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.
SC-IRDA Infra-red Communications Interface 2.4 Datalogger Communication Modes Baud rate (default): 9600 Manually selectable baud rates: 1200, 9600, 19200. Baud rate is automatically set to 19200 baud for datalogger operating system upgrades. SC-IRDA is compatible with 21X, CR7X, CR500, CR510, CR10, CR10X, CR23X and CR5000 dataloggers.
SC-IRDA Infra-red Communications Interface IRDA Sensor fitted to enclosure using a high-quality cable gland (cord grip). FIGURE 1. SC-IRDA Sensor Installed in a Standard Enclosure If mounting the SC-IRDA in this way, you need to consider several factors to ensure ideal placement of the interface. The final installation position needs to allow you to hold your computer in an acceptable position such that you can use it comfortably whilst pointing it at the sensor at the end of the SC-IRDA interface.
SC-IRDA Infra-red Communications Interface end, but care must be taken to ensure that the 9 way D connector is sealed if exposed to the elements. Contact Campbell Scientific if you require a special assembly. The interface is rated for exposure to temperatures ranging between -25 to +50°C as standard. It will survive many years of use with normal rates of temperature change.
SC-IRDA Infra-red Communications Interface 4. Operating Instructions NOTE Whichever computer system or software package is used (see below) in all cases the IRDA port on the computer needs to be aligned with the sensor on the SC-IRDA for at least 5 to 10 seconds before attempting to communicate with the datalogger. This is to allow time for the two IRDA devices to recognize each other and to negotiate a working IR link.
SC-IRDA Infra-red Communications Interface 4.2.1 PC200W Version 1.2 and PC208W Version 3 (or later) Both of these programs will work with the SC-IRDA on all but the slowest PCs. PC200W only supports COM 1 to COM 4, and so you must ensure the virtual IRDA serial port maps to one of these numbered ports. PC208W does not have this limitation. Both of these programs will generate a warning message in the low level log files when the serial port is first opened. This can be ignored. NOTE PC200W version 2.
SC-IRDA Infra-red Communications Interface data collection for dataloggers that support speeds higher than 9600 baud such as the CR23X and CR5000 dataloggers. To use these speeds a simple ASCII string needs to be sent to the SC-IRDA before any communication is attempted with the datalogger. These strings and their function are shown in the table below.
