The
Select Input (Serial)
dialog box opens.
6 Select the system you want to interface from the list provided.
Every interface is presented as a small "block diagram".
Note
Just adding an external device does not mean it is properly working. It is very
important that any serial line between the TV80 and any external system is setup
correctly with identical parameters at each end. The
Serial Port Setup
dialog box
allows you to define the communication parameters for serial line ports.
7 Click on the relevant serial port icon to open
Serial Port Setup
dialog box.
8 In the
Serial Port Setup
dialog box, define the relevant parameters for the
communication. Click
OK
to save the chosen parameters and close the
Serial Port
Setup
dialog box.
9 Repeat for each sensor interface that you need to set up.
Checking the data transfer on a serial line
The communication between the Processor Unit and peripheral devices takes place using
"datagrams". These datagrams are self-contained and independent entities of data carrying
information. When setting up or maintaining the TV80, it is always useful to verify that the
communication lines with external devices are operational.
Prerequisites
This procedure assumes that a receiver has been connected to the Processor Unit by
means of a serial line, and that the communication line has been initiated. All the relevant
communication parameters have been defined. The external sensor is powered up, and
transmits data.
