Main PCB

The IND246 terminal's main printed circuit board (PCB) provides the analog load cell scale
interface, as well as the COM1 RS-232 serial port. The IND246 POWERCELL main board provides
the load cell interface and a standard COM1 RS-232/RS-422/RS-485 isolated serial port.
The main board also contains the power input connection (for either AC supply or battery,
depending on the model), display interface, keypad interface and six-position DIP switch.
An SD memory card socket is mounted to the PCB to support the optional SD memory and bus
connectors are included for the option boards.

SD Memory

An SD Memory card is included as a standard feature of the analog version of the IND246, and is
available as an option for the POWERCELL version. The card provides a medium on which to store
files such as Alibi memory, transaction records in the vehicle application, IDs in the counting
application and target weights in the checkweighing application.
The SD memory can be used to extract and save the configuration and calibration settings of the
terminal. These can then be restored to the terminal or loaded to a different terminal.

Scale Bases

1.9.1.

Analog

The standard IND246 terminal supports analog scale bases and provides either 10 volts (AC
version) or 5 volts (battery version) of excitation to drive analog load cells. Up to four (battery
version) or ten (AC version) 350Ω load cells can be powered by the terminal.
A six wire load cell connection is provided with sense lines to help maintain accuracy as the load
cell cable resistance changes with temperature variations.
1.9.2.

POWERCELL

The IND246 POWERCELL terminal supports scale bases that use POWERCELL PDX, GDD,
SLC611D or SLB615D load cells. Up to 12 load cells can be configured in a single scale platform.
The load cell network provides monitoring and logging of a variety of factors that can affect system
integrity, including weighing errors, overloads and network health. The specific characteristics differ
by type of load cell.
