8 PIO SELECT (J3)
This switch toggles PIO2 to PIO7 signal connections between J2 connector and LED/USB/UART interfaces.
Note: ‘Top’ and ‘bottom’ positions refer to viewing WT11 Evaluation Kit from top side as seen in Figure 2.
Top position must be used when WT11 module is interfaced trough J2 connector.
Bottom position is used when WT11 module is interfaced trough the DB9 RS232 connector or if USB
port or if link state LED is used.
J3 Switch top position:
PIO2 connects to pin 3 on the J2 interface
PIO3 connects to pin 4 on the J2 interface
PIO4 connects to pin 5 on the J2 interface
PIO5 connects to pin 6 on the J2 interface
PIO6 connects to pin 7 on the J2 interface
PIO7 connects to pin 8 on the J2 interface
J3 Switch bottom position:
PIO2 connects to USB_IO1
PIO3 connects to nDTR-UART
PIO4 connects to nCD-UART
PIO5 connects to nDSR-MUX
PIO6 connects to VBUS
PIO7 connects to blue LED on the board marked with PIO7
9 RESET (J4)
The RESET button resets the module using the reset pin on the WT11.
10 DSR (J5)
The DSR button is connected to PIO5 pin on the WT11. Thus, when you want to use the DSR signal, please
refer to the iWRAP 2.1.0 manual. The use of DSR signal is described under SET CONTROL ESCAPE
chapter.

11 Speaker JACK (J6)
Connect your generic PC headset’s 3,5mm speaker plug here.
12 Microphone JACK (J7)
Connect your generic PC headset’s 3,5mm headphone plug here.
13 SIG Select (J8)
This switch toggles nCTS and RxD signals connection between J2 connector and DB9 RS232 connector.
Note: ‘Top’ and ‘bottom’ positions refer to viewing WT11 Evaluation Kit from top side as seen in Figure 2.
Top position must be used when external WT11 module’s nCTS and RxD pins are interfaced trough
J2 connector.
Bottom position must be used when WT11 is interfaced trough the DB9 RS232 connector.
J8 Switch top position:
nCTS connects to pin 10 on the GPIO (J2) interface
RxD connects to pin 14 on the GPIO (J2) interface
J8 Switch bottom position:
nCTS connects to nCTS-UART
RxD connects to RXD-UART
