Connecting to the Ticketing App
In Fast-Weigh Ticketing, go to Server Settings.
(You must have appropriate User Permissions to access these settings).
Under the Manage Devices area, select Add Device.
For the Device Type, select IP Scale.
IP Scale Setting in Fast-Weigh Ticketing. Name the device as you wish.
Enter the IP/Network Address and Port number set to the Moxa device.
If your Moxa device has an IP address of "192.168.0.11", then you would enter the following in Fast-Weigh:
http://192.168.0.11:4001/
The following settings usually do not need adjusted except in special cases:
Format Type: Typically left as CR or Linefeed.
Use Buffer: Typically left disabled.
Set the appropriate Weight Type:
Gross, Net, or Hopper.
Set the Indicator Units according to how your scale indicator displays:
Pounds, Kilograms, Tons, or Tonnes
To finish up, select Add IP Scale.
The last three options are not always necessary to adjust and we will cover those shortly.
Lastly, under Manage Lanes, use the drop-down menu to assign the new scale to the appropriate Lane.

With the scale connected, it should be displaying weights in the application in both the ticketing area and the Server Settings devices.

The Status should show Green to indicate a connection is available. The Test buttons are for the following purposes:
Pause button: Close the device connection in Fast-Weigh.
Play button: Open the device connection in Fast-Weigh.
Hourglass button: Test the device connection and data communication.
Scale Accuracy Adjustment
If the scale weight is coming through incorrectly in Fast-Weigh, then we may need to adjust the "Characters to Read" and/or "Gross In Position" settings for the device.
To do so, select the device from the list in Server Settings.
You should now see a Blue Magnifying Glass in the device settings.
Click the Blue Magnifying Glass to have Fast-Weigh try to auto-detect the best settings for the scale.
You should see a notification pop-up that says: "Checking for Repeating Pattern".
Once complete, you'll have a pop-up displaying the results of the check.
The final two lines are very important, as they will reflect the two numbers that should go in these two fields.
Selecting "Set Characters To Read" will automatically apply this information to the device settings in Fast-Weigh.
Repeating Pattern Check Results This should correct most inaccuracies you will see in the scale weight displaying in Fast-Weigh.
Scale Stability Adjustment
If you notice that the scale weight is "jumping" or not showing a stable weight, then it may be worth using the Scale Stability settings in Fast-Weigh for the device.
To do so, select the device from the list in Server Settings.
Enable the "Use Scale Stability" setting.
Scale Stability device settings. These two settings can be adjusted to accommodate the scale weight not staying steady at all times.
Stability Count: The number of seconds a weight from the scale must be within the weight tolerance to be considered stable. (Minimum 4 seconds, Maximum 15 seconds)
Weight Tolerance: The amount of weight that can change before the weight is considered unstable. Set as a percentage of the weight in decimal form. (Minimum 0.00, Maximum 0.05)
