B. DMD-480-S2 SERIES DIP SWITCH SETTINGS 1. SET THE DESIRED ADDRESS FOR EACH UNIT BY SETTING SWITCHES 1-6. BY SETTING THIS ADDRESS, THE UNIT IS GIVEN ITS OWN IDENTITY TO WHICH THE HOST COMPUTER WILL IDENTIFY WITH. • THE ADDRESS RANGE IS FROM 0 - 63 (DECIMAL) OR 111111 (BINARY). (REFER TO EXAMPLES IN TABLE 3). • SWITCH “ON” = 0; SWITCH “OFF” = 1 2. SET THE DESIRED MODE OF OPERATION FOR THE 4570-232 USING SWITCHES 7 & 8. (REFER TO TABLE 2 FOR DEFINING MODES OF OPERATIONS) MODE 3 IS USED FOR DIAGNOSTIC PURPOSES. TABLE 2. SW 7 SW 8 MODE DESCRIPTION ON ON 0 OPERATE MODE: Operate Mode: Unit Outputs a reading whenever it is addressed by the the host computer. OFF ON 1 TEST MODE: Unit outputs a reading every 0.33 seconds continuously without being addressed ON OFF 2 UNDEFINED: OFF OFF 3 TEST MODE: Unit outputs a message " MODE 3: Version: 941124 Address: 01" continuously. BINARY = 10101. DECIMAL = 1 + 0 + 4 + 0 + 16 + 0 = 2. C.

PLEASE FEEL FREE TO MAKE ANY CUSTOM MODIFICATIONS TO THE SOFTWARE AS NEEDED. IT IS RECOMMENDED THAT THE USER MAKE A BACKUP COPY OF THE ORIGINAL OMEGA SOFTWARE BEFORE MODIFYING. 1. TO EXECUTE THE OMEGA C4500 SOFTWARE, QBASIC OR GWBASIC MUST BE LOADED ON YOUR COMPUTER. 2. TO BEGIN THE SOFTWARE SETUP, YOU MUST LOAD AND EXECUTE THE SUPPLIED OMEGA PROGRAM, “C4500.BAS” WITHIN QBASIC OR GWBASIC. D. SETUP MENU THE FIRST MENU TO APPEAR IS THE “SETUP MENU” IF YOU WANT TO SAVE ANY SETTINGS WHICH WILL BE ENTERED INTO THE PROGRAM, YOU WILL WANT TO ENTER THOSE SETTINGS DIRECTLY INTO THE SOFTWARE AND SAVE THE SOFTWARE WITH AN APPLICATION NAME (XXXXX.BAS).

OPTION 0 [RETURN TO OPERATION MENU]: SELECTING THIS OPTION WILL RETURN YOU TO THE OPERATION MENU. 2. OPTION 1 [SELECT COMMUNICATIONS PORT]: THIS OPTION ALLOWS THE SELECTION OF EITHER COM1 OR COM2 AS THE COMMUNICATIONS PORT FOR THE DMD-480-S2 SERIES AND THE USERS COMPUTER. COM3 AND COM4 ARE NOT ALLOWED. THE SETTING OF THE COMMUNICATIONS PORT IS ALWAYS NECESSARY FOR PROPER OPERATION OF THE DMD-480-S2 SERIES IN BOTH THE OPERATION AND TEST MODES. 3. OPTION 2 [SET SCALING EQUATION]: THIS OPTION ALLOWS THE USER TO SELECT COEFFICIENTS OF A SCALING EQUATION. THE SCALING EQUATION PROVIDES FOR BOTH A SCALE FACTOR (A) AND A FIXED OFFSET (C). THE SCALING EQUATION IS: VALUE = C + (A x READING) THE SETTING OF THE SCALING EQUATION ONLY APPLIES TO THE “OPERATION MODE”. (REFER TO SECTION F FOR A DESCRIPTION ON SETTING THE SCALING EQUATION.) 4. OPTION 3 [SELECT DATA DESTINATION]: THIS OPTION ALLOWS THE USER TO STORE DATA IN ONE OF 3 MODES. THE DATA MAY BE DISPLAYED ON THE COMPUTER SCREEN ONLY, SENT TO A FILE ONLY, OR BOTH. THIS OPTION APPLIES ONLY TO THE “OPERATION MODE”. (REFER TO SECTION G FOR MORE INFORMATION ON STORING DATA.) 5. OPTION 4 [DATA COLLECTION METHOD]: THIS OPTION ALLOWS THE USER TO COLLECT DATA IN 3 DIFFERENT WAYS AND ONLY APPLIES TO THE OPERATE MODE, NOT THE TEST MODE. 1) TAKE A READING EVERY “Y” SECONDS, WHERE “Y” IS ONE SECOND MINIMUM, FOR A TOTAL “A” MINUTES. 2) START TAKING DATA EVERY “Y” SECONDS AT TIME “A” UNTIL TIME “B”. 3) TAKE DATA EVERY “Y” SECONDS STARTING NOW AND CONTINUE READING DATA FOREVER. THIS IS THE DEFAULT METHOD FOR THE OPERATE MODE. BY DEFAULT, THE VALUE FOR “Y” MUS...
