A/D Inputs Tab
The “A/D Inputs” tab displays the current state of the analog
-to-digital channels for Sealevel I/O devices that
feature A/D inputs. Settings are provided for both device wide and per-channel configuration
.
The “Device Configuration” selection drop
-box adjusts the arrangement and function of the A/D input channels.
Input channels are displayed as banks (groups of eight). Each channel is range configurable via the voltage
range dropdown list. Both the channel voltage range and device-wide configuration are set on a dropdown list.
There is no need to save your settings
–
they are automatically saved to the device as you select the various
configuration options.
“10x Hardware Gain Enabled” checkbox –
Indicates whether or not the onboard hardware gain jumper is
currently set. This option is
not
user configurable
–
it only reflects the status of the onboard hardware jumper
settings. Set the hardware jumper to enable this functionality, which allows smaller voltages to be measured
more accurately (e.g., a 0-1V input signal can be measured more accurately by enabling the 10x hardware gain
jumper and setting the SeaI/O-470 A/D input channel for 0-10V range).
“Show Hexadecimal Values” checkbox –
Displays the values returned by the A/D converter as a hexadecimal
value without converting the values to engineering units (i.e., Amps or Volts)
