Serial Interface (RS-232) 

The MB-COME6-4 supports two RS232 serial ports at the on board connector 

−

 

Connector type: 

Molex 53398-1071 

−

 

Mating connector: 

Molex 51021-1000 crimp housing 

 
The COM Express™ Specification does only provide signal definitions for RX and TX lines for the serial interface. Due to the TQ-

flexiCFG feature, the serial ports can be configured to route the handshake signals to free pins on the COM Express connector.

The four COM Express™ serial signals (RX/TX) are specified to provide a protection and level shifter circuit.  
The implementation of this circuit would result in a lower transfer speed on the two serial ports of the COM Express™ module. 
On the MB-COME6-4 the protection circuit is removed and the serial ports provide a transfer rate of up to 115 kbaud. 

The MB-COME6-4 can only be used in combination with Type 6 pinout COM Express™ modules.

1:  These signals are not specified in COM Express™ specification.  

These signals are only available when the TQ flexiCFG feature is available on the COM Express™ module. TQ modules support this feature. 

2:  Not available since signal is not defined in COM Express™ specification. 
3:       Only available when the TQ flexiCFG feature is available on the COM Express™ module.
