DESCRIPTION

The Hytec NADC 2530 is an 8 channel peak sensing ADC. It features two separate address spaces. On board jumpers specify the base of the control register set and is configured using the -csr configuration option. One of the control registers programs the location of the on board event buffer memory and that is programmed via the -memory configuration option.

This module is no longer being produced and is not recommended for new setups. It should be replaced in existing setups as soon as possible.

OPTIONS

-csr vme-addresss

Sets the module control register base address. Note that this value must match the value selected by the module's jumpers. Note that the VME register space is in A24 space so the valid values are between 0 and 0x00ffffff.

-memory vme-address

Selects the base address that will be programmed for the event memory for the module. The event memory lives in a32 space so legal values are between 0 and 0xffffffff. Note that as this is software programmable, care must be taken to ensure that the event memory does not overlap the address space of any other module. Only the top 11 bits of the vme address are relevant. e.g. 0xffffffff is treated as 0xffe00000.

-ipl interrupt-level

If the module will be used to trigger an interrupt triggered list, this is the interrupt priotiry (the IRQ line the module uses) for thos interrupts. The default value of 0 disables module interrupts. Legal values are 0-7.

-vector status-id

Specifies the status-id the module puts on the bus when an interrupt request is acknowledged.

-lld mv

The floating point low level discriminator value in floating point millivolts between 0 and 819.2. Default is 0.0

-hld volts

High level discrimiator value in floatig point volts from 0 to 8.192 Default is 8.192

-events events-per-interrupt

If the module is run in interrupt mode, this is the number of events it will buffer before interrupting. This defaults to 1 and, in any event, we normally don't use it in interrupt mode. Maximum value is 10.

-zerosuppress on | off

When on, the default, the module supresses channels with values below the lld an above the hld.

-id id

This is a 16 bit value that is placed in the event to identify the module the data came from. Defaults to zero.
