Configuration Before Installation

NOTE
VAISALA ________________________________________________________________________ 19
This chapter provides you with information that is intended to help you
install the GMW90 series transmitters.
If you need to change the settings of the transmitter, it is best to do this
before it has been installed. Available configuration options are different
for analog output models (such as GMW93) and digital output models
(for example, GMW95).

Configuration of Analog Output Models

You can configure analog output models of GMW90 series transmitters
in two ways:
- Using the DIP switches on the component board. See section DIP
Switches of Analog Output Models on page 20.
- Configuring the settings in software through the service port. See
connection instructions and serial line commands in Chapter 4,
Operation, on page 31.
These two configuration methods are mutually exclusive. If the DIP
switch configuration is used, software settings have no effect on settings
that are controlled by the DIP switches. Additionally, standard analog
output settings and display configuration are always set in the DIP
configuration mode. DIP switch number 8 is the master switch that
controls which configuration method is used.
Software version 1.3.1 for analog output models introduced an exception
to this. If you have used the AOVER command to configure the behavior
of analog outputs when the measured value is outside the scaled output
range, your AOVER configuration remains even in DIP switch
configuration mode. See Set Output Clipping and Error Limit on page 45.
