Comments
•
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. Listed below are some
helpful methods:
–
Control the End-Of-Line characters with format statements.
–
Use the Definite Length Arbitrary Block Program Data format
(see example on page 121) 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:
1FC000
16
+ (LADDR * 64) + register_number
Where 1FC000
16
is the base address in the command module A16
space, 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:CONFigure:DLISt? command to find the base address in A24, and
then adding the register_number to that value. A24 memory between
address 200000
16
and address E00000
16
is directly addressable by the
command module.
•
<
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.
