Module Serial Port 0-1/CAN Bus
The conga-MEVAL provides the module’s serial port 0 (SER0) on pin header X115 and the module’s serial port 1 (SER1) on pin header X116 or
CAN bus connector X109. The serial ports support only RS-232 signals, without flow control.
Use jumper X111 to route the module’s serial port 1 to pin header X116 or to CAN bus connector X109. Use jumper X110 to set the CAN bus
mode.
