Main PCB

The IND570 terminal's main printed circuit board (PCB) provides either the interface for analog
scales/load cell(s), SICSpro platforms or IDNet platforms.
The main board also contains the USB Host port for connection of an external keyboard or barcode
scanner for data entry or a USB memory device that can be used for data collection, file transfer and
system backup.
A single standard serial port (COM1) is located on the main board and provides RS-232, RS-422,
or RS-485 communication. The COM1 port is bidirectional and can be configured for various
functions such as demand output, remote display, SICS host communications, continuous output,
ASCII command input (C, T, P, Z), ASCII character input, report printing, totals printing, or
connection to an ARM100 remote I/O module.
The main board also contains an input from the AC (or DC) power supply, front panel keyboard
interface, and bus connectors for the option boards.
Current limiting for the IND570xx version is also located on the main board.
