Setting Up Communications Parameter Data
Set the Bulletin 900 controller communication parameter specifications so that
they match the communication parameter setup for the personal computer,
using configuration/monitoring software such as 900BuilderLite. In a
multidrop (RS-485) 1:N configuration, match the setting data except for the
communications unit numbers on all 900-TC controllers. All Controllers must
have unique communications unit numbers.
✟
The Communication Data Length and Communication Stop Bits parameter is displayed only when 900-TC
communications are selected from the Protocol Setting parameter.
Initial Setup Examples
The
O
and
M
keys are used to switch between configuration menus, and the
amount of time that you hold the keys down determines which configuration
menu you move to. This section describes two typical examples.
