Introduction
SyxthSense Cloud Ready Graphics Series Controllers are the most powerful Sedona controllers in the market.
The SDC-xG controllers are fully programmable controllers with flexible BACnet (from Q1 2014), Modbus and
SOX networking. It has been developed based on the open Sedona Framework™ (part of Tridium Niagara™
framework). The controllers are highly flexible to practically any applications and are programmed through
graphical “Workbench” interface, or using open source Sedona programming tools (e.g. CPT Tools). It is
equipped with two 32-bit Processors, the first in the Automation industry, with an ARM9 200 MHz Samsung
processor, an ARM M3 Cortex for the I/O management and A-D processing, and also with a Linux 2.6 OS for
premium performance.
The Graphics Series have a capability to serve up HTML5 Graphics pages that are stored on the Micro SD card.
The graphics are programmed using CPT Tool software that allows Sedona programming objects to be linked to
the HTML5 graphics.
Both SDC-20G and SDC-32G controllers are using the same hardware configurations in term of processor,
memory and etc. and vary in terms of the input and outputs.

Once the input has been set to the correct type using the jumpers, in
the application programming us the Universal Input object and select
the appropriate type.
The SDCxG controllers can support most resistive sensor types. If
temperature measurement is required, use the resistance setting and
link the UI object to Sensor object from the syxthHVAC kit.
easyioSensor kit provides additional sensor object types.
SyxthSense provides resistive sensors to match all resistance curves. Normally with SDC controllers use
NTC10K range sensors such as ECO range (TER-NTC10, TEW-NTC10, TED-NTC10, TEO-NTC10, TESMNTC10, TEF-NTC-10).

6. Universal Outputs
SDC-20G series have 6 Universal Output connections and SDC-32G 8 Universal Output connections. Each
Universal Output can be configured to drive voltage or current output or digital output via hardware jumper setting
and internal register settings. The working range for voltage is 0..10V, for the current either 0..20mA or 4..20mA.
For current transmitter, the circuit able to drive load impedance up to 800 ohm which is ideal for long wire
connection (up to 500 meter wire length).
For digital output it can only support 24VDC and max load is 200mA. AC power source is not allowed. It will
damage the controller.
Once the input has been set to the correct type, further settings are available during the application programming.
Please refer to UO/DO Object section to how to configure the output type.

7. Digital Outputs
The SDC-20G and SDC-32G controllers have 2 and 8 digital 24VAC outputs, respectively. The digital outputs are
volt-free 24Vac relays with the maximum load of 0.5A (maximum voltage 125VAC). The wiring diagram below
illustrates the typical connection.
In the application programming, use the DO object to link the physical digital output to the application logic.
8. RS485 Connection – Modbus and BACnet
RS485 connection must be terminated at both ends with termination resistor, typically 120 Ohms. It is
recommended to use shielded twisted pair wire (STP) for the wiring, such as SyxthSense SS-CAB-2402 Modbus
Communication Cable. For more information please refer to http://www.syxthsense.com/accessories/ss-cab2402/modbus-4-core-24awg-lshf-cable,-100m-/
The Graphics series comes with a build in 120Ohm resistor. To enable this simply change the jumper setting to
ON position. Refer to Jumper Setting section for further details.
Lightning protection circuit is highly recommended to be installed at one end of the wiring. The controller should
be wired in daisy chain network topology as shown as image below. If wire branch can be avoided, keep it as
short as possible, and never connect more than one device to the wire branch(it is not recommended).
NOTE: Be careful if single power supply is used for all connected RS485 device, make sure all devices are having the same
ground connection. Make sure you are connecting the same wire for the same terminal position, all “H” terminals connected to
the same wire.

Controller Application Programming
The SDC Sedona controllers are configured using Sedona Framework libraries and objects known as “kits”. The
configuration is done using Niagara AX Workbench platform (Tridium AX Workbench, Honeywell AX Coach, or
Trend AX TONN), Sedona Workbench (dedicated for Sedona Framework products) or Online Tools CPT tool.
The CPT tool allows also the HTML5 graphics programming of the SDC-xG Graphics Series Sedona controllers.
The applications are developed graphically by linking application objects together. The image below illustrates
the example of the application logic.
The objects that are used to create the application come from application libraries also know as “kits”. From know
on in this document these are called as “kits”. SyxthSense offers wide range of kits for typical application
programming of the controllers.
The Sedona Kits manual describes the details of the kits and how they can used effectively in the applications.
The Sedona Framework allows new kits to be installed through the Workbench software (or through CPT tool if
used). As default the SDC controller come with the factory default kits (application libraries) installed. The
controller uses dynamic memory allocation allowing effective use of the controller memory.
Additional kits (application libraries) can be installed as and when required. E.g. if the application requires
Psychometric Chart functionality this can be added to the system by installing “Energy” kit. The SDC controller
applications can be programmed using basic objects such as mathematical objects, logic objects etc. However
kits such as “syxthHVACFG” include advanced objects such as pumpChangeOver logic and boilerSequencing;
these allow the HVAC application to be produced fast and effectively. The SyxthSense HVAC objects have been
designed for fast application development.

10. Connecting Workbench to SDC-xG Controllers
The Workbench/CPT tool is connected to the controller via a switch (such as SyxthSense SSIES-5P-24V) or
directly from the PC using a cross-over cable. In order to communicate to the controller it is required that both the
PC and SDC-30 are in the same computer network (first three segements of the IP address are the same).
As default the SDC-xG Graphics Series controller IP address is : 192.168.10.11. The default username is Admin.
In order to connect PC (and Workbench), you will need to change the computer IP address through TCP/IP
properties to 192.168.10.x when x is 2..255 but not 11. Set the computer subnet to 255.255.255.0.
To connect the workbench to the controller, in the Workbench select File/Open/Open Sedona(sox). Now enter
the IP address of the SDC controller. Do not change the Port number. The default Username is admin and leave
the Password field <empty>. Click OK to connect to the controller.

12. Resetting the Sedona Application to the Factory Defaults
Sometimes it may be required to load the factory defaults on the SDC-xG controllers (e.g. if the SDC-30
controller application has been accidentally loaded to the SDC-xG g Graphics Series controllers. At the moment,
there are 2 ways to restore the sedona apps for SDC-20G/32G controllers.
“Restore Factory Settings”. function is done with just the by pressing the “Service” button while the controller is
booting up.
A restore to factory settings will do the following ;
1. Restore the IP address to the default which is 192.168.10.11
2. Clear the Sedona application in the Sedona VM back to default (default app is an empty app)
3. A default Sedona apps default login is admin , <no password>. Follow the steps below to restore to factory
settings.
Step 1
Make sure you backup the Sedona apps if you have connection to the SDC-20G/32G.
Step 2
Cycle power and within 5 seconds press and HOLD down the service button until the Error LED starts to flash.
This process will take approximately 10 seconds before the error Led start to blink
Step 3
Cycle the power of the controller again and you will regain connection to the Sedona VM with the default IP
address and also default username and password.
Note :
A SDC-30 sedona apps CANNOT be loaded into the SDC-20G/32G controllers as the sedona apps from a SDC-30 backup is
hardware dependent. Doing so will corrupt the SDC-20G/32G sedona VM and the controller will keep rebooting the sedona VM,
hence the controller is not accessible via Sedona Workbench.
If the rebooting cycle occurs, the status LED will blinks for fast for a few times then light up steady for approx 10 seconds. If the
above note happen, follow the above steps to regain Sedona connection.
