Doran Digital Scales with Grading Food Processing are available at Central Carolina Scale Electronic Scales CatalogDigital Scale Operation -- USB 2.0 Communication Over 30 years ago, Doran introduced the industry's first Stainless Steel Checkweigher. Today, Doran is blazing new territory with the new, exciting and powerful features of the Excel board found in the 7400, 7000XL, 8000XL, and 4300. Once again, Doran is "changing the way we weigh" with the new USB communications which is paving a way for many customers to accelerate their weighing applications. Doran's USB scale communication feature is growing in popularity among scale end users. Doran USB Option for Excel Series Indicators OVERVIEW
In the scale
industry, the RS232 Serial Port has been used for communications
between scales, computers or printers since the introduction of
the personal computer. In 2002, PC manufacturers have agreed to
obsolete Serial Ports over time and replace them with USB communication
ports. Therefore, todays computers are not always equipped
with an RS-232 port, which makes the use of USB absolutely necessary. With the migration to USB comes several benefits of using USB communications over RS232 Serial Ports. These include ease of use, reliability, flexibility, and compatibility. When a USB device is connected:
Doran has responded
to this industry trend by introducing the USB option for our Excel
Series Indicators. USB allows a PC to monitor several scales at
once, utilizing included USB ports on the As with all Excel Series communications options, the USB option exceeds the NEMA 4X and IP67 washdown standards. A bulkhead connector at the rear of the scale, along with Dorans optional USB cables, provides a rugged and reliable USB cable connection. A mating cap is molded to the USB cable and screws into place, which seals and solidly holds the USB connection. A protective cap is included at the rear of the indicator to provide washdown protection when the mating USB cable is disconnected. Doran offers a 6 foot and a 16 foot cable that includes these washdown features. The USB standard limits cable length to 16 feet, although a maximum distance of 96 feet can be achieved with the use of five USB hubs connected in series. APPLICATIONS To allow for five scales to be connected via USB to a PC at one time, a five-port USB hub was purchased. This hub connected to each of the five Doran 7000XL Indicators via a USB cable. In order to sort the data in the Excel spreadsheets at a later time, a custom data string was created using the Doran Dimension Indicator setup software. Each scale had a data string that included a scale ID and the current weight and units. Once configured, Dorans Excelerator Data Collection Software, sent data from the scales directly into the Excel spreadsheet, with each scale sending data to a different sheet in the workbook. Since Excelerator automatically sent data into Microsoft Excel, the data can be immediately analyzed to determine the precision of the QC sample from the manufacturing line. The customer now controls his line process with a ten piece sample from his line three times daily and makes equipment control adjustments when necessary.
