3. Refer to the set-up procedure for your particular chassis or system for 
details concerning the installation of the MVME166. 
4. Connect the terminal which is to be used as the 166Bug system console to 
the default debug EIA-232-D port at serial port 1 on front panel I/O 
connector J9 through an MVME712-10 or MVME712-06 transition module. 
Refer to the MVME166/MVME167/MVME187 Single Board Computers 
Programmer’s Reference Guide for some possible connection diagrams. Set 
up the terminal as follows: 
– eight bits per character 
– one stop bit per character 
– parity disabled (no parity) 
– baud rate 9600 baud (default baud rate of MVME166 ports at power-
up) 
After power-up, the baud rate of the debug port can be reconfigured by 
using the Port Format (PF) command of the 166Bug debugger. 
Note
In order for high-baud rate serial communication between
166Bug and the terminal to work, the terminal must do some
form of handshaking. If the terminal being used does not
do hardware handshaking via the CTS line, then it must do
XON/XOFF handshaking. If you get garbled messages and
missing characters, then you should check the terminal to
make sure XON/XOFF handshaking is enabled.
5. If you want to connect devices (such as a host computer system and/or a 
serial printer) to the other EIA-232-D port connectors (marked SERIAL 
PORTS 2, 3, and 4 on the MVME712-10 or MVME712-06 transition 
module), connect the appropriate cables and configure the port(s) as 
detailed in step 4. above. After power-up, this(these) port(s) can be 
reconfigured by programming the MVME166 CD2401 Serial Controller 
Chip (SCC), or by using the 166Bug PF command. 
Note that the MVME166 also contains a parallel port. To use a parallel 
device, such as a printer, with the MVME166, connect it to the 
PRINTER/PARALLEL port on an MVME712-10 or MVME712-07 
transition module. Refer to the MVME166/MVME167/MVME187 Single 
Board Computers Programmer’s Reference Guide for some possible 
connection diagrams. However, you could also use a module such as the 
MVME335 for a parallel port connection.
