User Manual (HB-USP-GT1L-B) Chapter 1. Overview 1.1 Overview of Product HB-USP-GT1L-B is a model that receives input from various sensors of voltage, current and resistive output types and transfers processed data via Bluetooth wireless communication. Data obtained from each sensor are sent to sink node (HB-USP-GT2-B), and they can be sent from the sink node to a monitoring device through Ethernet. Data can be checked from a remote distance by configuring additional network using the internet or Wi-Fi. 1.2 Composition of Product Name Quantity Remark Main body (HB-USP-GT1L-B) Sensor connector Power adapter RF antenna Ferrite core 1 6 1 1 4 Connector to connect main body and sensor Input : AC100~240V(50/60Hz) Output : DC5V 4A Helical antenna (2.4GHz, 2.85 dBi) Attached to sensor cable

User Manual (HB-USP-GT1L-B) 2.2 Hardware Description 2.2.1 Block Diagram The figure below shows block diagram of the product hardware.
<Block Diagram of HB-USP-GT1L-B>
This product is operated by receiving 5V from DC adaptor. Voltage of 5V is supplied to analog circuit, RS-485 circuit, and sensor that requires power via sensor connector. DC5V voltage is passed through regulator and converted to 3.3V, and 3.3V is supplied to microprocessor, digital sensor circuit, internal flash, RTC and Bluetooth module. Sensor signals obtained from sensors are passed through the analog circuit and sent to ADC input of the microprocessor. The microprocessor handles and processes data, and it can send data via Bluetooth module or RS-485 port. When sending data using the Bluetooth module, sink node is used. Communication method can be switched to Ethernet on the sink node. Various settings are saved on flash, which is loaded automatically upon booting. Setting values are saved automatically when network device information is updated.
