1 Description
1.1 Introduction
This document describes the integration of BACnet MSTP and BACnet IP installations into ASCII serial (EIA232 or
EIA485) or ASCII IP compatible devices and systems using the Intesis ASCII Server –BACnet Client gateway.
The aim of this integration is to make accessible BACnet system signals and resources from any system capable to be
programmed to read and write simple text messages through EIA232 or EIA485 serial port or Ethernet TCP/IP port (for
example Extron, LiteTouch systems).
The gateway acts as a BACnet IP Client device in its BACnet interface, reading/writing points of other BACnet IP
device(s), and offering this point's values of BACnet device(s) through its ASCII interface using simple ASCII messages.
The readings into the BACnet device(s) performed by the gateway can be by polling or by subscription (COV).
Configuration is carried out using the configuration software IntesisTM MAPS.
This document assumes that the user is familiar with ASCII and BACnet technologies and their technical terms.

1.2 Functionality
From the BACnet system point of view, after the start up process, Intesis subscribes to configured BACnet points or
reads them continuously from their respective BACnet server devices and updates in its memory the value of the
present_value property received from them.
From the ASCII system point of view, after the start up process of the gateway, Intesis waits for any query (ASCII
messages requesting readings of points or ASCII messages requesting writings of points) and acts according to the
message received. See ASCII interface section for details about this ASCII messages.
Each BACnet object from the BACnet server devices is associated to an ASCII, with this, all the configured points of the
BACnet server devices are seen as a single ASCII device with many registers from the ASCII system point of view,
each register corresponding to a present_value of an object on a particular BACnet server device.
When a new value is read from BACnet for a given object/present_value, the new value is updated in the gateway's
memory and made accessible at ASCII Server interface.
In the continuous polling of the BACnet server, if an unresponsive BACnet server device is detected, the corresponding
virtual signal inside Intesis will be activated indicating communication error with the BACnet server device. These virtual
signals indicating communication status in real time with the BACnet devices are also accessible from ASCII, like the
rest of the points of the gateway.

2 BACnet interface
This section describes the BACnet part of the Intesis's configuration and functionality.
2.1 Description
BACnet server devices are represented in the form of Devices holding Objects, normally every physical device
corresponds to a logical one. The Objects can be of different type depending on the data and functionality the represent:
Analog Input, Analog output, Digital Input, etc. Up to 23 different types of objects. Note that Outputs are objects meant
to be written in the direction BACnet network to the device, and the opposite for Inputs (they are meant to offer status
information of the BACnet device). Value objects are bidirectional.
Every Object has different properties. The most meaningful one, and the one used to read and write values by Intesis
is the Present Value property, which indicates the real value of the object. Every Object of the same type in a Device is
identified with its associated Object Instance.
These are the possible BACnet objects supported by Intesis:
Object Type

Every signal is identified with its associated Device + Object Type + Object Instance.
Intesis simulates a virtual BACnet device inside the BACnet system acting as client device in the BACnet system. The
communication with the rest of the BACnet devices is done via the Ethernet port of the gateway which implements the
BACnet protocol.
Intesis implements a single BACnet object of its own: this is, its BACnet Device Object, containing its BACnet Device
Identifier and basic properties of Intesis as BACnet device (name, firmware version, etc).
Using the configuration tool with Intesis it’s possible to scan the BACnet network for available devices and their objects,
which can later be directly added to your configuration. This facilitates the configuration process, avoiding entering them
manually.
BACnet/IP and BACnet MSTP physical layers are supported. Only one physical layer can be used at a time. This is, if
communicating to BACnet using BACnet/IP, BACnet MSTP cannot be used, and viceversa.

