WDAS - Wireless Data Acquisition Systems

Acquire digital and analog data in the field, and
transmit it by radio to the serial RS232 port of a host computer.

Control equipment using digital and analog outputs, by radio,
from the serial RS232 port of a host computer.

Sending analog levels via radio link:  
      analog in ---> radio link ---> analog out
      digital in  ---> radio link ---> digital out

The units with analog or digital I/O can be used in a point-to-point configuration, for example:

•  2 analog inputs on W210A can be transmitted to 2 analog outputs on W510A, via the radio link;
or
•  8 digital inputs from one W310A can be transmitted to 8 digital outputs on another W310A.

This is illustrated in the Application Note (pdf file, 9 pages, opens in new tab or window).

More info on data transmission:

When used for data transfer between two M110A modems, the modems operate
using data packets of up to 70 bytes. Each packet takes approx. 500msec
to be transferred from one modem to the other. The modems will
communicate on RS-232 or RS-485 at various baud rates up to 115kbps,
however they are only designed for sending short data packets back and
forth with gaps of 500msec or more between each packet.

More info on RF communication range - antennas:

In general, we recommend one of 3 types of antenna according to the RF range and communication environment.

Monopole Antenna, gain 1.3 dBi, range 1km at line-of-Sight
Whip Antenna,       gain 3 dBi,  range 2km at line-of-Sight
GP Antenna,          gain 6 dBi,  range 4km at line-of-Sight

The antenna gains are 1.3, 3 and 6dBi respectively, which guarantee 1km, 2km and 4km RF range at Line-of-Sight.
Because environmental conditions vary and often would not be line-of-sight, it is advisable to do a field test before deciding which antenna would be most suitable.
However we can provide guidelines about which antenna to use, based on previous field tests - please contact us with the details
of your application.

Wireless Communication by UHF(400MHz) Band
Most existing industrial wireless devices use microwave frequency (2~5GHz)
Microwave frequency has many limits in industrial field because of straight line and attenuation.
UHF band can achieve long range communication because itis more robust than microwave frequency
