If a satellite controller was accidentally addressed #8, there will
be a satellite number missing. For example, if satellite controller
#16 was mistakenly addressed to #8, satellite controller #16 will
not be present. One way of telling which satellite controllers are
“on-line” is to go to the Satellite Summary Screen (see Section
3
) and see which satellite controllers the computer recognizes as
being “on-line.”

If satellite controller #8 was accidentally misaddressed #16, there
would not be a satellite controller at address #8, and the computer
will give a “Non-Existing” message for satellite controller #8.

The Other Dipswitch on the SAT 3D

Option 1, 2, and 3 Switches

For the SAT 3D these Options switches do nothing, but on the SAT
III controller the option 1 switch selects the A to D converter type
that is on the mother board. With the switch turned OFF, the A-to-D
curve is selected for the Maxim MAX147 part and with the switch
turned “ON” for the TI-ADS7844 (BB marked), the software will
use the special A-to-D curve for the TI-ADS7844 part.

BATT ON/OFF switch

This switch is used to turn the Battery (Rechargeable Super cap)
ON and OFF to the SRAM located inside of the SAT 3D.

Local Set Switch

When the LOCAL dipswitch is in the ON position, the TUC
controllers will operate according to their predefi ned user
programmed “local set” setpoints. That is, if the TUC controllers
were programmed by the user to correctly operate when and
if the WCC III - MCD is off-line or disconnected, but the SAT
3D controller is still present and communicating with the TUC
controllers.

Local Set Disable Switch

When the LOCAL SET DIS dipswitch is in the ON position, the
TUC controllers will operate according to their predefi ned user
programmed “On” setpoints. That is, if the TUC/RTU controllers
were programmed by the user to correctly operate when and
if the WCC III - MCD is off-line or disconnected, but the SAT
3D controller is still present and communicating with the TUC
controllers.

Test Switch

The test mode is active only if the TEST dipswitch is in the ON
position. The word “TEST” can be input as the binary value within
the SAT 3D. Example of use would be if the user programmed
the word “TEST” into one of the control point values in the TUC
controller to check the operation of the TUC controllers with an
alternate setpoint or schedule, the user could then place the TEST
switch in the ON position to make this function work without
physically having to go back to the front-end computer to change a
setpoint via the computer.
