ETHERNET
Physical Layer 10/100BASE-T
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 Section 3, OEM6 Card
Default Serial Port Configurations on page 31 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 Section 4.7.2, CAN Bus on page
63 for further details. See also Figure 61, Top-view, P1500 Main Connector 24-Pin Header on Page 130
