RS-232/485 Converter
CON-768 (Rev 3.3)
Document Edition 1.4
Product Description
The Delta Controls RS-232/485 Converter converts RS-
232 signals to/from RS-485 signals. It connects to Delta
Controllers through a service tool port using a RJ11 quick
connect cable. The Service Tool Port is built onto many
of Delta’s ORCA controllers, including the BACstat II
(DNS-24/DNT-Txxx) and most of the Application
Controllers.
The Delta Controls RS-232/485 Converter allows Service
Personnel or Building Operators to connect directly to
any BACnet MS/TP network through their PC or
Laptop’s RS-232 Serial Port. Once connected they have
access to the entire network of controllers. The converter
can also be used when flash loading Delta’s BACnet
MSTP controllers to a new version of firmware.

Important Information
The RS-232/485 Converter can be used with any BACnet MS/TP network.
NOTE:While the CON-768 can be used on any BACnet MS/TP network it is designed to connect
through a Delta proprietary RJ11 service port connection. This means that in order to connect a
CON-768 to a BACnet MS/TP network requires at least one Delta controller with a service port, or
an RTS-20J sensor. (The RTS-20J is a wall thermistor that has had a service port added to it’s
enclosure with termination points to attach it to the MS/TP daisy chain and 24Vac to power the
converter.)

Indicators
LED Function Description
POWER/
STATUS
Indicates that the RS-485/232
Network Converter (CON-768) has
power applied.
This green LED is on steady for normal operation
and blinks during auto configuration.
Tx
(RS-485)
Indicates that the RS-485 port is
broadcasting on the RS-485 network.
This green LED will blink quickly in a regular
repeating pattern.
Rx
(RS-485)
Indicates that the RS-485 port has
received information from a
controller on the RS-485 network.
This red LED will blink quickly in the same
regular repeating pattern as the Tx LED provided
all controllers are communicating. The blinking of
the Rx LED will lag slightly behind the blinking of
the Tx LED.
Mounting
The RS-232 (9-pin connector) port on the CON-768 plugs directly into the PC 9-pin serial port. The RS-485
(RJ11) port plugs directly into the RJ11 connector of the Service Tool Port on the ORCA controller.
Power
The CON-768 is powered by24Vac supplied through the service tool port of the Delta controller it is connected
to.
Communications Setup
ORCAview Login through the Service Port
NOTE:In order to use the new converter with ORCAview on a 3.22 site you require 3.22a OWS
Build 556 (or newer) and on a 3.30 site you require 3.30 OWS Build 1063 (or newer). In these
builds of OWS the V2 Micronet protocol is no longer supported so you cannot use the CON-768 to
login to a V2 Micronet Network of controllers.
Run ORCAview and when the login dialog is displayed on the screen enter your Username and Password, then
click on the Advanced tab. Ensure the connection method is properly configured by verifying these settings:
• CONNECT USING: Serial (BACnet MS/TP)
• COM PORT: COM1 (or whichever port the converter is connected to)
• BAUD RATE: Set the Baud Rate to match the network speed the device with the Service Port jack is
communicating at on its network. LINKnet networks should be set to 76800 bps, and MS/TP
networks default to 76800 bps (but could be set to something else as required).
• ADDRESS: The address field on the MS/TP login dialog is the MS/TP Mac address that the CON-
768/OWS will use to identify itself on the network. This number defaults to 127 and typically will not
need to be changed. It must be a value between 1-127 and unique on the MS/TP network segment the
converter is connected to. Since Delta typically only uses Mac address ranges 1-99 for panel
addresses using the 100-127 range for the OWS/converter will help reduce the possibility of creating
duplicate network addresses for a site.

Once you have verified the connection settings, click on OK to login and begin communicating freely as
configured and as defined by your System User Access (SUA) object settings. Devices should begin to show
up in the Navigator network tree and you should have system-wide access to all BACnet devices and their
objects across the network.
NOTE:If you have some of the earlier version 3.22 controllers they may not accept 127 as a valid
MAC address. This is because on earlier versions the address ranges were limited as follows:
• For controllers configured to reside on a MS/TP network segment the valid address range
was set from 1-99.
• For controllers configured to reside on a Linknet network segment the valid address range
was set from 1-13.
For more detailed information on the logging into panels through the service tool port refer to Appendix H of
the ORCAview Technical Reference manual.
Flashing a Panel Using the CON-768
Flash upgrading a panel’s firmware using a CON-768 requires a PC with 3.30 Version of Delta Flashloader
(Build 1063 or higher).
NOTE:Only the Toshiba based DSC/DAC products can be flash upgraded using the CON-768
over RS-485. The DCU must still be flashed using a serial cable over RS-232.
Preparing to Run Flash Loader
1. Ensure that the panel database is backed up.
2. Place the controller into loader mode by powering off the controller then turning all of its address dip
switches to the on position and powering it back up.
3. Use a CON-768 and RJ11 cable to connect the PC COM port to the service port on the controller.
(The controller should not be connected to any other controllers over the NET 1 MS/TP port while
being flashed in loader mode.)
Running the Flash Loader
• Click on the Windows Start button and select Program\Delta Controls\ORCAview Flash Loader or
click on the ORCAview Flash Loader icon on the desktop.
Selecting an Upgrade File
• In the Filename dropdown list, select the required file. The Upgrade File Details field shows the
details of the selected upgrade file. For a DAC look for a filename similar to: DAC V3 322
Bxxxxx.fls.
Changing the Connection Settings
1. Click the Settings button.
2. On the Setting dialog, set the Protocol to Micronet RS-485 (DAC25x)
3. From the Port drop-down list, select the PC COM Port that the converter is connected to.
4. Click OK. The settings are saved and the dialog closes.

Transmitting the Upgrade File
1. Click the Query button to confirm communications with the controller and determine the current
firmware in the device.
2. Click the Program button. (Depending the version you are upgrading to/from a flash lock with
sufficient upgrade counts may be required before Flashloader will allow you to upgrade the panel.)
3. The Flash Loader transmits the new firmware. The Status and Progress fields indicate the current
upgrade operation. Once the upgrade is complete the Status field will show Upgrade Completed.
For more detailed information on the Delta Flash Loader refer to the Flash Loader Users Guide.
