6 NewStep Controller ASCII
Command Set
6.1 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. If the incoming message does not have a matching address, the
controller will ignore the message. When a controller receives a command that
matches it’s address, depending on the message (query or set) it may or may not
respond back. If the Controller responds back, it will first send out the command
it received followed by the information it is to send.
For example, if a 234VE? Is sent to Controller Number 234, it will respond as
234VE? 1.0.
