Identifying the Scale

Prior to configuring the scale, it is important to determine which Mettler Toledo Scale you are using. The Viva and Ariva scales require different serial adaptors and have different firmware settings. To determine the model of the scale, look for the label on the scale with the model information. The label is either on the side or underneath the metal top.

Required Equipment

The following equipment is also required:
  • Lantronix xDirect Serial to Ethernet Device Server

Configuring the Mettler Toledo Ariva Scale

There are five steps to configuring the scale for use with the NCR Silver Pro Restaurant app: confirming the scale firmware settings, setting up the hardware, locating the Lantronix xDirect device IP address, configuring the Lantronix xDirect device, and configuring the settings within the NCR Silver Pro Restaurant app.

Important things to keep in mind:

  • When using a web browser to access the Lantronix xDirect device, the recommended browser is Google Chrome. Do not use Safari or Internet Explorer as they are not compatible.
  • If you are configuring multiple scales for use in your restaurant, only configure one scale at a time as this will make it easier to locate the IP address for the Lantronix xDirect device.
  • Prior to beginning, you will also need the username and password required to log into your network router.
  1. Confirming the scale firmware settings.
In some cases, it is necessary to update the firmware settings. 
  • While turning on the power, press and hold User-added image key until ‘grP 1’ is displayed.
Use User-added image  to confirm the choice and move to the next step.
Use User-added image to accept the soft switch settings.
  • For each group, confirm the following. If your scale settings do not match, then change as indicated:
3.1Communication Type0 (RS-232)
3.2Baud Rate3 (9600)
3.3Parity1 (Even)
3.4Data Bits0 (7data bit)
3.5Stop Bits1 (1 stop bit)
3.6Production Selection3 (8217 Mettler Toledo)
  • After the last setting, press  several times until Save appears and then press a final time to save the selections. The scale will reboot.
