Parameters

DIAGnostic:CHECked:DOWNload:SADDress < address> ,< data> writes data
to non-volatile User RAM at a single address specified by address using error
correction. It can also write to devices with registers in the A16 address space.
Parameter Parameter
Name Type
address numeric
data arbitrary block
program data
This command is typically used to send data to a device which accepts
data at a single address. It is the only way to send binary data to single
addresses over a serial (RS232C) line.
Most computers terminate an OUTPUT, PRINT, or WRITE statement
with a carriage return or carriage return and line feed. These
End-Of-Line characters must be either accounted for (NRAM segment
sized to accommodate them), or suppressed using an appropriate
IMAGE or FORMAT statement. Some helpful methods:
– Control the End-Of-Line characters with format statements.
– Use the Definite Length Arbitrary Block Program Data format (see
example) to send your data rather than the Indefinite Length
Arbitrary Block Program Data format.
A register address in A16 address space can be determined by:
1FC00 + (LADDR * 64) + register_number
16
where 1FC000 is the base address in the System Instrument A16 space,
16
LADDR is the device logical address, 64 is the number of address bytes
per device, and register_number is the register to which the data is
written.
If the device is an A24 device, the address can be determined using the
VXI:CONF:DLISt command to find the base address in A24, and then
adding the register_number to that value. A24 memory between address
200000 and address E00000
16
Address may be specified in decimal, hex (# H), octal (# Q), or binary
(# B) formats. DOWNload is done by word (16 bit) access so address
must be even.
