1. General
1.1 Introduction
The Basalte Serial.link is a control interface to connect Basalte RS485 keypads and Auro motion
sensors with a home automation processor. The Serial.link supports a total of 6 x RS485 lines with
a maximum of 32 devices per line.
The Serial.link integrates Basalte keypads and motion sensors with a home automation processor
by means of a TCP/IP connection or an RS232 connection. The central processor can be, Lutron®,
...
Lutron®Homeworks QS
The Serial.link enables the integration of Basalte keypads and motion sensors with a Lutron®
HomeWorks QS®system.
In this configuration, the Serial.link (master) will establish the communication with Lutron®
processor and will also control the Sentido keypads and Auro motion sensors. The Serial.link
configuration tool allows you to commission the keypads and motion sensors, and integrate them
into the HomeWorks QS®software by the use of Integration ID’s.
This manual provides a general overview of the Serial.link. The integration with Lutron®Homework
QS®is described in a dedicated application note which can be found on the Basalte Support
website (Serial.link_AN_Lutron_x.y).

1.2 Topology
The Basalte Serial.link is able to control up to 192 Sentido or Auro devices distributed over 6
RS485 lines. Each line can contain up to maximum 32 devices and must be wired according a linear
bus topology without any branches. This means that each line has exactly two endpoints: the
Basalte Serial.link and one Sentido keypad or Auro motion sensor. On every last Sentido keypad
(endpoint), the TER switch should be placed in the ON position (termination enabled).
The bus cable to connect the keypads and motion sensors consists of four strands: two strands are
used for power and two strands are used for data (which need to be a shielded pair). For example:
shielded twisted pair (STP).Lutron®bus cable is a suitable RS485 bus cables.
The Serial.link requires a power supply between 10 and 30V DC. A power supply of 24V DC is
recommended.
Power consumption Serial.link: 10W
Power consumption Sentido keypad: 1W
Power consumption Auro motion sensor: 0.5W
Used cable : Cable with four strands of which 2 are shielded (data pair)
Max. cable length : 1,2 km (4000 feet)
Max. keypads per line : 32
TER : Switched “On” at every last keypad of a line (endpoint).

1.3 Sentido Keypads
Description
Sentido RS485 is a touch-sensitive keypad compatible with all Sentido and Enzo covers, either two-
way or four-way. Each separate touch sensitive surface of Sentido can control various functions,
using both short and long press.
By touching more than one surface at the same time, additional comfort functions can be
activated. (this is called the ‘multi-touch’)
The multicolor LED backlight provides status feedback and can be used as nightlight. Sentido has a
built-in temperature sensor as well which can be integrated in certain home automation systems.
Sentido RS485 - installation
General guidelines for installation are described in the ‘Sentido RS485 installation manual’.
Important remarks concerning installation:
•On all devices the TER switch should be switched “off” (termination disabled), except on
the last device per line (endpoint) the TER switch should be “on”.
•Configure the RS485 address with the two rotary dials. Please note that the address is in
hexadecimal notation.

1.4 Auro Motion sensors
Description
Auro RS485 is a miniature motion sensor which, when mounted in the ceiling, completely blends
into the environment due to its innovative flat design.
Only requiring an opening of 1.7”, it is very easy to install.
Auro has a built-in light sensor to use for light dependent switching, dimming and controlling
scenes.
The internal temperature sensor discretely reports the room temperature to the home automation
system, while it can also be used to trigger a heat alarm in case of an abnormal temperature rise.
With a vertical detection angle of 90° it has a detection area with a diameter of 16 ft when installed
at a height of 8 ft, making it perfect for hallways, toilets and small rooms.
The white internal LED provides feedback of detected motion and can be manually controlled.
Auro RS485 - installation
General guidelines for installation are described in the ‘Auro RS485 installation manual’.
Important remarks concerning installation:
•Configure the RS485 address prior to installing the sensor into the ceiling. The assigning
and testing of Auro addresses can be done using the Serial.link configuration tool (see
separate application note for Lutron®). Please note that the address is in hexadecimal
notation.

1.5 Serial.link –hardware overview
Dimensions
The Serial.link is a 9-DIN rail module (158mm or 6 7/32 inches wide), 90mm high and 58mm
deep.
Status LED (1)
The central LED will report the status of the Serial.link:
•White: normal operating mode, actual status depends on central processor used :
oLutron®: the Serial.link has established a connection with the Lutron®processor.
•Blue: Configuration loaded, no connection active with Lutron® processor.
•Blue blinking: no configuration loaded in the Serial.link.
•Red: firmware upgrade of Serial.link ongoing (no commands can be send to the module).
•Yellow: reboot of Serial.link initiated.
•Yellow blinking: wrong telnet login used.
Reset button (2)
The reset button can be used to either reboot or reset Ethernet settings:
•Pressing 3 –7 seconds will reboot the Serial.link, the status LED will blink yellow once.
•Pressing 7-10 seconds (LED turns green) will reset the Ethernet configuration of the
Serial.link to default, the status LED will blink yellow once.
Data feedback LED (3)
The data feedback LED is located next to each data connector. When data is transmitted over a
specific data-line, the LED will light up green.

USB connector (4)
The USB connector is only used for service purposes. This port can’t be used to program the
device.
Ethernet connector (5)
The Serial.link has two Ethernet ports with integrated Ethernet switch to daisy chain to other
devices. Both ports have equal importance.
RS232 connector (6)
Can be used to connect to a home automation system by serial RS232 connection.
2. Communication settings
The Serial.link can communicate with the home automation processor using RS232 or TCP/IP. The
settings of both protocols are described below.
2.1 RS232
-baud rate : 38400
-data bits : 8
-stop bits : 1
-parity : No
The DB9 connector of the processor must be as follow:
TX
Pin 3
RX
Pin 2
Ground
Pin 5
Note: The ground of the Serial.link must be connected with the ground of the home automation
processor.
When using a processor as master device and the serial hub as a slave, the RX from the master is
the TX from the slave. So the TX from the master is the RX from the slave.

2.2 Ethernet
The Serial.link will obtain an IP address automatically through DHCP. If the DHCP server can’t
provide an IP or is unavailable, the Serial.link will be on a fixed IP address after a delay of 20
seconds (192.168.2.241).
The Serial.link configuration tool allows you to discover Serial.links on the local network and
change the IP configuration.
When integrated with Lutron®system, Serial.link will connect with Lutron®HomeWorks QS®. The
configuration of Lutron®HomeWorks QS®and keypads is done using the Serial.link configuration
tool. See also the Serial.link –Lutron®application note providing more information on the
integration of Serial.link with Lutron®HomeWorks QS®.
2.2.1 Serial.link network settings
The Serial.link configuration tool allows you to discover any Serial.link on the local network and
change its IP configuration.
Discover
Launch the Serial.link Configuration tool and select the General tab. By clicking the Discover
button, every Serial.link module in the local network can be discovered.
