Product Related Safety Precautions
The SPS311 delivered to you has been tested for safety and approved
as shipped from the factory. Note the following precautions:
WARNING Ground the product, and verify outdoor installation grounding
periodically to minimize shock hazard.
CAUTION Do not modify the unit. Improper modification can damage the
product or lead to malfunction.
ESD Protection
Electrostatic Discharge (ESD) can cause immediate or latent damage
to electronic circuits. Vaisala products are adequately protected
against ESD for their intended use. However, it is possible to damage
the product by delivering electrostatic discharges when touching,
removing, or inserting any objects inside the equipment housing.
To make sure you are not delivering high static voltages yourself:
- Handle ESD sensitive components on a properly grounded and
protected ESD workbench. When this is not possible, ground
yourself to the equipment chassis before touching the boards.
Ground yourself with a wrist strap and a resistive connection cord.
When neither of the above is possible, touch a conductive part of
the equipment chassis with your other hand before touching the
boards.
- Always hold the boards by the edges and avoid touching the
component contacts.

Chapter 2 ________________________________________________________Product Overview
VAISALA _______________________________________________________________________ 15
The default setting of the switches is shown in the following table.
Table 4 Power DIP Switches Default Setting
Switch No. Default Setting Description
S2-1 ON Signal PTOGGLE1#. When the front
power switch is pushed, the PTOGGLE1#
signal is set to Low. The unit is then
switched ON by the power control logic.
If the setting is OFF, the front power
switch is disabled. This option is useful for
AUTOSONDE and remote use.
S2-2 OFF Signal PON#. Remote PON# functions
normally. Remote control capability is
available with the Power CTRL connector.
If the setting is ON, the unit is always on.
This option is useful for AUTOSONDE
use. The unit is switched on automatically
after a blackout.
S2-3 OFF Signal POFF#. Remote POFF# functions
normally. Remote control capability is
available with the Power CTRL connector.
If the setting is ON, and S2-1 and S2-2 are
ON, the unit is always on. Pushing the
front power switch resets the unit.
S2-4 OFF Not used.
S3-1 OFF Signal RACK0#. S3-1 and S3-2 can be
used to identify the units, if multiple units
are used. See Table 5 below.
S3-2 OFF Signal RACK1#. S3-1 and S3-2 can be
used to identify the units, if multiple units
are used. See Table 5 below.
S3-3 OFF Not used.
S3-4 OFF Not used.
Rack address is a binary number formed from signals RACK1# and
RACK0#, where RACK1# is MSB (most significant bit) and
RACK0# is LSB (least significant bit).

Motherboard
The operating voltages as well as signal connections between different
units are carried through Motherboard. The Motherboard is fully
passive. It does not contain any active electronic or electromechanical
components.
I/O Extension Board
I/O Extension Board is a printed circuit board which connects the I/O
signals between the Motherboard and I/O connectors.
Signals to the Connector Panel are fed through an extension board
connector on the back side of the motherboard.
Connector Panel
Connector Panel has connectors for antenna signals, LAN, I/O signals,
and power.
The panel includes I/O Connectors, a printed circuit board which
connects the I/O signals between and I/O Extension board.
Antenna signals and LAN are connected via cables to the plug-in units
and the power inputs are wired from connector to the motherboard.
