The **Advantech UPOS-315A-R0B0E** is a high-performance Point-of-Sale (POS) system designed for retail and hospitality environments. It is part of the UPOS-300 series, characterized by its sleek aesthetic and industrial-grade electronic components. --- ### Core Electronic Specifications The internal hardware is built to balance power efficiency with the processing needs of modern transaction software. | Component | Specification Details | | :--- | :--- | | **Processor (CPU)** | Intel® Core™ i3-6100U (Dual Core, 2.3 GHz) | | **Memory (RAM)** | 4GB DDR4 2133MHz (Expandable up to 16GB via 1x SO-DIMM) | | **Storage** | 1 x 2.5" SATA HDD/SSD (Standard configuration often includes 64GB/128GB SSD) | | **Display Panel** | 15" TFT LCD with LED Backlight | | **Resolution** | 1024 x 768 (XGA) | | **Touch Controller** | Projected Capacitive (P-CAP) Multi-touch (USB Interface) | --- ### Connectivity and I/O Interface The electronic versatility of the UPOS-315A lies in its wide range of ports, allowing it to interface with peripherals like receipt printers, barcode scanners, and cash drawers. * **Serial Ports:** 4 x COM ports (DB9; RI/5V/12V BIOS selectable). * **USB Ports:** 3 x USB 2.0, 1 x USB 3.0, and 1 x Powered USB (24V). * **Networking:** 1 x Gigabit Ethernet (RJ45). * **Cash Drawer Port:** 1 x RJ11 (supports 12V/24V). * **Video Output:** 1 x VGA for secondary customer-facing displays. --- ### Key Electronic Features #### 1. Low Power Consumption The use of the "U" series Intel processor ensures that the system generates minimal heat. This allows for a **fanless design**, reducing mechanical failure points and noise, and preventing dust intake into the electronic circuitry. #### 2. Power Management The system is powered by a 60W/84W DC power adapter. It includes specialized circuitry to support **Powered USB (24V)**, which allows the POS terminal to provide power directly to heavy-duty peripherals (like thermal printers) without requiring extra power bricks. #### 3. Reliability and Protection * **IP65 Rating:** The front panel is protected against dust and water ingress. * **Watchdog Timer:** An electronic timer that automatically resets the system if the software hangs, ensuring 24/7 operational uptime. --- ### Modular Expansion Options The internal PCB (Printed Circuit Board) supports various daughtercards for specific retail needs: * **MSR/VFD:** Headers for Magnetic Stripe Readers or Vacuum Fluorescent Displays. * **Wi-Fi:** Mini PCIe slot for wireless connectivity modules.
