2.2. DESCRIPTION
The
ADA-I911W
USB to 1-WIRE converter allows connection of several 1-WIRE's interface systems such as: temperature
measurement systems, real time clocks, EPROM memory, A/C transducers etc., to common 1-WIRE bus. The transition from 1-WIRE
interface to USB interface in ADA-I911W provides controller 1-Wire bus and the USB controller. In this way, the user does not need to
delve into the quite complicated protocol 1-WIRE. The converter allows monitoring and/or controlling of 1-WIRE circuits via USB
interface of computer PC-class, equipped with suitable software. CEL-MAR company provides an example of software for the
visualization of temperature measurement called Lämpömittari taken by Timo Sara-aho. The software supports circuits for measuring
the temperature eg. DS18S20. In the configuration settings of
Lämpömittari
software, in section
MicroLAN
should be used the
DS9097U
adapter.
ADA-I911W is equipped with a female USB socket B-type for connection of USB interface and the screw terminal block for twisted-pair
connections of 1-WIRE interface. The converter is powered from USB port. Together with the converter we supply drivers for Windows
98, ME, NT, 2000, XP, 2003, Vista, 7, 2008. Installing this software on Operating System it add the additional COM port about the next
free number, witch can be used as standard COM port. It is virtual COM port therefore some software use DOS can work improperly.
2.3. APPLICATION
ADA-I911W converter can be use in the all types of local systems, based on
MicroLAN
networks such as: access control, control the
operation of air conditioning and heating, a remote control and monitoring of alarm systems, fire extinguishers, etc.
One of the fastest growing markets today is the market of alarm systems, in which MicroLAN is used for connection the sensors with
alarm control panel, where instead of few or several wires can only use 3. MicroLAN in such use prevents the possibility of "defraud"
alarm system by shorting or cutting the line and at the same time provides ease of automatic configuration and reconfiguration of the
alarm system during operation. Much easier than the standard versions, is also keeping test procedures that help eliminate faulty
system components.
2.4. EPROM MEMORY PROGRAMMING
The version 2-x of ADA-I911W converter allows to programming the EPROM memory. This is done with the switch MODE side of the
housing, in position “PROG”, connecting programmable circuit to the bus and making the programming. If there are circuits to the bus
on which do not require programming, the switch should be set in position “NORM”.
2.5. 1-WIRE CIRCUITS COMMUNICATION
For communication with 1-WIRE circuits can be used the software as follow:
a/ OneWire Viewer available here

,
b/ LogTemp available here

,
e/ or other, cooperate with DS9097U adapter.
2.6. COMMUNICATION VIA VIRTUAL COM PORT
The communication between ADA-I911W converter and the application is via the virtual COM port, with baud rate 9600bps (the baud
rate set in ADA-I911W after powering) or others, setted by the software of master device (eg. PC) ie.: 19200 bp/s, 57600 bp/s, 115200
bp/s.
