SST-2450 is a spread spectrum radio modem with controlling an RS-232/RS-485 interface port. It is designed for data acquisition and control applications between a host and remote sensors. It is also useful for those applications where the installation of cable wire is inconvenient. The SST-2450 can be used not only in peer-to-peer mode, but also in a multi-point structure .

The SST-2450 is based on a direct sequence spread spectrum and RF technology, operating In the ISM bands with a Frequency Range of 2410.496MHz~2471.936MHz. The Channel Spacing is 4.096MHz.

The SST-2450 is similar to the SST-2400, with the major difference being the setting control method. The SST-2400 is set using jumpers, whereas the SST-2450 is set using a software utility. The older SST-2400 can work in conjunction with the new SST-2450 by changing its internal 8051 chip. The new chip includes updated firmware, so please contact us and we will send a new chip. Refer to page 26 for detail.

The applications of 802.11b wireless LAN are getting more and more popular by the more and more mature technology. It's not only faster than the industrial traditional transmission i.e. RS-232, RS-485, RS-422 etc, but also able to decrease the troublesomely wiring works. It's also more mobility than Ethernet network.

In order to reduce wire-placement tasks and conveniently manage data acquisition modules, ICPDAS provide a range of RF I/O modules to meet the above requirements.

The hardware structure is based on the ICPDAS I-87K series module and the software supports the ICPDAS DCON protocol, making it easy to integrate into any system.

There are three RF I/O series modules available for selection: RF-87K1, RF-87K2, RF-87K5 and RF-87K9. The last character of the model number denotes the number of slots.

The unique specifications of the RF I/O series modules means that it supports the ICPDAS I-87K series I/O modules, meaning that the old I-87K back end need only be changed to an RF I/O module and the system can be updated to a wireless network.

The RF-87K series is based on a direct sequence spread spectrum and RF technology, operating in the ISM bands with a Frequency Range of 2410.496MHz~2471.936MHz, with a Channel Spacing of 4.096MHz.

By changing the default antenna to a high gain antenna, the transmission range of the RF-87K series can be extended. In addition, the unique specifications of the RF-87K series allows the channel to be changed using a simple switch, meaning that most configuration problems can be easily solved when adding a new module. It is also easy to add an RF-87K series module to your existing SST-2400/2450 network.

Note that when ordering an RF-87K series module, I/O modules are not included and must be purchased separately. The RF-87K series also needs to operate with any device that is connected to the SST-2450.
