As more and more environments become wired for the Internet, we’ve developed scales to match. You can now monitor and control your Arlyn Scales over your local network. Simply plug the scale into the network and connect to it using our Remote Indicator software. Weights can be recorded, sorted, grouped and analyzed from your workstation PC. It is also possible to set up your network so that you can access the scale from anywhere in the world over the Internet. We also offer a Wireless Ethernet option.

Set Point

The Setpoint output provides some simple Batching and PLC type functions. You may set up to 8 target weights at a time, and use these targets to turn other equipment on and off. Feeders, mixers, motors, valves, solenoids and other devices may be controlled using solid-state relays that are operated by the setpoint outputs. The most common use is automated filling and mixing operations. Through the use of the setup menu, formulas can be input to control how those output lines behave based on the weight applied to the scale platform. Many different formulas may be saved in the scale memory, and recalled when needed.


USB (Universal Serial Bus) is the most common interface on today’s PCs. This option, in combination with Arlyn’s free USB Remote Software allows scale data to be sent to an Excel spreadsheet or Access database file on the PC. The PC can also control the scale’s operation. A utility is also available to send weight data from the scale directly into any Windows application software.


RS-232 is a standard communications protocol used mainly to transmit data from one piece of computerized equipment to another. In the digital scale world, RS232 is used to communicate with printers, programmable logic controllers and computers. Arlyn’s RS232 Option is a bi-directional interface that allows the Scale Indicator to not only send data, but also receive commands from computers and the like. This allows full remote capability. Consult our Options Manual for full details.
Included in the scale’s operating software is a print frame definition editor that allows for customized outputs like complex printed labels.


Need a robust, long distance network protocol to connect several scales and a personal computer? RS-485 is another communication system built into Arlyn Scales. It differs from RS-232 and USB by the distance over which it can successfully transmit and receive – 4000 feet. RS-485 is a “multi-drop” protocol, meaning that several scales can share a single line, forming a network. We also sell an RS-485 to USB interface allowing you to log data and directly control up to ten scales from a single PC.

Time and Date

This is an add-on option to RS232 that gives it the capability to add time (12 or 24hr format), day of week and date to any print frame. The clock is set through the indicators menu system. An internal lithium battery will keep time for up to ten years, even if the power is removed from the scale.

Analog Output

Analog Output is used to communicate with programmable logic controllers and chart recorders. Through the setup menu, full configuration is provided allowing you to set the start and ending currents or voltages. Analog Output is available in two configurations, Current and Voltage output.
Voltage Output = 0 to 5VDC scalable
Current Output = 4 to 20ma scalable

Battery Pack

An internal six cell, rechargeable NiMH battery Pack and its associated peak detect charging circuit can be installed in the scale indicator for portable use. The scale can operate for over twenty hours on a single four hour peak charge.


Many of our customers need to record weights from our scales. Our datalogging option enables your scale to record a weight along with time, data, group and item information. Data is saved on USB drive that can be removed from the scale and read on a personal computer using Microsoft Excel.
