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

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

Interface 1(Pin 1) voltage.

5V/9V/12V Output 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”.

Analog Input Signal Type
Osh/Osl
Unit Fetch

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 4-20mA or 0-10V are optional. This only works when DIP switches has changed. 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. The data unit of this sensor, it just displays on ToolBox for reference.
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.

4.6 Data Retransmission
UC50x series supports data retransmission to ensure the network server can get all data even if the network is down for some times. There are two ways to get the lost data: Network server sends downlink commands to enquire the historical data for specified time
range, see UC50x Series Communication Protocol; When network is down if no response from LinkCheckReq MAC packets for a period of time,
the device will record the network disconnected time and re-transmit the lost data after the device re-connects the network. Here are the steps for data retransmission: 1. Enable data storage feature and data retransmission feature;
32

2. Enable rejoin mode feature and set the number of packets sent. Take below as an example, the device will send LinkCheckReq MAC packets to the network server regularly to check if the network is disconnected; if there is no response for 8+1 times, the join status will change to de-active and the device will record a data lost time point(the time to join the network).
3. After the network connected back, the device will send the missing data, starting from the point in time when the data was lost, according to the reporting interval. Note: 1) If the device is rebooted or powered off during data retransmission and the process is not completed, the device will resend all retransmitted data again after reconnecting to the network; 2) If the network is disconnected again during data retransmission, it will only send the latest disconnection data; 3) The retransmission data format is started with “20”, please refer to UC50x Series Communication Protocol. 4) Data retransmission will increase the uplinks and shorten the battery life.
