1. Overview
The terminal (PSM-NGT-G01) uses a 2.4GHz low-power wireless communication (IEEE 802.15.4 / BLE) module, WIFI
module, and Ethernet chip in an ARM Coretex-A8 32bit processor environment, and wirelessly communicates with the
counter ( products that measure production-related data).
The terminal is installed in the same production facility as the counter, and the received data is transmitted to the
management server using Ethernet or WIFI communication at regular intervals.
When the counter requests data, the terminal transmits the data to the counter, and BLE communication is possible
through a dedicated smartphone APP.

■ AP module (AM335X)
- It controls LAN chip, WIFI, BLE (MDBT50Q), BLE (RN4870) module and transmits and receives data.
- It performs the designated function and displays the operation status on the LED.
■ WIFI module (WL1835MOD)
- It is controlled by the AP module and transmits the data transmitted from the AP module to the server through
WIFI.
- The data received through WIFI is transmitted to the AP module.
- It uses 2.4G single mode and external antenna.
■ BLE module (MDBT50Q)
- The data transmitted from the AP module is transmitted to the counter through BLE communication.
- The data received through BLE communication is transmitted to the AP module.
■ BLE (RN4870)
- The command requested by the smartphone app through BLE communication is transmitted to the AP module.
- The result processed by the AP module is transmitted to the smartphone app through BLE communication.
The internal block diagram of the terminal is as follows:
