Evaluation kit for 868MHz Radio Modem (RCQ5-868-EV)
This Evaluation kits is composed from:
- N.2 Evaluation board
- N.2 868MHz Antenna
- N. 2 USB Cable
- Radio Modem with AT Command (Transparent Transmission Protocol)
The RF modem is very simple to use and provides a wireless RS232 link with a RF data rate of up to 200kbps (2-GFSK modulation).
The module can work also in Long Range Mode (LRM) with a RF data rate egual to 2.5kbps.
The transceivers has the functions of a complete radio modem and simply require CMOS/TTL data at the transmit input and the corresponding transceiver(s) output
the same data. Preamble and CRC are automatically generated and added to the RF transmission.
- Over The Air Command (OTA Command)
The module has the ability to manage No. 4 digital outputs and No. 4 digital inputs both locally and remotely (OTA Command) by sending simple AT commands.
- ALARM Functionality
With this function, when a digital input change status (DEVICE A) a message will be transmitted via UART to the DEVICE B : “Alarm_0_1
- Remote I/O Functionality
This is two-way transmission used in the field automatic control. It is possible Turn ON and turn OFF the remote IO mirroring function.
When we enable the Remote I/O function, if any Digital Input is change on the Station A, the digital output of the remote Station B will also mirror these states at the same time.