2.2 BACnet/IP
Main parameter to set up for BACnet/IP, additional to basic IP settings (IP, netmask, default gateway) is the
communication port. Intesis uses port 47808 (0xBAC0) by default and it can be changed at configuration time.
When using BACnet/IP, device can also act as a Foreign Device (in order to be able to communicate with devices that
are in another network domain), alternatively implement a BBMD itself (Bacnet/IP Broadcast Management Device). This
functionality facilitates communication of devices in other networks with the devices in the network where Intesis is
installed.
Communication with BACnet/IP excludes possibility of communicating with BACnet MSTP from Intesis.
2.3 BACnet MSTP
When choosing BACnet MSTP device needs to be associated with a MAC address (address within the MSTP network
segment), to be configured with configuration software.
Following baud rates are supported for MSTP line: 9600, 19200, 38400, 76800, 115200 or Autobauding (autodetect).
Standard wiring guidelines for EIA485 apply for the BACnet MSTP line.
Communication with BACnet MSTP excludes possibility of communicating with BACnet/IP from Intesis.

2.4 Points definition
Every point defined in Intesis has the following BACnet features associated to it:
Feature
Description
BACnet Device
BACnet device to which belongs the point, from a list of BACnet devices that can be
defined in Intesis (up to 16).
For every BACnet device defined, a virtual signal is created automatically in Intesis to
inform about the communication with the BACnet device, this signal is available also from
the ASCII interface like the rest of points.
BACnet object type
BACnet object type for the point. It can be one of the following BACnet object types
supported by Intesis:
AI = Analog Input.
AO = Analog Output.
AV = Analog Value.
DI = Digital Input.
DO = Digital Output.
DV = Digital Value.
MI = Multistate Input.
MO = Multistate Output.
MV = Multistate Value.
LOOP = Loop
ACCUM = Accumulator
Consult documentation of BACnet device(s) to integrate for information about BACnet object types of the points
desired to integrate.
BACnet object instance
BACnet object instance for the point on the external BACnet device.
Consult documentation of BACnet device(s) to integrate for information about BACnet object instance of the
points desired to integrate.
Note that configuration tool used with Intesis enables for discovery of existing BACnet devices in the network, as well
as their BACnet objects and types, which can be later directly added in configuration. This facilitates the process of
choosing suitable parameters above for every BACnet object on every BACnet device to integrate.

3 ASCII interface
This section describes the ASCII interface of the Intesis, its configuration and functionality.
3.1 Description
The gateway can be connected to any ASCII enabled device using its EIA232 interface (DB9 connector DTE), EIA485
interface or TCP/IP (Ethernet connector) and offers through this interface the possibility of supervision and control of its
internal BACnet points using simple ASCII messages.
On receiving messages corresponding to write commands in its ASCII interface, the gateway sends the corresponding
write command message to the associated BACnet device.
When a new value for a point is received from BACnet, the corresponding ASCII message indicating the new value will
be sent through the ASCII interface, but only if the point is configured for sending this "spontaneous messages", if it is
not configured to do so, then the new value will be available to be polled in any moment from the ASCII enabled device
connected to this ASCII interface. This behaviour of sending or not through the ASCII interface the new values received
from BACnet is configurable individually per point in the gateway.
3.2 ASCII Serial
Serial communication for the ASCII communication can be configured to match the ASCII master device.
Only the RX, TX and GND lines of the EIA232 connector are used (TX/RX+ and TX/RX- for EIA485).
3.3 ASCII TCP
The TCP port to use can be configured (by default 5000 is used).
The IP address, subnet mask and default router address to use by Intesis can be also configured.
3.4 Address Map
The ASCII address map is fully configurable; any point in the Intesis can be freely configured with the desired internal
register address. Check the configuration tool manual for more information.
3.5 Points definition
Every point defined in the gateway has the following ASCII features associated to it, which can be configured:
Feature

