RS-232C MONITOR ID and RS-232C CONTROL Up to 26 individual monitors can be controlled through a daisy chain via RS-232C connection. English This Plasma monitor can be controlled via personal computer using an RS-232C connection. Functions that can be controlled via RS-232C: • Powering ON or OFF • Switching input signals NOTE: If your PC (IBM or IBM compatible) is equipped only with a 25-pin serial port connector, a 25-pin serial port adapter is required. Contact your dealer for details. NOTE: In order to function, the RS-232C OUT terminal can only be connected to another monitor of the same model. Do not connect to other types of equipment. 1. Connect PC to the monitor. Connect a PC's RS-232C control output to the monitor's RS-232C input. You can then connect the RS-232C output from this monitor to another monitor's RS-232C input. Up to 26 monitors can be connected using RS-232C. 2. Set Monitor ID and RS-232C Control mode. For proper operation, the Monitor ID should be set in the OSD menu of each monitor that is in the chain. The Monitor ID can be set under the "OPTION3" menu in the OSD. The Monitor ID number can be set within a range from 1 to 26 or set to "ALL". No two monitors should share the same Monitor ID number. It is recommended to number each monitor in a daisy chain sequentially from 1. The first monitor in the daisy chain is designated as the primary monitor. Subsequent monitors with the chain are secondary monitors. In the "OPTION3" menu on the first monitor in the RS-232C daisy chain set the "RS232C CONTROL" to "NORMAL". Set the "RS232C CONTROL" to "2ND" on all other monitors. This monitor uses RXD, TXD and GND lines for RS-232C control. The reverse type cable (null modem cable) should be used for RS-232C control.
