The first way is to enter the configuration parameters directly from the front plate keyboard of the M3000 This method is also referred to as LCD programming During LCD programming the configuration parameters are displayed in the liquid crystal display while the operator is allowed to alter the state of each parameter The other way is to program the M3000 through the unit RS232 interface Important note The switch located on the rear left side of the M3000 must be in program mode PROG to allow programming from either the keyboard and or the RS232 interface The procedure of LCD programming is much like the programming procedures that you might already know from VCRs televisions and other microprocessor based products The operator is able to move around between the configuration parameters through the use of a selection key Each parameter of the configuration can be modified by toggling or by simply entering the new value from the numeric keys of the unit keyboard RS232 programming involves the use of a standard PC with Windows 95 Windows 98 Windows 2000 or Windows XP operation system SELCO has developed a user friendly application called the M3092 Programmer This application enables the operator to program the M3000 through use of the built in RS232 interface The parameters are entered in very much the same way as in a Microsoft Excel Spreadsheet This method of programming is ideal for setting up a M3000 from scratch Th
