POS WEIGHT SCALE SETUP

ECR Weight Scale Hardware Requirements:
Plexis POS Supports many of the NCI Series ECR and Standard Weight Scales.
Consult our Supported Hardware page for details HERE.

Serial Port Interface:
Plexis POS supports Weight Scales connected to a 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. We have had limited success with USB interfaced weight scales where the manufacturers scale port driver creates a virtual serial port.

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.

Setting Up an ECR 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.
Proper Output Example for an NCI 6720 ECR Mode:
(10)00.430LB(13)(10)S00(13)(3)

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.
