Serial Port Interface for the MS2320 integrated scale:
These general instructions and practices are referencing the Metrologic Stratos Series integrated in counter scanner scales. Other scanner / scales are supported that use dual cables and NCI ECR scale protocols. Plexis POS supports many Stand Alone and Integrated Weight Scales connected to an RS232C Serial Port. Use a true RS232C Serial Port Adapter. Many Consumer based home computers that customers try to use in a business environment do not come standard with genuine RS232C serial ports. USB serial ports are not true RS232C. USB to Serial Port converters tend to truncate data depending on the driver and chip set. If you use a USB to Serial converter make sure that it supports true RS232C standards, otherwise the weight scale may not work properly. Point of Sale Business Computers are typically designed to have genuine RS232C serial ports installed and will work perfectly with our supported ECR weight scales.

MS2320 Scanner / Scale Hardware Requirements:
1. Plexis POS Supports many Scanner and Scale Models using the NCI and Mettler-Toledo Scale Protocol.
2. DUAL Cables are required, one for the scale and one for the Scanner.
3. The Scale uses a standard RS232 Serial cable. The Scanner can be Keyboard, USB or RS232 Serial.
4. These examples are specific to the Metrologic MS 2x2x Series in counter Scanner / Scales.

Setting Up the MS2320 Weight Scale:
Test the weight scale through the Plexis POS interface by choosing from the Main System Menu: Utilities, Diagnostics then Weight Scale. Configure the Weight Scale port so that it matches the proper Serial Port Number. Press F2 and verify you have had a successful test. Once tested choose Save.

Note: Some scales send large packets of data all at one time. These scale formats may only be reliably used with a quality HIGH SPEED RS232 Serial Interface.

Suggested Solutions:
1. Replace your Serial Port adapter with a HIGH SPEED Serial Adapter or Converter.

2. As a possible alternative, go to the Windows Control Panel under System, Hardware, turn OFF FIFO and LIFO support on the serial port you are using. Contact your computer hardware expert for more details if needed.

NTEP Certification:
Plexis POS supports numerous scale models directly connected to the computer. Tare-out is supported. Direct connect scales will automatically enter the weight into the POS system and calculate the price. Be aware that Plexis POS is not NTEP certified and if your community requires software to be certified legal for tender you will not be able to connect the scale to the computer. In this case you can use a stand alone scale then enter a weight manually on the Sales Screen or Touch Screen and Plexis POS will calculate the total sale price automatically. Type 2 Embedded Price barcodes are also fully supported.

Note :
Plexis Software Systems does not sell or support computer systems, networks POS Peripherals or any other hardware.
