Select the Baud Rate
Genius bus communications can occur at any of four baud rates: 153.6 Kbaud
standard, 153.6 Kbaud extended, 76.8 Kbaud, or 38.4 Kbaud. The default is 153.6 K
baud (standard). The Genius I/O System User’s Manual gives guidelines for baud rate
selection.
Each device’s communications baud rate must be the same as that used by all other devices on the
bus, or the bus will not operate.
