Main PCB

1.8.1.

Overview

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.

ETX Board, HMI and LCD Updates

Newer IND780 terminals are equipped with an updated ETX processor, a new color LCD, and a
new HMI board. These updates provide an overall improvement in system performance of 25 to
30%, and a power-saving LED backlight that provides better display readability at all angles.

Scale Bases

The IND780 supports Analog, IDNet, SICS, POWERCELL MTX and POWERCELL PDX bases.
1.9.1.

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.
1.9.2. 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.

The new ETX board (PXA270) is compatible with the existing main PCB. However, in order to
use the updated ETX, the terminal must use firmware version 7.x or above. The existing ETX
board (PXA255) is not compatible with this firmware, and must be used with version 6.x or
below.
The new HMI board and LCD must be used together – neither is compatible with the previous
version of the other. If it is necessary to replace either component in a system currently using
the original HMI and LCD, both must be replaced.
