Installation and Startup
MVME162IG/D2 3-5
3
4. Jumpers on headers J11 and J12 configure serial ports 1 and 2 to drive or
receive clock signals provided by the TXC and RXC signal lines. The
factory configures the module for asynchronous communication, that is,
installs no jumpers. Refer to Chapter 2 if your application requires
configuring ports 1 and 2 for synchronous communication.
5. If using a PROM version of the 162Bug, install the PROM device in socket
U47. Be sure that the physical chip orientation is correct, that is, with the
flatted corner of the PROM aligned with the corresponding portion of the
PROM socket on the MVME162 module.
Check the jumper installation on header J21 for correct size. Connect pins 1
and 2 on J21 for 27C080 devices, or pins 2 and 3 for 27C040 devices. The factory
default is 2 and 3.
Remove the jumper on J22 pins 9 and 10.
6. Refer to the set-up procedure for your particular chassis or system for
details concerning the installation of the MVME162.
7. Connect the terminal that is to be used as the 162Bug system console to the
default debug EIA-232-D port at serial port 1 on the front panel of the
MVME162 module. Refer to Chapter 2 for other connection options. 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 MVME162 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 162Bug debugger.
Note
In order for high-baud rate serial communication between
162Bug 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.
8. 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 MVME712X transition module), connect the
