For serial ports (COM1, COM2 and COM3), data rates higher than 115200 bit/s are not supported by standard PC hardware. Special computer hardware may be required for higher rates, including 230400 bit/s and 460800 bit/s. |

CAN1 Rx and Tx signals are internally multiplexed with VARF and EVENT2, respectively. Both VARF and EVENT2 are enabled by default. To enable CAN functionality, the following commands must be issued before configuring the CAN1 port: EVENTOUTCONTROL MARK1 DISABLE EVENTINCONTROL MARK2 DISABLE These commands, together with the commands to configure the CAN1 port, can be saved using SAVECONFIG. |
