It offers the same networking capabilities as wired Ethernet but without the need to run cables, which is ideal for installations where wiring is difficult or where scales need to be mobile. The wireless module interfaces with your facility’s Wi-Fi network (802.11b/g) to send weight data directly to any computer on the network, all via standard TCP/IP networking.
KEY PERFORMANCE FEATURES INCLUDE
Freedom from Cables
Wireless Ethernet frees you from the cost and constraints of running network cables to the scale. Scales can be placed or moved anywhere within the Wi-Fi coverage area (approximately 300–400 feet indoors, depending on the environment) and still communicate with the system.
Seamless Integration
The scale joins your existing Wi-Fi LAN just like any other wireless device. It utilizes TCP/IP, so weight data is accessible to software applications on any networked PC as if the scale were plugged in via cable. This makes real-time data collection and monitoring possible over the air.
Secure Communications
Doran’s wireless option supports standard Wi-Fi security protocols to keep your network and data safe. Encryption and authentication (such as WPA/WPA2 and enterprise security) are employed, ensuring the scale’s data transmission integrates securely into corporate networks without compromising IT policies.
Industrial Design
The WiFi hardware is installed internally and includes a rugged antenna solution. For example, a flexible antenna is mounted via a NEMA 4X-rated bulkhead fitting on the back of the indicator. This protected design maintains the scale’s washdown protection (IP67) while ensuring a strong wireless signal for reliable communication in industrial environments.
Bluetooth.
The Bluetooth communication option is a short-range wireless solution for connecting Doran scales directly to a PC or other host device without needing a network infrastructure. This option consists of an internal Bluetooth module inside the scale indicator (with no external antenna required) and a matching USB Bluetooth adapter for your PC. It creates a simple point-to-point wireless link – you plug the Bluetooth dongle into your computer, and the scale automatically pairs to transmit data. The high-power Class 1 Bluetooth system used by Doran supports communication up to about 300 feet (line of sight) and can link multiple scales to one PC.
KEY PERFORMANCE FEATURES INCLUDE
Plug-and-Play
No complex networking or IT setup is required. With the factory-installed Bluetooth module and the provided PC adapter, there are no cables to run or Wi-Fi networks to join. Simply plug in the adapter and the scale will send data wirelessly – it’s an instant cable replacement for serial/USB.
Fast Data Transfer
The Bluetooth link pushes weight data from the scale to the computer in real time. This event-driven communication can be faster and more efficient than traditional serial methods that require the computer to continuously poll the scale. For example, weight readings can stream immediately into an Excel spreadsheet using Doran’s Excelerator software or other data collection programs, with minimal latency.
Multi-Scale Connectivity
A single Bluetooth adapter on a PC can handle input from up to seven Doran scales equipped with the Bluetooth option. This allows you to wirelessly network several scales to one workstation for centralized data logging. The system is ideal for setups in which multiple nearby scales need to report to one computer (e.g. multiple production stations feeding one QA computer).
Cost-Effective Solution
Bluetooth is an economical wireless alternative compared to a full WiFi network interface. It delivers wireless functionality at a lower cost, making it attractive for smaller installations or temporary applications. You get the benefit of wireless communication (untethered setup, quick installation) without the expense of installing network access points or running long cables.
USB.
The USB communication option enables a direct plug-and-play connection from a Doran scale to a PC via a USB port. As newer PCs often lack RS-232 serial ports, this option provides a modern interface for scale data. When the USB option is installed, the scale can be connected to a computer’s USB port and will be recognized as a virtual COM port device. This means existing software that works with serial data (like terminal programs or Doran’s Excelerator data collection software) can communicate with the scale through USB without modifications. The result is a convenient and driver-supported link that retains compatibility with legacy systems while using today’s standard ports.
KEY PERFORMANCE FEATURES INCLUDE
Easy Connectivity
With USB, there is no need to configure baud rates or communication parameters. Simply connect the scale to the computer using a USB cable; the Windows operating system will automatically detect the device and prompt for a one-time driver installation if necessary. Once installed, the scale’s USB interface appears as a standard serial (COM) port to the PC. This plug-and-play approach makes setup very quick and user-friendly.
Expandability
USB supports connecting multiple devices through hubs. You can monitor and collect data from many scales at once – up to 127 USB devices can theoretically be connected to a single PC with hub expansion. This far exceeds the one-to-one limitation of a traditional serial port. For example, several Doran scales can feed data to one computer by using inexpensive USB hubs, each scale operating on its own virtual COM port.
Rugged & Washdown-Safe
Doran’s USB option is built to endure industrial environments. The indicator is fitted with a sealed USB bulkhead connector on the back (exceeding NEMA 4X/IP67 standards), with a screw-on cap to seal it when not in use. Optional heavy-duty USB cables are available (in 6 ft and 16 ft lengths) that include molded sealing caps, creating a watertight connection between the scale and the PC. This design allows you to use USB connectivity in washdown or dusty areas without worrying about water ingress or corrosion.
