Configuring the KF3
Chapter 3
3Ć10
Before connecting the KF3 to your network, cycle through the parameter
settings. If you have properly defined your network needs, you know what
parameter settings your network requires. Compare the parameters you
need for your network to the settings in the module. If you have made
no changes to the default settings, the values shown in parentheses in the
Factory Default column of the Tables 3.B and 3.C should appear in the
displays.
When you connect the module to your network and turn it on, the displays
will cycle through the numbers 1-3 and then turn off. If your DH-485
parameters are correctly configured, the DH-485 Activity LED on the front
of the module will light up. If the Fault LED lights up instead, check your
station address, as stated in Parameter Number 0, Table 3.B. If no lights
come on, check your DH-485 Baud Rate setting (Table 3.B, Parameter
Number 1).
Once you initiate active communication on the DF1 link, the RS-232
Activity LED will light up. If this fails to happen, check your RS-232C
parameters (Table 3.B, Parameters 3-8).
If your displays show symbols other than those shown in this chapter, your
module is malfunctioning. Contact your A-B representative.
