Barcode Reader technologies general overview for CIS integrated systems
A number of Barcode reading technologies have been employed in the Cubiscan Integrated Systems projects over the years. This article will give descriptions and terminology to assist in determining which type of reader is being used, and provide a guide to more specific information concerning that reader type for deeper troubleshooting.
Most Common Solution: Before we begin, in most cases the solution to a barcode reader issue is to first: check Photo Eye alignment and function, second: power cycle the barcode reader(s) and then reset the Cubiscan Software windows to verify there is a good connection to all barcode readers in the system. This will solve most problems where data is not being received from the barcode reader(s).
SICK Barcode Readers (Signature Blue in Color):
Most early CIS systems employed SICK barcode readers. The SOPAS Engineering Tool Software interface is used to work with all SICK equipment. Model types commonly used were CLV490 CLV690, CLV650, and CLV630 models. These are laser line based barcode reading technologies which have a spinning mirror, and CLV690 and CLV650 models have a focus mechanism in them as well to handle packages at various heights. These parts are mechanical in nature, and will wear out over time. A CLV690 can last 7-12 years on average running 24/7. A CLV650 or CLV630 will typically last 4 to 7 years running 24/7. If the customer will power them off when not in use, the lifespan will be much longer, but still be consistent in overall running hours. At times a central controller (MSC800) was used to act as a central hub for a scanner network. This is common where a SICK based Dimensioner system is also in place. Most stand alone, and barcode reader pairs (Verify Scan pairs) are connected to a CDM box for power, trigger signals, CAN Network connections, Serial Data Output, & backup memory.

Right around 2014 or so Barcode technologies shifted toward camera based barcode readers, and the Lector series from SICK was used in many of the CIS system installations along with the laser based readers for a time. The Lector series readers have a manual focus lens assembly, and various types of light rings that can be used. All other parameters can be adjusted through the SOPAS software interface. Different styles include the Lector 652, and Lector 632 flex models.

Cognex Readers (Signature Yellow):
For a brief period of time, and in limited project applications Cognex barcode readers were used. These are limited to 4Over in Glendale, CA, and a unique Electrolux Dishwasher tub label generator project. There may have been a couple of other limited applications where the customer choose Cognex equipment with other integrator companies as well. The Dataman software is used to interface with the Cognex readers.
Keyence Readers:
Keyence Barcode readers became the standard for CIS installations right around 2019. The Keyence Cameras have an autofocus mechanism built in that allows for more remote support capability. A target box at the correct distance from the camera is needed for focusing, but all else can be done remotely. The AutoID software is used to communicate with the Keyence equipment. Principle reader types used today are SR1000, SR2000, & SR5000 models. All 3 are available in standard and wide view camera types. A "W" is added to the model number for wide view.
