2. To use the evaluation board with HyperTerminal or other terminal program you must first remove the jumpers from pins 7 8 of JP2 if you are using an RS 232 connection to your PC or JP3 if you are using a USB connection to your PC Removing this jumper will disconnect the RTS line from the CMD pin on the module allowing normal operation 5 2 Loopback Mode The RK Wi 232EUR R kit can be operated in a loopback mode by configuring the COM jumpers in such a way as to link together the TXD and RXD lines to and from the module in the remote evaluation board Using this mode the user can send data from their local evaluation board and have it re transmitted back to them by the remote evaluation board The maximum baud rate allowed in loopback mode is 38400 baud for point to point communications only Loopback mode using the RS232 jumpers Figure 5 RS 232 J umpers RK WI 232EUR R USER S MANUAL 6 PCB Layout Diagrams 6 1 RK WI 232EUR R Evaluation Board Layout oQogodoondoudoccca ee e ele J Figure 6 Evaluation Board Layout 12 b 5 SL PERS cocon jeee ee e gt Chapter o e e L N ili H oon e RK WI 232EUR R USER S MANUAL 6 2 WI 232EUR EVM R Evaluation Module Layout Figure 7 Evaluation Module Layout Note Pin 1 of the Wi 232DTS FCC R module s JP2 aligns with Pin 1 of JP6 on the evaluation
