Main PCB

The IND780 terminal's main printed circuit board (PCB) includes provisions for the
microprocessor, main memory, battery, application module key, Ethernet, USB and
serial communications, and mounting of option boards.
The main board contains the COM1 and COM2 serial ports. COM1 provides RS-
232 communication, while COM2 supports RS-232, RS-422, or RS-485
communication. These ports are bidirectional and can be configured for various
functions such as demand output, SICS host communications, continuous output,
ASCII command input (C, T, P, Z), ASCII character input, report printing, totals
printing, or connection to a remote ARM100 module.

Scale Bases

The IND780 supports Analog, IDNet, SICS, POWERCELL and POWERCELL PDX
bases.

Analog Load Cell Scale Base

The IND780 supports this scale type through an analog load cell interface. The
terminal can drive up to sixteen 350-ohm analog load cells, with up to eight 350-
ohm load cells on one channel.
IDNet
The IND780 supports both the newer T-brick style of high-precision base and the
older "PIK-brick" transducers, through the IDNet scale interface. For T-brick bases,
the interface provides the +12 volts and communication required to operate this
newer style of base. The port also provides +30 volts, to support PIK-brick high-
precision bases. The base's cable determines which voltage is used.

SICS Scale Base

The IND780 supports Mettler Toledo high precision scales and balances that utilize
the SICS communications protocol. These scales and balances are branded as the
Mettler Toledo Excellence balances, X-bases/platforms, WM/WMH and 4-series
scales (BBx4xxIND4xx). The SICS scales are connected to the IND780 via the
serial interfaces. Four SICS scales can be supported per terminal, when optional
Serial boards are installed. Depending on the type of SICS scale connected,
different configuration settings will be available in the IND780 terminal setup
screens.
POWERCELL
The IND780 supports scales that use the POWERCELL communications network
found in large hopper / tank applications as well as vehicle scales that use the
