SCALE - Setup and Configuration

Latest Update: 3/12/2011

A Legal-for-Trade Integrated Scale is the key to ensuring accurate, compliant sales with a single push of the button. There are few scales with the appropriate level of integration and interface, and MJ Freeway has taken the time and research to make sure that the correct, easy to use solution was provided for our clients.


Basic Requirements

As mentioned previously, there are very few integrated scale solutions that provide for the correct integration (software) and interface (hardware), and MJ Freeway has pinpointed that solution through arduous research.

Nonetheless, as newer solutions appear in the market, they may provide additional options. Here are the basic requirements to look for before attempting an alternative solution:

  • Direct USB / Keyboard Interface, or RS232-to-USB Interface with COM Port Interface Software:
    • An integrated scale, similar to other compatible MJ Freeway peripherals, needs to be able to speak "keyboard". If the scale only provides an RS-232 (Serial) interface, then an appropriate Serial-to-USB hardware solution (cable) combined with the correct, compatible software to translate the input to keyboard strokes can also work.
    • ** BE CAREFUL ** Do not get 'USB/Keyboard' confused with the USB /HID Interface, as USB/HID is not supported by MJFreeway.com.
  • (Colorado Only) Must provide '.01g' Legal-for-Trade Precision for measuring MMJ:
    • In the state of Colorado, in order to dispense MMJ to fill appropriate prescriptions, a '.01' gram precision level is required by law to be deemed legal-for-trade.

Recommended Hardware

Again, based on extensive research throughout the market, MJ Freeway was able to pinpoint an appropriate solution that has worked with MJ Freeway time and again. Here is the hardware specific to that solution:


Installation and Setup

A scale is one of the most vital parts of a dispensary’s day to day operation, and integrating this scale with GramTracker and GrowTracker can make this process much easier.

In integrating with MJ Freeway’s software, a scale will need to output to a USB/Keyboard format.

If this is the case, simply pressing the proper button (usually marked “Print”) will send data from the scale to the software, keeping weights accurate.

Step 1 – Unpack and Plug In

With a scale that has been purchased through MJ Freeway, or at least meets the requirements outlined in the article INTEGRATED SCALES - HWIS01 - Requirements & Overview installation is quick and easy,

1)      Unpack the unit from the box. Take note of Make and Model number, in case you need support in the future.

2)      Check to verify the output method of the scale. If it is USB, skip step 3. If it is a USB and a MAC, it should be plug and play.

3)      If your scale outputs to a serial cable, one of two steps need to be taken.

  1. If your scale comes with an attachable USB cable interface, not an adapter cable, follow the instructions included in the package to unscrew the metal plate on the back of the scale and attach the USB cable.
  2. WINDOWS POS WORKSTATIONS ONLY! If you have a Mac, you will not be able to use the Serial to USB adapter cable. Please call support.

           i.      If your scale came with a Serial to USB adapter, you will need to affix the adapter cable to the serial cable that comes from the scale.

           ii.      Download and install the Win CT driver tools, located here.

          iii.      Extract the zip file, and double click “setup.exe”.

          iv.      Follow the prompts to install the RSKey Software.

4)      Plug the USB cable into an available USB port on your POS workstation, and turn the scale on.

  1. If your scale is using an adapter cable, and Windows is unable to locate the driver for the device, you can download the driver from here, making sure to select the proper version for your copy of Windows. If you have any doubt about which driver to download, please contact support.
  2. If you are using an adapter cable, start the RSKey software. This can be found in the A&D WinCT folder in your start menu (Do not start the RSCom program). This software will need to be running in order to use your scale.
  3. Select the correct COM port for your scale. If you do not know which COM port your scale is using, you can check Devices and Printers.

Right click the scale, and select “Properties”

Click the “Hardware” tab, this will indicate which COM you should be using in RSKey.

For Windows 10 - On this screen, click "Port Settings" and then Advanced.

On the next page, put a checkmark next to "Serial Printer"

  1. Click the “START” button in RSKey. It will minimize to the Start bar.

Step 2 – Verify the Scale

A properly configured scale should export data in the form of simple text. We can test this by using any program that allows simple text. Typically, we’ll use Notepad on a PC, or TextEdit on a Mac.

1)      Go to Start and type notepad in the Windows 7 search bar. Notepad will come up as an available application to run.

 

2)      Once the Notepad window is open and the cursor is flashing as though you were going to type into the document, place an item on the scale and wait for the scale to normalize.

 

3)      Press the “Print” button on the scale. If the scale is working, then the result should be a string of text that includes the weight displayed on the scale. The cursor should also now be on the next line, beneath the text.

Step 3 – Using the scale with GramTracker

Start by logging into your MJ Freeway account with your username and password.

If using an adapter cable, make sure that RSKey is running, and “START” has been clicked.

1)      Type the first or last name of a patient into the first or last name fields, and click “Search by name”.

2)      Click the “Start Order” link for that patient.

3)      Select a product that has been marked as “Sell by Weight” (most of your MMJ is likely sell by weight).

4)      In the weight selections screen, click in the “Quantity to Charge to Patient” field.

5)      Place the item to be sold on the scale and a weight to be displayed. Most scales have an indication when then displayed weight is steady.

6)      Press the print button on the scale.

7)      If properly configured, the same value will populate in both the “Quantity to Charge to Patient” field, as well as the “Quantity to Deduct from Inventory” field.

8)      Make any necessary adjustments, and click “Add To Order”.

    When using the push button tare (or zero) feature, the weight of the tared item will reduce the capacity of the scale by that amount.

     

    For example:

    Assume your scale has a capacity of 1200g.

    If you place a 400 gram container on the scale and then press the re-zero button, the scale will only weigh up to 800 grams.
