Motorola MVME2400 manual Debug Port, MVME240x

	MVME240x
DEBUG Port	2

The RJ45 port labeled DEBUG on the front panel of the MVME240x supplies the MVME240x serial communications interface, implemented via a UART PC16550 controller chip from National Semiconductor. It is asynchronous only. This serial port is configured for EIA-232-D DTE, as shown in Figure 2-1.

The DEBUG port may be used for connecting a terminal to the MVME240x to serve as the firmware console for the factory installed debugger, PPCBug. The port is configured as follows:

❏8 bits per character

❏1 stop bit per character

❏Parity disabled (no parity)

❏Baud rate = 9600 baud (default baud rate at power-up)

After power-up, the baud rate of the DEBUG port can be reconfigured by using the debugger’s Port Format ( PF) command. Refer to Chapters 5 and 6 for information about PPCBug.
