Installation and Start-up
MVME197LEIG/D1 3-3
3
Caution
Inserting or removing modules while power is applied
could damage module components.
1. Turn all equipment power OFF. Refer to the Hardware Preparation and
Installation chapter in this manual for selecting the configuration switch
settings required for the user’s particular application.
2. Refer to the set-up procedure for the user’s particular chassis or system for
details concerning the installation of the MVME197LE.
3. Connect the terminal which is to be used as the 197Bug system console to
the default debug EIA-232-D port at serial port 1 on backplane connector
P2 through an MVME712X transition module. Refer to the MVME197LE,
MVME197DP, and MVME197SP 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 the MVME197LE 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 197Bug debugger.
Note
In order for high-baud rate serial communication between
197Bug 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 the user gets garbled messages
and missing characters, then the user should check the
terminal to make sure XON/XOFF handshaking is enabled.
4. If it is desired 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 MVME712X transition module), connect the
appropriate cables and configure the port(s) as detailed in step 3 above.
After power-up, this(these) port(s) can be reconfigured by programming
the MVME197LE CD2401 Serial Controller Chip (SCC), or by using the
197Bug PF command.
