Sysfail

The VMEbus Sysfail signal is (according to standards) to be asserted during

Jumper

Power-on Self-test to indicate Self-test is occurring. Some systems instead

interpret the signal as a failure. For this reason, the RF3880 adapter jumpers

the signal on the board.

IN - Sysfail signal asserted on bus during Self-test.

OUT - Sysfail signal not asserted on bus.

Table 5 on page 3 - 7 illustrates the location of the Sysfail Jumper. As shown,

the default for this jumper is IN.

VMEbus

This set of jumpers is used to select the address at which the RF3880 adapter

Address

can be addressed by the system. The jumpers set the upper 7 bits of the 16-bit

address, thereby reserving 512 bytes of address space.

Jumpers

Also available to be set is bit 2 of the address modifier lines. With this jumper

in you can elect to have the RF3880 adapter reserved for short non-privileged

access only. If the jumper is out, the board will be in short supervisory access

mode.

Figure 9 VMEbus Address Jumper

The VMEbus Address jumpers are illustrated in Fig. 3-4. The default address setting of EE00H, with address modifier of 2DH is shown.
