Ident System EVS138 Imager is a barcode scanner designed for mobile forklift mounting used for pallet handling. To enable use with double pallets EVS138 was designed with the possibility of connecting several cameras in parallel in order to scan a wider area.

EVS138 imager will read all common barcodes and 2D codes. It is based on the latest matrix technology and can withstand the tough industrial environments of forklift truck applications, including the shock and vibration stresses. It can also be supplied with its own heating element for use in freeze storages or outdoors in cold environments down to minus 30 degrees Celcius.

EVS138 can also be integrated with RFID readers such as our Ideal125, for positional readings of floor-embedded tags. The EVS138 imager autofocus and built-in error correction capabilities allow it to read codes of varied quality at distances between 0,2 m up to 13 m.

For LF 125 and 134,5 kHz systems, IdentSystem we can custom make antennas for specific needs, to get that perfect fit that you need when working in difficult environments.

We can design antennas to work with both our own IDeal125  and IDeal134 (TambourID) systems as well as Baumer OIS-L readers, trimming them in advance for placement by metal or air.

Apart from the normal antennas, we can also offer threaded antennas to screw in holes like bolts, or small, boxed antennas. Other options are also available – we help you find the best solution for your needs.Contact us for more information.

Something we have not talked about much here in our series of newsletters is the option to combine our EVS144 code readers with for example the Ideal 125 for fully automated and controlled pick-and-place operations in your warehouse or transfer location.

When your forklift passes an embedded positional floor tag for pick-up, the RFID reader sends positional data to EVS144, which can choose to send on the position to the onboard computer right away or to hold on to the information until a barcode is scanned and at that time send on both positional and item codes as one packet to the onboard computer, and onward to your WMS server for further placement instructions. The floor tag on the placement position can then be read on approach for confirmation of successful delivery.

Ident System AB EVS144 code readers are a code reader series that is easy to install because of its small dimensions. While both EVS144 models are made for rough outdoor use, the EVS144 Imager excels in strong daylight situations, even where direct sunlight is present. The EVS144 Line Camera, on the other hand, is made for high reliability in low light environments and can if needed be equipped with an external spotlight. Both models have a joystick-controlled movable read-head which makes them suited for both fixed mounting such as entrance areas or conveyor belts, or forklift mounted.the long reading distances, depth of sharpness and ability to read a wide range of codes as well as inverted codes, codes punched in metal sheets or low quality printed codes makes this a truly versatile series for use in harsh environments where reading conditions and/or a large flexibility to read a range of code types and object sizes are present.

In our series of Identification systems in the Logistics Industry, we have now covered Barcode and RFID readers. In this last newsletter in the series, we will be briefly discussing how it all can fit together and some of the surrounding equipment IdentSystem can provide. As mentioned earlier we will discuss RFID tags in a separate newsletter next week from a more general perspective. Fitting a whole system together will naturally depend totally on your own individual processes and setup, we will now present one example of how it can tie together. A smaller delivery truck comes in with packages intended to be sent to the same destination. As they are offloaded, the Barcodes on each package is scanned and registered and sorted to a pallet intended for that destination. The pallet, when filled, is then coded as a separate item and when picked up by the forklift its barcode is read by a forklift mounted scanner. The tags data is sent to the WMS and in return the driver gets a destination point on his truck terminal, telling him which container he will offload the pallet in. When he reaches the container, its position is read by an onboard RFID scanner with an antenna mounted under the forklift. The RFID tag with location data is embedded in the warehouse concrete floor. When the pallet is offloaded in the container, the driver closes the work order and get informed where to pick up the next pallet. If however the location ID of the RFID tag read at the container is not the intended one, he will not be able to close the process and instead get an error message telling him to deliver the pallet to the right container. So now we arrived at the last section of this newsletter and will present the accessories Identsystem has for extending the usage of our readers in different ways. First out is the Master/Slave cable for EVS138 which allows two EVS138 barcode scanners to be connected to one Main unit. This can be done for two reasons: 1) letting them work as one wide range scanner and cover a wider area then is possible with only one scanner. For example on very wide forklifts. 2) letting them work in tandem where faults in reading cannot be allowed and compare the data read by each camera to confirm that correct data is read. Second is our EVS-SPC (Smart Protocol Converter), which in its basic setup is configured as a Serial data converter for RS232. It can convert from one baud rate to another, change stop bits, etc. We choose this to be a modular build so that other features could be installed on request. Such features are: Keyboard emulator, ZIOX host controller, Logic controller with built-in ID translation database – for example where you have to upgrade the tags in your system but the ID:s doesn’t match the values of the previous tags – the EVS-SPC reads in the data from the new tag and translates it to data used by old tags. On request, this EVS-SPC can be customized to match most of your needs.

Barcode solutions for rugged environments.

For outdoor use, or in timber industry where the wood has to go into heated drying chambers, we can offer rugged barcodes that will not easily be damaged or faded.

With these barcodes we suggest using our EVS138 reader for outdoor use since it handles a wide range of weather conditions as well as strong sunlight.
Indoors in low light conditions, EVS144 is the recommended choice.
