  • Page 35: Figure 9 Initializing Controller Screen

    Software After selecting the Port, if the Program finds any Uninitialized Controllers(Controller address equal to zero), the “Initialize Controller” window will open. The user then has to choose a valid controller address (a non-zero value) that has not been assigned to other controllers. NOTE When initializing, only one Uninitialized Controller may be connected to the network at a time.

    NewStep Controller ASCII Command Set Command Summary This document describes the supported two-letter ASCII commands that may be used to configure and operate the NewStep Controller, when in REMOTE mode (Yellow LED). Since multiple NewStep Controllers may be placed on the RS485 Bus, each controller will use a predetermined address (Controller Number) and by decoding the address field of the incoming messages, it can determine if the message is intended for it.
