Once the connection to the PC is made, power may be applied to the PC and the terminal emulation
software can be run. In terminal mode, it is necessary to select the baud rate and character format for the
channel. Most terminal emulation software packages provide a command known as “Alt-p” (press the p
key while pressing the Alt key) to choose the baud rate and character format. The character format should
be 8 bits, no parity, one stop bit. (See
Section 1.6.5, “Terminal Character Format
.”) The baud rate should
be set to 115200. Power can now be applied to the board.
Pin assignments are as follows:
1. Data Carrier Detect—Output (shorted to pins 4 and 6)
2. Receive Data—Output from board (Receive refers to terminal side.)
3. Transmit Data—Input to board (Transmit refers to terminal side.)
4. Data Terminal Ready—Input (shorted to pin 1 and 6)
5. Signal Ground
6. Data Set Ready—Output (shorted to pins 1 and 4)
7. Request to Send—Input
8. Clear to Send—Output
9. Not connected
