Digital Output Operations
The multifunction module (34907A) has two non-isolated 8-bit input/
output ports which you can use for outputting digital patterns.
• The digital output channels are numbered “ s 01” (lower byte) and
“ s 02” (upper byte), where s represents the slot number.
• You cannot configure a port for output operations if that port is
already configured to be part of the scan list (digital input).
• From the front panel, you can write to one 8-bit output port at a time.
From the remote interface, you can write to both ports
simultaneously.
• From the front-panel only, you can specify whether you want to use
binary or decimal format. Once you have selected the number base, it
is used for all input or output operations on the same port.
• A Factory Reset (
*RST
command), Instrument Preset
(
SYSTem:PRESet
command), and Card Reset (
SYSTem:CPON
command) from the remote interface will reconfigure both ports as
input ports.
Note: A from the front panel resets only the port currently
selected (both ports are not reset).
• Front-Panel Operation : After selecting the output port, press to
edit the bit pattern or decimal value (the least significant bit is on the
right). Press
again to output the bit pattern. To cancel an output
operation in progress, wait for the display to time out.
From the front-panel only, you can specify whether you want to use
binary or decimal format.
