BAUD RATE AND WEIGHT MODE SELECTION
The AS-400D and AS-410D can be operated in either a pounds/ounces mode or UPS pounds
only mode. A setup switch makes this selection. The AS-420D operates only in a pounds
mode and cannot be set to a pounds/ounces mode of operation.
NOTE! Although the AS-420D operates in a pounds only mode, it does not use
the UPS pounds only command set.
Switch S1 (2, 3 and 4) are used to select the baud rate for serial communication via the scale
port. Switch S1 (1 and 5) are used to select the weight mode.
To gain access to the switch S1:
1. Unplug the scale from the power outlet.
2. Remove the stainless steel platform.
3. Once the platform has been removed, you will see the switch located on the main
printed circuit board.
4. Using a small screwdriver or similar device, set the five switches to the desired setting
as indicated in the table.
5. Replace the scale platform, and then plug in the power cord. This will reset and restart
the scale for normal operation.
