Visual Systems 84VP5/84VM5 Installation Guide (using four 42VM5 or 42VP5 Plasma Displays) (also a reference for optional Quad Mount used with 42VM5 or 42VP5) v1.3 Check Sum Example DFH 80H Command1 Unit ID1 60H Unit ID2 47H 01H 01H Command2 Data Length Data 08H Check Sum Total 208H 2) Error Processing • When the communication interval is vacant for more than 4 ms, thereafter a received Command 1 will be recognized. If, at this time, meaningful data cannot be recognized, that data will not be recognized (as valid data). • An ACK will not be returned unless the receive data error, the check sum error, and the receive data are all taken in. The control method of the set by Set ID When controlling two or more sets of plasma monitors, if the command using Set ID is used, it will become controllable individually. The example of the POWER ON command to the plasma monitor which set ID as "5" is shown below. It is not based on ID but is the POWER ON command to all sets. 9F 80 60 4E 00 CD In ID= "5", the value of ID-1=4 is set up. 9D 84 60 4E 00 CF The example of a change in the single mode of a 4th page multi-system configuration and the multi-mode is shown below. ID of the set used as a master(etc PC) is set to 50, and it assumes that ID is shaken by AUTO ID to each set. ID shaken at each set is as follows. Upper left set (master) ID = 50 = 32h Upper right set ID = 51 = 33h Lower right set ID = 52 = 34h Lower left set ID = 53 = 35h Transmission Data DD 81 63 03 03 03 01 00 CB DD 82 63 03 03 03 02 00 CD DD 83 63 03 03 03 03 00 CF DD 84 63 03 03 03 04 00 D1 Transmission of the above command performs a 4th page multi SPLIT display. Moreover, the following commands are published in order to change a 4th page multi-display into a single mode display. DF 80 60 03 03 01 01 00 C7 All sets become a single mode display by the above-mentioned command. Since this command does not specify Set ID, all sets execute it. *:Control by ID may not be able to be performed depending on connection with external control apparatus. www.necvisualsystems.com Page 8 of 14
