a. Baud rates higher than 115,200 bps are not supported by standard PC hardware. Special PC hardware may be required
for higher rates, including 230400 bps, 460800 bps and 921600 bps. See
OEM6 Card Default Serial Port Configurations
on page 39 for details.
b. Upon power-up, COM3 is enabled by default. COM3 is multiplexed with Event 2 and GPIOH(0)
c. To enable EVENT2, issue the following commands:
INTERFACEMODE COM3 NONE NONE
MARKCONTROL MARK2 ENABLE
d. CAN Bus behavior must be asserted through the NovAtel API software. See
CAN Bus (not available on the FlexPak6D)
page 74 for further details. See also
