Pick-to-Light & Put-to-Light

Frequently Asked Questions

Our Pick-to-Light system easily integrates with your existing ERP or WMS or even Microsoft Office.  A simple URL request, sent to our server on the Amazon Cloud, causes the associated Pick-to-Light device to light up with the picker’s name, SKU and quantity to pick!

Overview

What is a Pick-to-Light System

Pick-to-Light systems optimize warehouse picking and reduce errors by automating the order picking process. Most pick-to-light systems are costly and difficult to install. Our Pick-to-Light solution brings the Industrial Internet of Things (IIoT) to the warehouse with interactive pick-to-light devices that can display:

  • Picker’s name
  • SKU and quantity of item
  • Custom messages

Our Pick-to-Light system is affordable, mobile, easy to implement, and can be integrated with your current ERP or WMS system.

What is Put-to Light?

Put-to-Light is an additional feature of our Pick-to-Light system which assists pickers or re-stockers in putting inventory into the correct location (including picking carts and put walls).  A simple URL call can light up a device to show where inventory needs to be placed.

Examples:

  • Batch picking with separate bins
  • Put-wall
  • Restocking
  • Returning canceled orders to original inventory locations

PTL devices can display:

  • Name of re-stocker
  • Item and/or SKU
  • Number of items
  • Stocking or handling instructions
  • Some other custom data

What is a Picklist?

Sample pick-list for warehouse order fulfillment

A picklist is a list of lines that need to be picked from inventory to fulfill an order.

Each picklist line contains:

  • Product name or SKU number
  • Quantity

Each picklist line can also contain:

  • Picture
  • Area
  • Location
  • Dimensions
  • Weight

How much does Pick-to-Light cost?

It’s far more economical than you might imagine! Unlike other companies offering Pick-to-Light systems, we’re totally upfront about our pricing.  In fact, you can lease a Starter Kit with ten Pick-to-Light devices to see if it boosts your productivity.

Components

What components make up the Pick-to-Light system?

When integrated with a typical WMS or ERP, our Pick-to-Light system requires two things:

It is easy to integrate the Pick-to-Light system into your own ERP or WMS system and not have to change or adopt a new software. It’s as simple as adding URL calls.

If you don’t have an ERP or WMS, check out our SKU-Keeper solution.

What is a Pick-to-Light Device?

Pick-to-Light Cloud Display Device IoT for the WarehousePick-to-Light devices are modern IoT devices that you can use as signposts in your business. They can keep track of the SKU’s at a location and/or guide pickers to a destination.  Using a simple URL request, devices can be made to light up with, for example, a pickers name, the SKU and quantity to pick. The devices can even play a custom tune for each picker. The devices are wireless, battery powered (very long battery life) and easy to install.

Pick-to-Light devices can be easily integrated with an existing ERP or WMS.

What is a Turbo?

Turbos connect Pick-to-Light devices to the cloud.

PTL devices cannot connect to the cloud by themselves – they need the help of a Turbo or SKU-Station. The Turbo is the simplest way for the devices to connect to the cloud.

In large warehouses or ones that span multiple rooms, you might need additional Turbos. In busy systems, where multiple requests overlap, adding extra Turbos will decrease response times, making the system faster.

What is a SKU-Station?

The SKU-Station is a kiosk for your warehouse or manufacturing floor. SKU-Stations facilitate communication with the pick-to-light devices and allow employees to interact with your ERP or WMS (web-only) or the SKU-Keeper inventory management system.

SKU-Stations can be customized with a touch screen and can be self-standing or rack mounted.  Contact us to find a solution that is right for you.

Details

How long does it take for the Pick-to-Light device to light-up?

A single Pick-to-Light device should respond to a URL request in less than a couple of seconds.

A typical picklist with five items will generate five URL requests and light up five Pick-to-Light devices in approximately ten seconds (the first after two seconds, and the last after about ten seconds).  Adding additional Turbo’s can reduce the time.

If I’m not using SKU-Keeper software, how do I know what is stored in a location?

One important feature of the Pick-to-Light devices is that they can retain information that can be displayed when you push the button. In a similar way to activating a PTL device, a simple URL can be used to set this content.

Integrating this functionality with a typical ERP or WMS is easy. With it, you can simply push the button on the top of the device to cycle through information such as:

  • SKU and quantity
  • Device area and location
  • Device uptime
  • Device battery voltage

Not every location needs a device. If there no PTL device at a particular location, you’ll have to revert to your ERP or WMS to determine what’s stored there.

