The [ROUTe:]FUNCtion? query returns the current configuration of the
module in the specified slot. The returned string will be one of WIRE1,
WIRE2, BIWIRE2, or WIRE4. An error is generated if no module is
installed.
[ROUTe:]
DIAGnostic
:SPEEK? <slot>,4
:SPOKE <slot>,0,<data>
These commands read and write an 8-bit data register on the 44475A
Breadboard Module (see page 251).
Using these commands with newer modules (models beginning with
N22xxx) will generate an error.
Valid slot numbers are:
DIAG:SPEEK? returns a decimal number representing the binary
weighted values of the bits in the register connected to the DI lines of the
breadboard. 4 is the register number. Any other register number will not
generate an error and will return the value 255.
DIAG:SPOKE writes a decimal number (<data>) representing the binary
weighted values of the bits to the register connected to the DO lines of
the breadboard. 0 is the register number. Any other register number will
not generate an error but will have no effect.
In the form of the value returned or written as data, a “1” represents a
TTL high and a “0” represents a TTL low on the DI or DO line.
3499A slots 1 through 5
3499B slots 1 through 2
3499C slots 1 through 9