4 Connections
Find below information regarding the Intesis connections available.
Power Supply
Must use NEC Class 2 or Limited Power Source (LPS) and SELV rated
power supply.
If using DC power supply:
Respect polarity applied of terminals (+) and (-). Be sure the voltage
applied is within the range admitted (check table below). The power
supply can be connected to earth but only through the negative terminal,
never through the positive terminal.
If using AC power supply:
Make sure the voltage applied is of the value admitted (24 Vac). Do not
connect any of the terminals of the AC power supply to earth, and make
sure the same power supply is not supplying any other device.
Ethernet / BACnet IP / ASCII TCP/IP
Connect the cable coming from the IP network to the connector ETH of
the gateway. Use an Ethernet CAT5 cable. If communicating through the
LAN of the building, contact the network administrator and make sure
traffic on the port used is allowed through all the LAN path (check the
gateway user manual for more information). Default IP is
192.168.100.246. DHCP is enabled by default.
PortA / BACnet MSTP
Connect the EIA485 bus to connectors A3 (A-), A4 (B+) and A1 or A2 (SNGD) of gateway’s PortA. Respect the polarity.
PortB / ASCII Serial
Connect the EIA485 bus to connectors B1 (B+), B2 (A-) and B3 (SNGD) of gateway’s PortB. Respect the polarity.
Connect the serial cable EIA232 coming from the external serial device to the EIA232 connector of gateway’s PortB.
This is a DB9 male (DTE) connector in which only the lines TX, RX and GND are used. Respect the maximum distance
of 15 meters.
Note for PortA and PortB; Remember the characteristics of the standard EIA485 bus: maximum distance of 1200
meters, maximum 32 devices connected to the bus, and in each end of the bus it must be a termination resistor of 120
Ω. The port includes a DIP-Switch for configuration of biasing circuit as well as termination:
SW1: ON: 120 Ω termination active
OFF: 120 Ω termination inactive (default)
SW2-3:
ON: Polarization active (default in BACnet MSTP port)
OFF: Polarization inactive (default in ASCII serial port)
If the gateway is installed in one bus end make sure that termination is active.
Console Port
Connect a mini-type B USB cable from your computer to the gateway to allow communication between the Configuration
Software and the gateway. Remember that Ethernet connection is also allowed. Check the user manual for more
information.
USB
Connect a USB storage device (not a HDD) if required. Check the user manual for more information.
Ensure proper space for all connectors when mounted (see section 7).

4.1 Powering the device
A power supply working with any of the voltage range allowed is needed (check section 6). Once connected the RUN
led (Figure above) will turn on.
WARNING! In order to avoid earth loops that can damage the gateway and/or any other equipment connected to it, we
strongly recommend:
•The use of DC power supplies, floating or with the negative terminal connected to earth. Never use a DC
power supply with the positive terminal connected to earth.
•The use of AC power supplies only if they are floating and not powering any other device.
4.2 Connection to ASCII
4.2.1 ASCII TCP/IP
Connect the communication cable coming from the network hub or switch to the ETH port of Intesis. The cable to be
used shall be a straight Ethernet UTP/FTP CAT5 cable.
4.2.2 ASCII Serial
Connect the communication cable coming from the ASCII network to the port marked as Port B of Intesis. Connect the
EIA485 bus to connectors to connectors B1 (B+), B2 (A-) and B3 (SNGD) of gateway’s PortB. Respect the polarity.
Remember the characteristics of the standard EIA485 bus: maximum distance of 1200 meters, maximum 32 devices
connected to the bus, and in each end of the bus it must be a termination resistor of 120 Ω. Set port switch SW1 to ON
if gateway is installed on one bus end. SW2-3 will generally go OFF (no polarization), as polarization will typically be
provided in the ASCII Serial master device.
4.3 Connection to BACnet
4.3.1 BACnet IP
Connect the communication cable coming from the network hub or switch to the ETH port (Figure above) of Intesis. The
cable to be used shall be a straight Ethernet UTP/FTP CAT5 cable
In case there is no response from the BACnet devices to the frames sent by Intesis, check that they are operative and
reachable from the network connection used by Intesis. Check the Intesis Ethernet interface sending Pings to its IP
address using a PC connected to the same Ethernet network.
Check as well with the network admin that there are no limitations regarding UDP communication or ports blocked.

