The ELPRO 805U radio modem provides RS232 or RS485
· On-line "dial-up" control using AT commands
connections by radio. It is a low cost wireless alternative
· Repeater functionality in all units
for linking PLC's, data loggers, supervisory computers and
· Repeater routing via address selection
intelligent transducers.
· Security against cross-talk between systems
The 805U has been designed to be easy to use and simple to install. It uses a low power 868MHz radio which does not require a radio licence in most European countries. The module is fully integrated with radio, power supply, serial ports and microprocessor controller housed in a strong industrial aluminium case.
