It utilizes PLD (Programmable Logic Device), in order to establish both multi-channel discrete commands and serial commands by keeping its weight light. By using an ALTERA's FPGA device from MAX 7000 family, the first trial product was given in 2001. Through an onboard trial performed on August 26 2001, the new command decoder was found to work in an environment where balloons are used. In this first trial, power was not optimized, and its current consumption appeared to be very high, approximately 100 mA. This problem was fixed in a 2nd trial product developed in 2002 to 2003. The 2nd trial product utilizes the CPLD device, CoolRunner XPLA3, given by Xilinx, and established very low current consumption, approximately 10 mA. It also supports 20 channel discrete commands and 8 bit serial commands. The basic specifications were confirmed through onboard trial on September 19, 2003.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
