Installing the Hardware

3-21

Connect and install any optional SCSI device 
cables from J3 on the P2 Adapter to internal 
devices and/or the MVME712B or MVME712M to 
external SCSI devices (typical conÞgurations 
shown in 

).

Connect the terminal to be used as the 187Bug system console to the default 
debug EIA-232-D port at serial port 1 on the MVME712X transition module.

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 MVME187 ports at 
powerup)

After power-up, the baud rate of the debug port can be reconÞgured by using 
the Port Format (PF) command of the 187Bug debugger. 

Connect devices such as a host computer system and/or a serial printer to the 
other EIA-232-D port connectors with the appropriate cables and conÞguration.
After power-up, these ports can be reconÞgured by programming the 
MVME187 CD2401 Serial Controller Chip (SCC), or by using the 187Bug PF 
command. 

Set up the device serial ports as described in Step 
3. 
After powerup, the baud rate of the port can be 
reconÞgured by using the Port Format (PF) 
command of the 187Bug debugger.

Connect a parallel device, such as a printer, to the 
printer port on the MVME712X transition module.   
(You may also use a module such as the MVME335 
for a parallel port connection.)
