A Baud rate of 9600 means that the data istransferred at the rate of 960 characters per second.Example:9600 / 10There are 10 bits to each 8 bit character because each has a start bit anda stop bit.• Data bits are usually 8. There are some devices that you might beinterfacing, such as the Stentofon intercom that use 7 bits, but mostdevices are 8 and 1. (8 for iSTAR controllers, apC panels, and modems. Seethe CCTV switcher documentation to check this setting for your switcher.)• Parity varies. Match with the parity for the modem, iSTAR controller, panel,or switcher.
