Note that the term "End Slave" refers to an ICS-130 board, not the FPDP receiving
board. These classifications are applicable to both Local Bus and FPDP operation. It is
possible therefore, for a board to be a Local Bus Mid-Slave but an FPDP Master, FPDP
End-Slave or FPDP Stand-alone Master. The Master board must be located at one end
of the cable. The End-Slave is located at the opposite end of the cable to the Master.
The Mid-Slaves are located in between the Master and End-Slave boards. In a two
board system, only Master and End-Slave configurations apply. Finally, the Stand-
Alone Master refers to a one board system. The required register settings are
determined by which of these four cases applies to the board in question. Also, switch
and register settings are affected by whether a configuration uses internal or external
clock (EXT_CLK+/-) and trigger (EXT_ACQ+/-) signals.
If the ICS-130 board/s is/are connected to one or more Digital Signal Processor (DSP)
or Array Processor boards using the FPDP, the DSP board/s should be installed in the
chassis at the End-Slave end of the FPDP cable (i.e. the ordering should be Master,
Mid-slaves, End-Slave, DSP). If FPDP is not being used, the position of the DSP
board/s in the chassis with respect to the ICS-130 boards is not important, however it is
recommended that the ICS-130 boards are installed in adjacent slots.

4.2 Jumper and Switch Settings

A number of hardware configuration jumpers (wire links) and one switch block need to be
configured on the ICS-130. Figure 3 shows the locations of the jumpers and switches on
the component side of the board. Switches and jumpers are numbered thus: SWx-y and
JPx-y, referring to position y of switch or jumper x, respectively.

4.2.1 VMEbus Base Address Selection

The VMEbus A24 and A32 Base Address is set with jumpers JP1 (8 positions) and JP3 (2
positions). JP2 is an unused jumper block available for storage of spare jumpers. The
values of these switches are loaded to SCV64 register VMEBAR at power up. This register
may be subsequently reprogrammed by the user (see section 5.2). The ICS-130 address
map occupies a 384KB (Hexadecimal 0x60000) space. In A24 mode, the user may specify
the values of A23 to A19, allowing the base address to be set to any value between
0x00080000 and 0x00F80000, in increments of 0x80000.
The default A24 base address is 0x500000. This is the setting shown in Fig. 3.
