CONFIGURATION AND SETUP
68EVB912B32UM/D 2-4
2.5 TERMINAL COMMUNICATIONS SETUP
2.5.1 Communication Parameters
The EVB’s serial communications port uses the communication parameters listed in Table 2-3.
Of these, only the baud rate can be changed. For instructions on changing it, refer to 2.5.4
Changing the Baud Rate.
Table 2-3. Communication Parameters
Baud Rate 9600
Data Bits 8
Stop Bits
1
Parity
none
2.5.2 Dumb-Terminal Setup
Configuring a dumb terminal for use with the EVB consists of setting its parameters as shown in
Table 2-3. Many terminals are configurable with externally accessible switches, but the
procedure differs between brands and models. Consult the manufacturer’s instructions for the
terminal being used.
2.5.3 Host-Computer Setup
One advantage of using a host computer as the EVB’s terminal is the ability to generate code off-
board, for subsequent loading into the EVB’s memory. It is thus desirable for the host to be
capable of running programs such as P&E Microcomputer Systems' IASM12 or Motorola’s
MCUasm assembler. For more information, refer to 3.7 Off-Board Code Generation.
To serve as the EVB’s terminal, the host computer must have an RS-232C serial port and an
installed communications program capable of operating with the parameters listed in Table 2-3.
Setting up the parameters is normally done within the communications program, after it has been
started on the host. Usually, the setup can be saved in a configuration file so that it does not have
to be repeated. Procedures vary between programs; consult the user’s guide for the specific
program.
