DMS is CT-212 (STB) + 8120. CT212 is Master , 8120 is Slave. CT212 through CCIR656 and I2S to 8120 link Ethernet. PC Client AP is Faraplayer. Local OSD only setup CT-212. PC Client IE remote setup 8120. 8120 Com Port #1 for Original Console Control. 8120 Com Port #2 need Open for CT212 system comminucation. Mustek CT212 Com Port to PC is OK. Now Our Engineer Jerry try use SDK Open 8120 Com Port #2 is Fail. If 8120 Com Port #2 is OK. Mustek's RD Engineer will porting DMS command protocal. Could you release 8120 Com Port #2 relation paper to us ? Fixed this issue ASAP. DMS Schesule : Aug / End : Customer Demostration. Oct / End : MP Best Regards Brown Yu
