A/D Inputs Tab
The “A/D Inputs” tab displays the current state of the analog-to-digital channels for
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 12-Bit Hex 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)
