2.2 Configuration
When you first receive the USPIIi-1v, confirm that the installation of jumpers is appropriate to your
application
.
Refer to Appendix § B Jumper and Solder Bead Configurations for a complete listing of jumper
definitions. The default jumper configuration is as follows:
• Baseboard:
– JP1401 set to 1-2 to set the System FLASH to Read-Only
– JP1601 set to 2-3. This jumper setting should not be changed
– JP3801 set to 1-2 to enable assertion of VME SYSRESET (USPIIi-1v must be system controller)
– JP3901 set to 1-2 to enable reception of VME SYSRESET
– JP3304: factory set to mirror PS/2 or Sun configuration. See § 2.1 Determine Board Type and
Configuration
– All other baseboard jumpers are left uninstalled
• I/O Board:
– JP0705, JP0706 installed to configure Serial Port C and D as RS232.
– JP0801, JP0802, JP0803, JP0804, JP0805, JP0806, JP0808 set to 2-3 to configure Serial Port C
and D as RS232.
– All other I/O board jumpers are left uninstalled
• PMC Carrier Board:
– J11 and J12, the User I/O Adapter Card, is left uninstalled. This will route all 64 bits of User I/O
on the PMC Carrier board to PMC #1, as opposed to routing 32 bits of User I/O to PMC #1 and
32 bits of User I/O to PMC #2.
If the default jumper settings meet your requirements you are now ready to install the USPIIi-1v in a standard
VME chassis.
In addition to the USPIIi-1v a standard VME chassis with P1/P2 backplane is required. If the USPIIi-1v is to
be used in a workstation configuration instead of as an embedded controller, a hard disk and graphics frame
buffer or serial terminal will also be required.
2.3 Backplane Jumper Settings
In the case of the USPIIi-1v/2c and USPIIi-1v/3, certain signals require jumpers on the backplane of the VME
chassis. If the VME chassis does not have auto-jumpering capability, these jumpers need to be manually set.
The pins that require jumpers are located on the
second slot occupied by the USPIIi-1v board:
• Pin A20 should be jumpered to pin A21 (IACK)
• Pin B4 should be jumpered to pin B5 (BG0)
