---------------------------------------------------------------------

1. Product Overview
The ISC‑8110U is an industrial‑grade USB‑to‑serial media converter designed and manufactured by ORing. It belongs to the ISC‑x110U industrial series, which includes both the ISC‑4110U (4‑port) and the ISC‑8110U (8‑port) variants. The specific article and product identifier for this model is ISC‑8110U. The device serves as an Industrial Converter providing 1 USB 2.0 upstream port to 8 independent RS‑232 serial ports. It is engineered for rugged environments requiring high‑reliability serial connectivity, integration with legacy RS‑232 equipment, and operation in extended industrial temperature ranges. The converter is housed in a compact metal enclosure and supports DIN‑rail or wall‑mount installation, making it suitable for industrial control, automation, transportation, and infrastructure applications.

2. Key Features
The ISC‑8110U delivers eight RS‑232 ports through a single USB 2.0 interface, enabling high‑density serial connectivity for PCs, industrial controllers, and embedded systems. Key capabilities include full RS‑232 signaling support (TxD, RxD, RTS, CTS, DTR, DSR, DCD, GND), full‑duplex communication, and compatibility with legacy serial equipment. The converter integrates internal high‑speed transient suppressors on all serial data lines, providing 15 kV ESD protection. Dual power options allow the device to draw power directly from the USB bus or from redundant 12–48 VDC external inputs. Extended industrial temperature operation from –40°C to +70°C ensures stable functionality in harsh climates and demanding environments. Eight independent data transmission LEDs provide visual activity feedback for each serial channel, and a dedicated power status LED confirms operational state. Combined with its rugged IP‑30 metal enclosure, minimal footprint, and versatile mounting options, the ISC‑8110U is a high‑performance solution for industrial serial connectivity.

3. Technical Specifications
The physical dimensions of the converter are 26.1 mm (W) × 94.9 mm (D) × 144.3 mm (H), corresponding to approximately 1.03 × 3.74 × 5.68 inches. The unit weighs about 350 grams. The enclosure is constructed with an industrial metal housing compliant with IP‑30 protection class. The ISC‑8110U integrates one USB 2.0 port for upstream host connectivity and eight RS‑232 serial interfaces, accessible via a DB62 male connector on the device. A DB62‑to‑8×DB9 male breakout cable is included, with a length of approximately one meter. Serial ports support baud rates from 300 bps to 921.6 Kbps. Supported RS‑232 signals include TxD, RxD, RTS, CTS, DTR, DSR, DCD, and GND. The device incorporates 15 kV ESD protection on all serial channels. Internal power consumption is approximately 2 watts (400 mA at 5 V when powered through USB). Environmental specifications include storage temperatures from –40°C to +85°C, operating temperatures from –40°C to +70°C, and humidity tolerance of 5% to 95% non‑condensing.

4. Functionality
The ISC‑8110U functions as a USB‑to‑serial media converter that expands a single USB interface into eight independent RS‑232 serial ports. It connects to a host PC or USB hub and enumerates the eight serial interfaces through a driver‑based virtual COM port system. Each RS‑232 channel supports full‑duplex data transmission with standard RS‑232 handshaking lines, enabling connectivity to industrial automation devices, programmable logic controllers, serial sensors, instrumentation, modems, legacy terminals, SCADA equipment, point‑of‑sale devices, and serial‑based data acquisition systems. The device supports multiple operating systems including Windows 2000, Windows 2003, Windows XP, Windows Vista, Windows 7 (both 32‑/64‑bit), Windows Mobile 5/6, PocketPC 2003, Windows CE 4.2–6.0, and Linux x86 32‑/64‑bit. The converter is fully compatible with applications requiring stable, multi‑port serial communication in industrial systems, embedded environments, and legacy‑equipment modernization projects.

5. Components & Accessories
The ISC‑8110U includes several essential components within the standard packaging: the ISC‑8110U converter unit, a one‑meter DB62‑to‑8×DB9 male cable, a USB cable, the ORing Tool CD, a Quick Installation Guide, a DIN‑rail mounting kit, a wall‑mount kit, and a 12 V / 1 A power adapter (with US or EU plug depending on model variant). Optional accessories include ORing DIN‑rail power supplies: DR‑45 series (45 W), DR‑75 series (75 W), and DR‑120 series (120 W). Optional fiber or alternative converter types are available through the ISC‑A B C D E ordering code system, although the ISC‑8110U specifically represents a configuration with one USB port and eight RS‑232 ports. The breakout cable provides DB9 male connectors with standard RS‑232 pin assignments. Pin definitions include: Pin 1 DCD, Pin 2 RXD, Pin 3 TXD, Pin 4 DTR, Pin 5 GND, Pin 6 DSR, Pin 7 RTS, Pin 8 CTS, Pin 9 N.C. The cable is designed to maintain signal integrity and withstand industrial use environments. All included components are engineered for durability and compatibility with the ISC‑8110U system.

6. Installation & Setup
Installation of the ISC‑8110U involves mounting the unit using the provided DIN‑rail or wall‑mount brackets. The device may be powered either directly through the USB bus or via external 12–48 VDC inputs using the 2‑pin terminal block or power jack. Once mounted and powered, users connect the DB62‑to‑DB9 breakout cable to access the eight RS‑232 ports. Driver installation is required for Windows and Linux systems, typically from the included ORing Tool CD. After drivers are installed, the ISC‑8110U enumerates eight virtual COM ports, each corresponding to one RS‑232 interface. The device requires no complex configuration; it operates as a transparent USB‑to‑serial converter. Data LEDs provide real‑time indication of activity on each channel, simplifying troubleshooting and operational validation. Installation is suitable for control cabinets, panels, industrial racks, and wall‑mount scenarios. The compact form factor allows integration into dense industrial environments and legacy equipment retrofits.

7. Performance & Capabilities
Performance characteristics include baud rates from 300 bps up to 921.6 Kbps, supporting both low‑speed control signaling and high‑throughput serial data streams. RS‑232 full‑duplex communication ensures simultaneous transmit and receive operations. High‑speed USB 2.0 host connectivity provides stable bandwidth for all eight serial ports operating concurrently. The built‑in transient suppression and 15 kV ESD protection enhance system stability in noisy electrical environments. Typical power consumption is approximately 2 W, optimizing thermal and energy efficiency. Operational reliability is maintained across a wide temperature range from –40°C to +70°C, enabling deployment in outdoor control systems, transportation infrastructure, power substations, and factory automation. The IP‑30 enclosure and vibration, shock, and free‑fall compliance support deployment in rugged industrial conditions. Limitations include RS‑232‑only serial support (no RS‑485/RS‑422 modes for this specific model), and the device requires a functioning USB host for operation.

8. Standards & Compliance
The ISC‑8110U complies with multiple industrial, safety, and EMC standards. EMI compliance covers FCC Part 15 and CISPR EN55022 Class A for electromagnetic emissions. EMS immunity compliance includes EN61000‑4‑2 (ESD), EN61000‑4‑3 (radiated susceptibility), EN61000‑4‑4 (EFT), EN61000‑4‑5 (surge), EN61000‑4‑6 (conducted susceptibility), EN61000‑4‑8, and EN61000‑4‑11. Mechanical and environmental robustness is certified under IEC60068‑2‑27 (shock), IEC60068‑2‑32 (free fall), and IEC60068‑2‑6 (vibration). Safety certification complies with EN60950‑1. These standards ensure high levels of reliability, safety, and electromagnetic immunity, making the ISC‑8110U suitable for industrial, transportation, commercial, and infrastructure applications requiring regulatory assurance.
