Radius PDM-Radius PDM

Sipariş No : Radius PDM

The Radius PDM is an 19" rack mounted version of PDR 121 and 221 modem with advanced VHF/UHF digital radio capabilities designed for wide area remote monitoring and control applications, encompassing point to multi-point communication with peer-to-peer compatibility. The PDM is available in either a transparent or a protocol decoding version with standard or high power options available.

The Radius PDM is an 19" rack mounted version of PDR 121 and 221 modem with advanced VHF/UHF digital radio capabilities designed for wide area remote monitoring and control applications, encompassing point to multi-point communication with peer-to-peer compatibility.  The PDM is available in either a transparent or a protocol decoding version with standard or high power options available.
The data radio offers up to 19.2kbps over-the-air data rate and is designed for both point-to-multipoint  and point-to-point networks in the VHF and UHF bands.
The PDM Wireless Base Station gives large area communication coverage. The PDM can achieve distances of up to 50km at VHF and 30km at UHF.  With unique message routing, a PDM network can cover covering several 1,000km2.

The PDM supports two serial ports and one Ethernet port, allowing a variety of equipment to be connected to it. It is also possible to mix connections in the system, so that the Master site could run IP and the slave sites either IP or RS232.

The PDM data radio supports event triggered communication and has built-in collision management to maximize network throughput. The data radio provides 128-bit encryption and FEC (Forward Error Correction) with inter-leaving that can recover even severely corrupted data messages. Receiver sensitivity is very high allowing exceptional recovery of signals.
