terminal. A number of baud rates can be programmed. On power-up or manual RESET, the dBUG ROM
monitor firmware configures the channel for 19200 baud. Once the dBUG ROM monitor is running, a SET
command may be issued to select any baud rate supported by the ROM monitor. Refer to
“Using the Monitor/Debug Firmware,”
1.8.5
The character format of the communication channel is fixed at power-up or RESET. The default character
format is 8 bits per character, no parity and one stop bit with no flow control. It is neccessary to ensure
that the terminal or PC is set to this format.
1.8.6
The board is now ready to be connected to a PC/terminal. Use the RS232 serial cable to connect the
PC/terminal to the M5249C3 PCB. The cable has a 9-pin female D-sub terminal connector at one end and
a 9-pin male D-sub connector at the other end. Connect the 9-pin male connector to connector P3 on the
M5249C3 board. Connect the 9-pin female connector to one of the available serial communication
channels normally referred to as COM1 (COM2, etc.) on the PC running terminal emulation software. The
connector on the PC/terminal may be either male 25-pin or 9-pin. It may be neccessary to obtain a
25pin-to-9pin adapter to make this connection. If an adapter is required, refer to
the pin assignment for the 9-pin connector on the board.
1.8.7
A personal computer may be used as a terminal provided a terminal emulation software package is
available. Examples of this software are PROCOMM, KERMIT, QMODEM, Windows 95/98/2000 Hyper
Terminal or similar packages. The board should then be connected as described in
“Connecting the Terminal.”
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 neccessary 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
should be set to 19200. 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).
