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)
