The ATC-873 is an inexpensive, highly integrated serial radiomodem useful for short-distance (1 km) data transmission, using the ISM 868MHz free band.
Due to its small size and weight, low power consumption and high stability and reliability, it can be conveniently used in wireless meter reading systems, parking meters, people-presence meters, alarm systems, data collection systems, industrial remote controls, etc..
The ATC-873 adopts a half duplex communication channel more suitable for point-to-multipoint communication mode.
The transmission channel realized with the ATC-873 is transparent to the user.
Advantages of 868 MHz radio transmission
The 868MHz frequency band in Europe, represents an excellent compromise between range and small footprint.
- In the open field and with a ¼-wave antenna, ranges of nearly 1km can be achieved
- Allows the crossing of concrete walls
- Transmission is little disturbed by obstacles (unlike Wifi or Bluetooth at 2.4 GHz)
- The risk of interference is very low (this frequency is reserved for certain applications and the power of the devices is limited).
The product is supplied complete with the following accessories:
- AC/DC power adapter
- 868MHz 2.5dBi SMA-M 90° antenna (ANT-03)
- RS-232 cross cable
- CD Rom documentation and drivers
An adapter is optionally available to allow DIN rail mounting.