How long do the batteries last?

The Pick-to-Light devices have been designed to maximize battery efficiency.  PTL devices spend most of the time “sleeping”.

With typical use, the two AA batteries could last years. It really depends on how frequently you activate the device.

Is there a low-battery warning?

Battery voltage of each device is continuously monitored by the system.

The device itself always displays the current battery voltage or a low-battery warning. And on the SKU-Keeper server, you can easily get a list of Pick-to-Light devices and their locations that have battery levels below a cut-off value that you specify.

How do you change the batteries?

Battery changes are quick and easy. Batteries are accessible from the front of the device, without removal. Don’t worry, you’ll never lose Pick-to-Light device data because the devices re-synchronize with the database upon startup.

How Does it Work?

How do the Pick-to-Light devices work?

Our Pick-to-Light system uses the ultimate standard – a simple web URL.

A simple URL is constructed, sent to our servers on the Amazon Web Services (AWS) cloud and then forwarded to the SKU-Keeper app, Turbo, or SKU-Station, which lights up a Pick-to-Light device.

Pick-to-Light IoT URL

What are the components of the URL?

A simple URL request, sent to our server on the Amazon Cloud, causes the associated Pick-to-Light device to light up with the picker’s name, SKU and quantity to pick.

Pick-to-Light IoT URL

  • Amazon cloud
  • Device ID
  • Call (pick, flash or static)
  • Line 1 text
  • Line 2 text
  • Tempo & tune
  • Time (seconds the light stays on)

There are three basic calls to the device:

  • Pick – Turns light on, displays info and plays a tune
  • Flash – Flashes light, displays info and plays a tune
  • Static – Sets background data in device–will be displayed when the button is pushed

How is Pick-to-Light the Internet of Things (IoT)

The Internet of Things (IoT) is a collection of devices that are put on the internet, connected to each other and controlled remotely. Our Pick-to-Light system brings the Industrial Internet of Things (IIOT) to the warehouse with innovative devices that light up with the picker’s name, SKU and quantity to pick!

Is this Industry 4.0?

Industry 4.0 is the latest trend in automation with the creation of factories and warehouses that leverage the Internet of Things (IoT) and cloud computing.

Our Pick-to-Light system brings the Internet of Things and cloud computing to the warehouse with devices that light up with the picker’s name, SKU and quantity to pick!

Installation

What are the requirements?

The easiest way to connect the Pick-to-Light devices to the Internet is to install one or more Turbos.  Turbos are typically hung high on a wall or ceiling and can be connected directly over Ethernet (DHCP) to your LAN.  If you already have WiFi in your warehouse, you can connect to the Turbo to your WiFi network.

If you decide to use SKU-Stations, those too can be connected via Ethernet or WiFi and obviate the need for Turbos.

Pick-to-Light devices work with any ERP or WMS solution, our SKU-Keeper software, or even Microsoft Office.  A simple URL is all it takes to activate a device.

Where can Pick-to-Light devices be mounted?

Pick-to-Light devices can be mounted to picking carts, boxes, bins, containers, shelving, pallet racking, put-walls, and more. You can mount a device just about anywhere!

How do I attach the Pick-to-Light devices to my warehouse locations?

The most popular method is outdoor double-sided tape. But you can also use screws, bolts, zip ties, wire, string, twine or whatever you most feel comfortable using.

Can I put Pick-to-Light devices in shipping and receiving bays?

Absolutely! Mount Pick-to-Light devices wherever you want to keep track of inventory and products coming in and going out. The PTL devices will help you find and keep an accurate count of what’s on hand 24/7.

Integration

Can the pick-to-light devices integrate with my current ERP or WMS?

Pick-to-Light devices can easily be integrated with any ERP or WMS system.  The simplest way is to intercept the barcode scan at the beginning of a picklist and create a URL for each line of the pick list.

If you don’t have an ERP or WMS system, check out our SKU-Keeper inventory management software.

What if I don’t have an inventory management solution?

We offer an affordable and innovative inventory management system designed to optimize the Pick-to-Light devices.  The SKU-Keeper inventory management software can be accessed using a desktop browser, Android device, or SKU-Station (warehouse workstation).

Find inventory in a flash, check on orders, batch pick/restock items or run sophisticated custom reports all from the SKU-Keeper Website.

What else can I do with the pick-to-light devices?

The only limit is your imagination! The devices can light up and display any message you’d like. We challenge you to come up with new ways to use them in your operations.
