Setting Up Cash Register and Display Pole

Wavelet EMP Point of Sales is able to integrate with cash register and display pole at the cashier counter. Please follow the steps below to make things work:

Note: This setup is applicable to TRADING -> FULL SCREEN CASHSALE only.

 

Second Serial Port for Point of Sales PC

Most PC only comes with one serial port (RS232). As the display pole and the cash register both require RS232 to connect to the POS computer, we would need a USB to RS232 converter. Once you have installed the USB driver for this converter, please be sure that you go to the control panel, and system hardware to check the COM port number assigned to this USB device, normally it is COM3, but it could also be COM4 etc.

Connect the Cash Register to COM1 (serial port) of the Point of Sales PC

After you connect the cash register cable to the PC at the Point of Sales, ensure that you test the connectivity, by using a DOS command prompt:

1) Create a text file using notepad with, and save it inside c:\wavelet (create the directory if it does not exist), we call it serial_test.txt

     The text file should have the following text inside: 000000000

 

2) Type the following DOS command to send serial_test.txt file to the COM1 (RS232 serial port):

 

     cd c:

     cd wavelet

     mode COM1:300

     copy serial_test.txt COM1

 

If the cash drawer opens, you have successfully connects the Cash Register to COM1 of the PC, otherwise get it to work before you proceed to the following steps.

 

Connect the Display Pole to COM2 (serial port) of the Point of Sales PC

If you have a display pole that you would like to show the prices as the cashier scan in each item, and subsequently as the total amount and change amount, you can connect a display pole to the second serial port of the PC at the point of sales.

 

The Applet/Plugin Configurations

If the plugin/applet above does not work, follow the instructions below, the instruction is also available at TRADING -> FULLSCREEN CASHSALE (scroll to the bottom):

 

  1. Download and install MOZILLA web browser from http://www.mozilla.org/download
  2. Download and install J2EE SDK 1.6.0  from Sun Microsystems website. During installation, select CUSTOMER, and set  the installation directory to C:\j2sdk1.6.0\ (We call it JDK) in the Windows environment
  3. Download java.policy and save it inside JDK\jre\lib\security
  4. Download comm.jar and save it inside JDK\jre\lib\ext
  5. Download javax.comm.properties and save it inside JDK\jre\lib
  6. Download win32com.dll and save it inside JDK\jre\bin

 

Configure the JRE Settings

After you have installed the Applet/Plugin above, power up mozilla web browser, and login to Wavelet EMP, click TRADING-> FULL SCREEN CASHSALE for the Point of Sales interface. As the applet is embedded in this page, it will trigger the JRE to be activated. You should see a small coffee cup icon, open up the control panel, and make sure that the JRE is pointing to the right directory. This is because during the installation of the mozilla, the default JRE may have been installed in the system, but we do not want to use the default JRE, we would like to make use of the newly downloaded and installed JRE, with the various configuration files, dll etc properly in place as per above instructions.

 

Trouble Shooting

To troubleshoot for errors, if the applet is not working properly, you can click the coffee cup icon on the system tray (bottom right hand corner of your windows desktop), and open up the console.

 

Display Custom Text : Welcome etc

This feature is still under development, once developement is completed, users will be able to configure welcome message under SYSADMIN -> CONFIGURATIONS -> POINT OF SALES.

Upon successful completing a transaction, the display pole would be able to display some text, like : "THANK YOU, PLEASE COME AGAIN" or "WELCOME TO COMPANY XYZ".
