Product Name Type Connectivity Product Description
ModemModbus TCP/IPGrayhill offers the EZCom-IP family of wireless Industrial Radios. EZCom-IP is sold two ways, depending upon the application. In simple point-to-point applications, the EZCom Bridge is a pre-configured radio, which acts as a wire replacer when wiring is uneconomical or impossible. The EZCom-IP Router is intended for more complex point-to-multipoint or multiple-access networking. More sophisticated IP address configuration is accomplished using EZCom-IP Explorer. EZCom's network controller packetizes the data prior to transmission, which provides communication handshaking, error detection, packet sequencing, and supports up to 128 route entries to extend the communication range. For error detection, EZCom uses a Cyclic Redundancy Check (CRC) with automatic packet retransmit. The EZCom-IP radio is based on spread spectrum technology with direct sequence spreading for enhanced interference immunity, reliability, and extended range. Additional reliability is provided through built-in, out-of-band filtering. Multiple Access Networking is achieved through the use of Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) shared media etiquette. The transceiver can be programmed to use different RF channels and different PN codes allowing collocated networks to operate independently. EZCom's data port is a standard 10BaseT-Ethernet interface.
