Installation and Startup

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.

3

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.

 

 

 

In order for high-baud rate serial communication between

N

 

 

ote

 

 

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

MVME162IG/D2