Flexible Usage
The USB standard cable length limit is about 16 feet (5 meters) for a single cable, which is sufficient for many bench-scale to PC setups. If longer distances are required, the use of active USB hubs or repeaters can extend the range up to approximately 80–96 feet total (by daisy-chaining hubs). This gives you flexibility in plant layout – you can still employ a USB connection even if the scale is across a large room, by using hub extensions. The USB option effectively bridges the gap between the scale and modern computers, ensuring seamless data collection in any setting.
RS-232.
RS-232 serial communication is the classic, time-tested standard for transmitting weight data from a scale to external devices. In the scale industry, RS-232 has been used since the introduction of personal computers, and it remains one of the most common interfaces. Every Doran scale comes equipped with at least one RS-232 port as a standard feature, providing a simple and reliable means to connect to printers, PCs, remote displays, or other equipment. This proven interface ensures that out-of-the-box, a Doran scale can immediately begin sending weight readings to whatever device you need.
KEY PERFORMANCE FEATURES INCLUDE
Industry Standard Interface
Virtually all peripheral devices in weighing systems support RS-232. You can send data to ticket or label printers, connect to a scoreboard or remote display, interface with PLCs or control systems, or feed data into a computer application. This widespread compatibility makes RS-232 a go-to communication method for basic data logging and device control.
Proven Reliability
Over decades of use, RS-232 has proven to be an economical and dependable point-to-point link. It’s a straightforward wired connection (typically via a multi-pin serial connector) that is less complex than network-based communications. In many scenarios, a simple serial cable running from a scale to a nearby device gets the job done with minimal hassle or cost.
Immediate Availability
Because Doran includes RS-232 on all its indicators by default, no additional options or upgrades are needed to utilize it. A standard cable (often provided with the scale) can be connected to start transmitting data. Cable runs can be up to roughly 50 feet (15 m) in length for RS-232 without repeaters, giving flexibility for equipment placement on the factory floor. For longer distances or multi-drop scenarios, other interfaces (like RS-485 or network options) are recommended, but for most small-scale setups, RS-232 offers plenty of reach and simplicity.
Fiber Optic (8100IS and 8200IS only).
Fiber optic communication is utilized on Doran’s intrinsically safe indicators (models 8100IS and 8200IS) to ensure safe data transmission in hazardous environments. Rather than electrical signals, this method uses light sent through fiber optic cable to carry information, meaning there is no electrical current traveling between the scale and the outside devices. In explosive or flammable atmospheres, this is a critical safety feature – fiber optic lines cannot spark or cause ignition. With the fiber optic option, the scale can transmit weight data out of a Class I/II/III Div 1 hazardous area to a safe area without the need for heavy conduit or isolation barriers typically required for copper cables.
KEY PERFORMANCE FEATURES INCLUDE
Intrinsically Safe Connectivity
The 8100IS and 8200IS indicators come standard with dual fiber optic ports for data communication. These ports provide a full duplex (bi-directional) serial link over light, effectively replacing an RS-232 connection with an optical link. Because no electrical energy passes through the fiber, it meets the stringent requirements for intrinsic safety in hazardous (explosion-risk) zones. Operators can gather data from or send commands to the scale without any risk of igniting vapors or dust.
Long Distance, High Integrity Signal
Fiber optic communication not only enhances safety but also performance. It can reliably carry the signal over long distances (up to 1000 feet) without repeaters, far exceeding typical copper serial cable limits. The optical signal is immune to electromagnetic interference and radio-frequency noise, which is ideal in facilities with heavy machinery or RF equipment. This ensures that even in environments with high electrical noise, the weight data travels intact and error-free to the receiving system.
Simplified Hazardous-Area Installation
In an intrinsic safety scenario, running standard cables usually means encasing them in conduit and using explosion-proof fittings – a costly and time-consuming installation. Fiber optics simplifies this: the lightweight fiber cable can be run through the area without special conduit, significantly reducing installation and maintenance efforts. The absence of metal wiring removes the need for complex grounding or shielding practices as well.
Safe Area Interface
To use the fiber link with standard equipment, Doran provides a fiber optic interface converter located in the safe area. This converter takes the light signal from the fiber and converts it back to a conventional RS-232 serial output (or other needed interface) that can plug into computers, printers, or PLCs outside the hazardous zone. In practice, the intrinsically safe scale in the hazardous area connects via fiber to the converter in the non-hazardous area, and from there to your data collection software or devices. This allows seamless integration of hazardous-area scales into your normal operations and data streams, with full safety compliance.
