Scale Bases; Options; Com2 Serial Port - Mettler Toledo IND246 Guide D'installation

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.

Scale Bases

The 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 eight (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.

Options

The following options are available for the IND246:

COM2 Serial Port
This optional port provides RS-232 and RS-485 communication at rates from 300
to 115.2k baud. The port is bidirectional and can be configured for various
functions such as demand output, continuous output, extended continuous output,
SICS host communications or ASCII command input (C, T, P, Z).
