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 2-6.

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 Chapter 5,
Service and Maintenance.
