Note: `Top' and `bottom' positions refer to viewing WT12 Evaluation Kit from top side as seen in Figure 2. Top position must be used when WT12 module is interfaced trough J2 connector. Bottom position is used when WT12 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 WT12. 10 DSR (J5) The DSR button is connected to PIO5 pin on the WT12. 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.

Note: `Top' and `bottom' positions refer to viewing WT12 Evaluation Kit from top side as seen in Figure 2. Top position must be used when external WT12 module's nCTS and RxD pins are interfaced trough J2 connector. Bottom position must be used when WT12 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 Bluegiga Technologies Oy Page 11 of 14 14 RS-232 (J9) DTE interface RS-232 interface PIN configuration is shown in Table 1. The physical interface is D9-male connector (AMP747840-4). PIN Name: No.: I/O: Description: NC 1 NC Not connected RxD 2 I RxD TxD 3 O TxD DTR 4 O DTR on GND 5 GND Ground NC 6 NC Not connected RTS 7 O RTS CTS 8 I CTS NC 9 NC Not connected Table 3: RS232 PIN configuration Bluegiga Technologies Oy Page 12 of 14 15 USB (J10) interface J10 connector is a standard USB B receptacle connector. 16 Power supply (J11) This connector is used with the 5V power supply delivered with the evaluation kit. Diameter 6.0mm, inner pin diameter 2.0mm. 17 Power supply (J12) This connector can be used for external power supply. Power supply must be 5-9V unregulated.
