SC-IRDA Infra-red Communications Interface

1. Introduction

The SC-IRDA interface is designed to provide a wireless connection between a hand-held computer and a datalogger. It is designed to be permanently installed through the wall of environmentally sealed enclosures thereby removing the need to open the enclosure or expose any connectors whilst allowing full communication with the datalogger inside.

The quiescent power consumption of the SC-IRDA is very low so it has no significant effect on the overall power consumption of the logging system.

The SC-IRDA also supports a new mode of communicating with some dataloggers (the CR510, CR10X and CR23X with new standard operating systems) that allows it to be connected at the same time as other modem devices, for example a telephone modem, thus avoiding the need for any extra port switching device.
