UHF radio communication link The Communication Interface houses the appropriate hardware for the desired communication link for RS 485 and UHF radio communication packages 2 3 2 RS 232 Communications The cabling for RS 232 communication consists of a Y cable and a standard CATSe patch cord not provided The female 9 pin serial connector should be connected to COMI on the back of the CDP The male 9 pin serial connector should be connected to the female connector of the cable going to the Peripheral Interface This allows the AWOS Net to listen to the CDP output and still keep the connection to the Peripheral Interface The standard CATSe patch cord can then be connected to the RJ 45 jack at the end of the Y cable 2 3 3 RS 485 Communications An RS485 to RS232 converter is mounted in the Communication Interface and pre wired at the factory The CATSe connection cable should already be mounted into the Peripheral Interface if the AWOS Net is purchased with the system If the AWOS Net is added later this cable will be provided as part of the AWOS Net and will need to be installed into the Peripheral Interface using the following steps 1 Remove the cover from the Peripheral Interface to expose the PCB Locate terminal block J2 ML AN 2 Feed the cable through the large hole with the other cables The RJ 45 jack should remain on the outside of the enclosure 3 The serial cable consists of four wires E Ht Two of the wires RS
