ELPRO 405U
 |
The 405U has been designed to be easy to use and simple to install. It uses a low power UHF radio which does not require a radio licence*. The module is fully integrated with radio, power supply, serial ports and microprocessor controller housed in a strong industrial aluminium case.
Simple and Reliable
The 405U includes a radio transceiver, allowing communications in both directions, so the modules can check and control the transfer of information.
The 405U is suitable for both simple and complex systems. It can operate in a transparent mode, where the host devices provide error checking and communications control. For less intelligent host devices, the 405U can provide the addressing, error checking and control of communications. The 405U can also accept Hayes compatible commands for selective addressing.
High Speed Wireless Data
Host devices can connect to the 405U via RS232 or RS485 serial ports, at data rates up to 38.4Kb. The 405U has two internal buffers of 8Kbytes and the radio can transmit data packages configurable up to 520 bytes, at speeds configurable up to 9600 bits/sec. The 405U radio modem is both low cost and very flexible.
