The ADAM-4550 Radio Modem Module from Advantech was successfully used on a seagoing diamond exploration vessel to transmit information from the rotating drill to the onboard control room.
At first, sliprings were considered, but the cost of manufacture and exposure to saltwater spray made it both impractical and unreliable. The solution to the problem proved to be the ADAM-4550 which was housed, with batteries to provide power, in an IP-65 rated enclosure.
The unit operates half duplex with an over-the air data rate of 1 Mbps. The basic modem has 100 mW of output power and has a range of 150 m using a small 'bee-sting' antenna on its rear panel. Ranges in excess of 20 km (line-of-sight) are possible with an external pole-mounted antenna.
The ADAM-4550 radio modem provides reliable wireless connectivity for either point-to-point or to point-to-multipoint networks. It is designed for data acquisition and control applications between remote sensors and the host computer. A typical application might include an ADAM-4550 connected to a host computer via the RS232 interface and a number of ADAM-4550 units at remote sites. Each remote ADAM-4550 can interface with a number of remote devices via an RS-485 network. The ADAM-4550 modules at the remote sites relay the remote data to the host ADAM-4550 and the host ADAM-4550 sends the control commands to the remote sites via radio transmission.
