Configuring the Communications
Controller
Chapter 3
3-5
Important: If you change any of the RIO parameters (see Table 3.B)
and then press VIEW and EXIT, the display cycles through the
numbers 1–3 after showing the three dashes. This indicates that the
Communications Controller has saved the new parameters in
non-volatile memory, and then gone through a reset cycle to bring the
new parameters into effect.

FAULT
If the save is not successful, the Communications Controller is
malfunctioning. The left display will show hardware fault number 6
(see Table 5.C) and the fault indicator will light. If this happens you
should contact your A-B representative.
Exit Without Saving
Press only the EXIT button while in the main menu to take the
Communications Controller out of configuration mode and into run mode
without saving any changes. This ends the configuration session and the
previous settings will remain in effect.
