2.5.2. Discrete I/O PCB Switch
Each of the four different DIO option boards includes one slide switch. This switch is used to select
between active inputs (for which power is supplied internally by the IND570) or passive inputs
(which require an external voltage supply).
Ensure that the switch is set properly before wiring to the inputs. The switch locations and the
settings are shown in Table 2-12.

Switch
SW1-1 Metrology Security Switch (legal for trade).
When in the ON position, this switch reduces Administrator
access to Maintenance level which prohibits access to the Scale
block in the menu tree and other metrologically significant areas.
This is true even if no scale approval option is selected in setup.
SW1-2 Flash Software.
Set in the ON position during software download
Set in the OFF position during normal operation
SW2-1 Factory test.
Set in the OFF position at all times for normal weighing. This
switch must be ON when connecting to the InSite CSL program
using the COM1 serial port of the IND570 terminal.
SW2-2 Factory test.
Set in the OFF position at all times
When both SW1-1 and SW1-2 are positioned ON and AC power is applied to the terminal, a
Master Reset function will be initiated. This procedure will erase all programming in the terminal
and return all settings back to factory default values. This process is described in the User's
Guide Chapter 5, Service and Maintenance.
