Relays 1-6 are wired into sensor inputs 1-6. They commutate "Vin", which is the
voltage from the power source for the DS1005. When a relay is activated, this
voltage is applied to a corresponding sensor input.
There are eight sensor inputs but only six relays. Remaining sensor inputs 7 and 8
are controlled by two buttons which play the same role as the relays. Push a button
and a corresponding sensor input is triggered.
Setup (MD) Button (Line)
Tibbo boards and external controllers (such as the
) have a
button called "setup" or "MD" button ("MD" stands for "mode"). Tibbo modules (such
as the
) have an MD pin (line).
The setup button (line) has three functions:
·
When a Tibbo BASIC/C application is running, it can use the button for its own
purposes (see the button. object).
·
When the device is password-protected, keeping the button pressed (line pulled
LOW) while accessing the device from TIDE allows the password to be bypassed.
This is the way to reset the password on the device.
