IND780 User’s Guide

1-9

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

™

Scale Base

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

™

Scale Base

The IND780 supports scales that use the POWERCELL communications network

found in large hopper / tank applications as well as vehicle scales that use the

1 2 ... 15 16 17 18 19 20 21 22 23 24 25 ... 128 129