Configuration for BACnet client has three sections: General Configuration, Devices Configuration and Gateway Mode.
•General Configuration
In this section, following parameters should be configured:
1. Device Name. Name of the device in the bacnet network (‘object name’ property of device object)
2. Device Instance. Instance number of the device in the bacnet network (instance number property of device
object)
3. Password. BACnet password of the device to execute service ‘Device Management – Restart’, sent by other
device in the BACnet network.
4. Sequential comms. Enables sequential communication with other BACnet server devices. This is, no new
request will be initiated from Intesis until response to last request has been received. This becomes necessary
in case of communication with BACnet MSTP devices behind a BACnet IP to MSTP router, as no concurrent
transactions are possible in MSTP.
•Gateway Mode
In this section, following parameters should be configured:
1. Mode. Select whether Intesis is going to connect with BACnet IP or BACnet MSTP. Rest of parameters in the
section will be different depending on this.
2. (Mode IP) UDP Port. UDP port that will be used for BACnet IP communication. It defaults to 47808 (0xBAC0)
3. (Mode IP) Network Role. Related to capability of the device of communicating with devices from other
networks. Disabled, Foreign Device or BBMD are the possible choices. In case of Foreign Device, IP of the
BBMD where it will connect needs to be entered, as well as TTL (time-to-live). In case of selecting BBMD, table
of BBMD’s in the BACnet network needs to be entered.
4. (Mode MSTP) Max Masters. Highest MAC address of BACnet MSTP master device in the MSTP line.
5. (Mode MSTP) Max Info Frames. Max number of frames that the device can send out to the network when it
receives token in the MSTP line.
6. (Mode MSTP) Baudrate. Baudrate of the BACnet MSTP link.
7. (Mode MSTP) MAC Address. MAC address of Intesis as BACnet MSTP device in the MSTP line.
•Devices Configuration
In this section, a single entry for which BACnet server device the Intesis is to communicate with needs to be entered.
In Signals table, each signal will need to be associated with the device it will be read to/written from.

Devices can be added in three ways:
•Manually: With checkbox ‘Use template’ disabled, Add button should be clicked. Number of devices to add can
be adjusted in the text field next to button Add.
•From template: Same as manual but based on a template file. This will add in Signals table all the signals
specified in the template file for the device to be integrated.
•From scan: Gives functionality to scan the BACnet network for existing BACnet server devices and their
objects, enabling to add them in the config. See section ‘BACnet scan functionality’ below for further detail.
Once a device is added, following fields must be filled in for each device:
Figure 5.6 Devices configuration section
1. Device Name. Device identifier within MAPS. It will be used to reference the device from the signals table
2. Recipient Type. Way in which the device will be identified within the BACnet network. Options are Device
(instance), Address, Address (MSTP). Depending on which option is chosen different parameters will appear to
enter the details of the address.
3. (Recipient type: Device) Object Instance: Instance number of device object for the BACnet server device.
4. (Recipient type: Address) Network: Destination network, 0..65535. 0 for local network, 65535 for broadcast
(all networks).
5. (Recipient type: Address) IP / Port: IP and Port of the BACnet server device.
6. (Recipient type: Address (MAC)) Network: Destination network, 0..65535. 0 for local network, 65535 for
broadcast (all networks).
7. (Recipient type: Address (MAC)) MSTP MAC Address: MAC address 0..255 of the BACnet server device.
8. Reading type: Related to service that will be used to read the BACnet server device. Options are Polling
(ReadProperty), COV, COV-unconf (unconfirmed COV), Polling Multiple (ReadPropertyMultiple).
9. Write priority: priority with which writes will be performed. Default is (none) (no priority), can be chosen from 1
(highest) to 16 (lowest) and none.
10. COV Lifetime: Periodic timeout at which COV subscription will be renewed.
