OPERATION REFERENCES
Using SL2 with SLC2810 Remote
Refer to D4195 SLC2810 Operation Manual for detailed operation, and D4020 Direct Access Numbers for the most
current DAN codes. Some specific operations and features are described below.
Using SL2 with Universal Terminal (UT)
Refer to D4196 SL2 ISO Operators Manual for detailed UT operation, and D4020 Direct Access Numbers for the
most current DAN codes. Some specific operations and features are described below.
*When the SL2 is connected to a UT for the first time, it may take several minutes to load the SL2 mask.
Updating software, storing and loading settings
Refer to D4206 Software Guide for details. Works best with SLC2810, but is possible to do with UT.
*Always save all settings and data first prior to performing any software updates!
While the SL2 is designed to save and restore settings automatically, significant software revision changes may
result in lost settings when not stored ahead of time. The SL2 is also designed to return to a functioning default
setup in case settings are lost, which allows the system to run on both SLC2810 and ISOBUS mask platforms,
without requiring return to a service center.
-Put S19 software file on blank USB (if performing software update). Must be title of ‘image.s19’. Add object pool
file if the mask is also to be updated.
-Remove SL2 cover, insert USB.
-Save Settings to USB. SVSET in ‘Select’ menu, USB down arrow on UT, or use DAN 8713.
-Press reset button on SL2 board, software will now load. May take several minutes.
-Unplug SL2 power for 10 seconds, then plug back in. May take up to 2 minutes to come up on UT.
-UT screen and/ or SLC2810 should now be up in weighing mode.
-Remove USB and replace cover.
-If settings did not automatically load, use LD SET in ‘Select’ menu, USB up arrow on UT, or DAN 8714.

D4204-EN Scale Link 2 Technical Manual 17
Selecting the active scale (multi-scale models only)
SLC2810: Press ‘SELECT’ until SCALE is displayed. Press ‘FUNCTION’ to select available scales.
UT: On the UT screen, touch the scale that you want selected.
Changing Setup & Calibration Numbers
SLC2810: Select the active scale (multi-scale units). Use DAN codes and ‘SELECT’ key to adjust counts, weigh
method, setup, calibration, etc. DAN 8711 and 8712 used for entry of known setup and calibration numbers.
UT: Touch the spinning arrow button above the home key . Touch the ‘Select Scale’ box and choose the scale
to update (multi-scale units). Change Scale ID, Units, Setup Number, Cal Number, or Display Counts as needed.
