4.3.2 Analog Input
1. Connect analog device to analog input ports on interface 1. If the analog device requires
power from the UC50x, connect the power cable of analog device to the power output on
interface 1.
2. Enable analog input and configure analog settings according to the requirements of the
analog sensor .
Parameters
Description
Interface 1(Pin 1)
5V/9V/12V Output
Enable 5V/9V/12V power output of interface 1 to supply power to analog
devices. It’s 12V by default and you can change DIP switches to change
voltage.

18
Power Output Time Before Collect: power supply time before collecting data
for terminal device initialization. Range: 0-600s.
Power Supply Current: supply current as sensor required. Range: 0-60mA
Interface 1(Pin 2)
3.3V Output
Enable 3.3V power output of interface 1 to supply power to analog devices.
Power Supply Mode: Select “Continuous power supply” or “Configurable
power supply time”.
Power Output Time Before Collect: power supply time before collecting data
for terminal device initialization. Range: 0-600s.
Power Supply Current: supply current as sensor required. Range: 0-60mA
Analog Input
Signal Type
4-20mA or 0-10V are optional. This only works when DIP switches has
changed.
Osh/Osl
Osh is the high limit of the scale and osl is the low limit of the scale for the
scaled output value. After setting, the device will upload the scaled values.
Unit
The data unit of this sensor, it just displays on ToolBox for reference.
Fetch
Click to fetch current value of sensor.
Note: analog input scaling formula
Ov = [(Osh - Osl) * (Iv - Isl) / (Ish - Isl)] + Osl
This can also be rewritten as:
Ov = [(Osh - Osl)/(lsh - lsl)/(lsh - lsl)] + Osl
The variables are pertinent to the scaling formula:
Ov = scaled output value
Iv = analog input value
Osh = high limit of the scale for the scaled output value
Osl = low limit of the scale for the scaled output value
Ish = high limit of the scale for the analog input value
Isl = low limit of the scale for the analog input value
For example, a analog wind sensor can us 4-20mA to point to 0-32 m/s, the corresponding
variables are: Osh=32 m/s, osl=0 m/s, lsh=20mA, lsl=4mA.
When it measures 6mA, the real wind speed is Ov= [(32 - 0) * (6 - 4) / (20 - 4)] + 0=4 m/s.
3. For ToolBox software, click Fetch to check if UC50x can read correct data from analog
devices.
Note: When you use power output to power analog devices, it only supplies power when
reporting interval is coming. It’s suggested to power slave devices with external power during
the PoC test.

19
For ToolBox App,
a. Click Collect and attach smart phone to the device to collect data.
b. Click Fetch and attach smart phone to the device to read the data.
