Version 6.0
EAGLE QUANTUM PREMIER DEVICES
Serial Ports 1-4
These ports can be used for communication with a host device such as a users Distributed Control System
(DCS), Programmable Logic Controller (PLC) or Human Machine Interface (HMI).
Ports 1 and 2 use the RS-485 standard, 3 and 4 use the RS-232 standard. Each have four configurable
parameters; protocol, baud rate, parity and address.
Protocol
This serial port currently supports the Modbus RTU slave protocol and the drop down menu allows the selection
of either “Not Used”, “MODBUS Slave” and “MODBUS Master”. Port 3 can also be set as a configuration port,
or a second S
3 monitoring port.
Option Board Baud Rate
The motherboard ports speed can be adjusted in standard intervals between a high speed of 115,200 baud and
a low speed of 2,400 baud. 19,200 baud is both the default setting and the most commonly used setting for
connection to Modbus compliant devices. Ports 2-4 on the Type-A expansion board have a speed range of 9,600
to 230,400 bps.
Address
The address field is for entering the desired Modbus station address. The default value is “1” and it can be
changed by using the “up/down” arrows or direct entry of a value. The Modbus station address must be in a
range from 1 to 247. Addresses above 1 are typically used in multidrop systems.
Miscellaneous
This section of the “Configure a controller...” dialog box has three adjustable parameters; setting of the controller’s
built in “beeper” volume, LON point disabling and access to the user parameter editor.
Beeper Volume
The Eagle Quantum Premier controller has an integral “Beeper”
to annunciate a variety of conditions and to meet regulatory
requirements.
To accommodate the controller being mounted in areas with different amounts of ambient noise the beeper can
be adjusted to any of three settings; Low, Medium and High, via a pop-up menu. The default value is “Low”
which is suitable for installations where the controller is not in a separate enclosure and is in a control room/office
type environment.
User String Display
Check the “User String Display” to allow the descriptor entered in the “Misc” field to be displayed on the
controller.
