Connect the USB cable to the USB port on the Converter.
2.
Start the host software on the PC.
3.
Set the desired bit rate in the settings of the host program.
4.
Open the connection.
The software will write the new bit rate to the Converter's non-volatile memory.
The new bit rate will serve as the default bit rate after the next power-up.
