The factory default for the communication parameters is:
Baud rate = 9600
Address = 1
In a network, the baud rate must be the same for all instruments, and each instrument must
have a unique address.
The Configurator can talk to any Field Logger in the network, addressing one Field Logger at a
time. After selecting a new address, and clicking in “Read Configuration”, the parameters of the selected
Field Logger are read into the Configurator.
To configure other Field Logger parameters, go to the Channels page. A screen similar to
figure Channels Page is shown below.
7.2 Channels Page
In the “Channel Selection” box, choose a channel to be configured. The parameters shown on
the right side of the screen refer to the channel selected. The channels marked “Enabled” will be
monitored (on-line monitoring) or logged into memory. A 16 character field (Title) is available for
identifying the application. In addition, each channel can have a tag associated to it, up to 8 characters.
The 8 input channels are universal, and it is allowed any combination of input types, that is,
each channel can be configured independently from the others.
Channel Page
It is possible to adjust the indication range for the linear inputs (4-20mA and 0-50mV) by setting
values to the high and low limits (-1999 to 9999).
For example, when a 4-20mA input is being used and the range is set to 0-4000, the Field
Logger will convert a value equal to 2000 for an input of 12mA. In addition, one can choose the number
of decimals and associate an engineering unit to that input.
For Thermocouples and Pt100, the ranges are fixed and represent the indication span of the
sensor. The selection of the temperature unit (C or F) is available for these sensors. Each channel has
