7-28 System Instrument Command Reference
DIAGnostic:UPLoad:SADDress? < address> ,< byte_count> Returns the
number of bytes specified by byte_count, at address.
Parameter Parameter
Name Type
address numeric
byte_count numeric
Address may be specified in decimal, hex (# H), octal (# Q), or binary
(# B) formats.
UPLoad is done by word (16 bit) access so address and byte_count must
be even.
The register address in A16 address space can be determined by:
1FC000 + (LADDR * 64) + register_number
16
where 1FC000 is the base address in the VXIbus A16 address space,
16
LADDR is the device logical address, 64 is the number of address bytes
per device, and
retrieved.
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
2000000 and address E00000
16
Data is returned in the Definite Block Response Data format:
# < non-zero digit> < digit(s)> < data byte(s)>
Where the value of < non-zero digit> equals the number of < digit(s)> .
The value of < digit(s)> taken as a decimal integer indicates the number
of < data byte(s)> to expect in the block.

This program reads 1024 data bytes from register 32 on a device with logical
address 40 in Command Module A16 address space.
DIM HEADER$[6],DATA(1024)
6 chars for "# 41024" header
1024 chars for data bytes
OUTPUT "DIAG:UPL:SADD? # H1FCA20,1024"
request 1 Kbyte from device
register 32
enter HEADER$
strip "# 41024" from data
enter DATA
get 1024 data bytes into string; use enter format so statement
won't terminate on CRs or LFs etc. Line Feed (LF) and EOI
follow the last character retrieved.
