Quatech ExpressCard Serial Adapter User’s Manual 

RS-422/485 Full Duplex (4-wire) 

This mode allows simultaneous transmit and receive operation. 

Transmit and receive data move over separate dedicated pairs of 
conductors in the attached cable.  Each UART's transmit drivers are 

always active in this mode.  The AuxOut/AuxIn signals are also 
available in 4-wire mode. 
 

RS-422/485 Half Duplex (2-wire) Auto-Toggle 

This mode only permits data to flow in one direction at a time.  
Transmit and receive operations share a single pair of conductors in 

the attached cable.  This configuration is often referred to as 

“multidrop.” 

Note:  The Auto-Toggle mode is 

the best choice for most half-

duplex scenarios.  It offers the 
best performance and the best 
ease-of-use. 

The transmit drivers are automatically enabled before data is 

transmitted, then disabled immediately after all data has been 
transmitted.  This feature is implemented in hardware for near-

instantaneous response. 

 

RS-422/485 Half Duplex (2-wire) RTS control 

The half-duplex operation is the same as in the Auto-Toggle mode, 
except that the RTS signal is used to control the transmit drivers 

instead of the automatic control. 
The software application can disable the port's transmit drivers by 
deasserting the UART's RTS output. To allow transmission again, the 

software application must assert the RTS output. 

 

RS-422/485 Half Duplex (2-wire) DTR control 

This mode operates the same as Half Duplex using RTS, except that 

the UART's DTR output is used.
