Making external connections Quatech ExpressCard Serial Adapter User’s Manual
Making external connections
Quatech Serial Adapters are equipped with male DB-9 connectors for
RS-232 and with female DB-9 connectors for RS-422/485. The
following figures and tables show the serial port pinouts for RS-232
and RS-422/485 applications.
RS-232 serial connections
RS-232 devices are classified by their function as either Data
Terminal Equipment (DTE) or Data Communication Equipment
(DCE).
Note: A DTE device is the
communication source. A DCE
device provides a communication
channel between two DTE-type
devices.
Note: In many applications,
DCEs are unnecessary. This
allows you to use a null modem
cable (modem eliminator cable)
to directly connect two DTEtype devices.
Figure 15 illustrates the RS232 pinouts for typical DTEto-DCE and DTE-to-DTE
cables with 9-pin connectors.
Figure 14 - Use of DTEs and DCEs in a communication link
DTE- and DCE-type devices have complementary pinouts that allow
terminals and modems to connect directly using a one-to-one cable as
shown in Figure 15. Two DTE-type devices can be connected by a
null modem cable. A typical null modem cable is also shown in the
figure.

Quatech Serial Adapters are DTE devices that connect to peripheral

Note: Please refer to Setting
Advanced Options in the
section on Using Device
Manager for details on
software-selectable advanced
options for RS-422/485.
Quatech Serial Adapters provide four differential communication
signals (either RS-422 or RS-485) per channel. Transmit Data (TxD)
and Auxiliary Output (AuxOut) are the two output signals. Receive
Data (RxD) and Auxiliary Input (AuxIn) are the two input signals.
The adapters also provide a ground signal.
The AuxOut pair can carry the UART’s RTS signal. The AuxIn pair
can carry the UART’s CTS signal. Alternatively, the AuxOut pair can
be configured to internally loopback to the AuxIn pair, with the
UART’s RTS signal also looped back to its CTS signal. The signals
are available to connect to peripheral devices through a female DB-9
connector. The following table shows the RS-422/485 connector
definitions.

Setting advanced options
The Serial port advanced properties can be altered from the Device
Manager window. Options for each serial port can be individually
controlled.
Changes are applied:
• To all serial ports when the Serial Adapter is unplugged from
the ExpressCard slot and plugged back in,
OR
• To a single port the next time an application opens the serial
port.
• If an application already has a port open, it must be closed
and re-opened for the changes to take affect.

Figure 25 - Windows XP Device Manager - Serial Port, RS-422/485 tab
Rev 1.00 (July 2007) Page 25
Using configuration utilities 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
Note: The Auto-Toggle mode is
the best choice for most halfduplex scenarios. It offers the
best performance and the best
ease-of-use.
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.”
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 nearinstantaneous 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.
Page 26 Rev 1.00 (July 2007)
Quatech ExpressCard Serial Adapter User’s Manual Using configuration utilities
Receiver Control (RS-422/485 adapters only)
In RS-422/485 half-duplex operating modes, the serial port’s receivers
can be set to be active all the time or to be active only when the port
is not transmitting. The desired choice is selected from the dropdown
box.
Always (default)
Select this option to force the receivers to be active all the time. This
selection will cause the receiver to hear the echo of whatever the
serial port transmits.
Only when not transmitting
This selection is useful for scenarios where the serial port should not
hear the echo of its own transmissions. The receivers will be disabled
whenever the serial port transmits data.
Connector Set-up : AuxOut/AuxIn (RS-422/485 adapters only)
This setting determines which signals are routed to the AuxIn and
AuxOut pins of the serial port connectors. Regardless of which setting
is chosen, each UART's DTR output is internally looped back to its
own DSR, DCD, and RI inputs.
Loopback (default)
Select this choice when only transmit and receive data signaling is
required.
¾ Each UART's RTS output is internally looped back to its CTS
input.
¾ Each port's AuxIn signal pair is looped back to its AuxOut
signal pair at the connector.
Modem Control
Select this choice when hardware flow control is required.
¾ Each UART's RTS output and CTS input are routed to the
AuxOut and AuxIn signal pairs, respectively.
Clocks

Select this choice when it is necessary to connect together two ports
at different baud rates. In order to properly function, both ports must
support and have the feature enabled.
¾ Each UART's RTS output and CTS input are looped back
together.
¾ The UART’s transmit clock (TClk) is fed out to the AuxOut
line.
¾ The UART’s receive clock (RClk) is fed in from the AuxIn line.
