3-48 BOP HIPWR 1113153.5.3.1.2 CONFIGURE DEVICE CLEAR (DCL) CONTROLThe device clear (DCL) and selected device clear can be set to operate in two modes. In theMATE mode, when the device clear is received, the output of the power supply is set to zerovolts. In the SCPI mode sending DCL or selected DCL has no effect on output voltage and cur-rent as required by IEEE specification 488.2. The factory default value is SCPI mode.To change the Device Clear configuration press % from the power-up screen, then press ! toenter the Interface menu (see Table 3-16) Highlight Device Clear and press !, then highlightSCPI or MATE and press $ to save. Press $ to save for power-up or % to apply thechanges (without saving for power-up) and exit.3.5.3.1.3 DETERMINING WHETHER *RST COMMAND SETS THE OUTPUT OFF OR ONThe user can control whether the *RST command (see PAR. A.11) sets the output on or off.Refer to PAR. 3.3.6 and Table 3-6 for a full explanation plus CAUTIONS and WARNINGS asso-ciated with setting the output on or off, depending on which load type is selected.From the power-up screen press %, and note whether “*RST set Output” setting is asdesired. To modify highlight Interface Settings (see Table 3-16) and press !, then highlight Onor Off and press ! to save. Press $ to save for power-up or % to apply the changes (with-out saving for power-up) and exit.3.5.3.2 RS 232 SERIAL PORT SETUPParagraphs 3.5.3.2.1 through 3.5.3.2.3 below describe the setup required for the BOP to com-municate via the RS 232C Serial bus using SCPI commands.3.5.3.2.1 SELECT BAUD RATETo change the Baud Rate configuration press % from the power-up screen, then press ! toenter the Interface menu (see Table 3-16). Highlight Baud Rate and press !, then highlight theOff (to disable the serial port), 9600 or 19,200 and press $ to save. Press $ to save forpower-up or % to apply the changes (without saving for power-up) and exit.3.5.3.2.2 CONFIGURE XON/XOFF PROTOCOLFrom the power-up screen press %, then press ! to enter the Interface menu (see Table 3-16), highlight SERIAL XON/XOFF and press !. Highlight the desired option and press $ tosave, then press $ to save for power-up or % to apply the changes (without saving forpower-up) and exit.Enable - Allows BOP to control when data is received (see PAR. 3.5.6.2.1 for a description ofXon/Xoff protocol).Disable - Disables XON/XOFF. If both Serial XON/XOFF and Prompt functions are disabled,Echo mode is set (see PAR. 3.5.6.2.2 for a description of echo mode).3.5.3.2.3 CONFIGURE PROMPT MODEFrom the power-up screen press %, then press ! to enter the Interface menu (see Table 3-16). Highlight Serial Prompt and press !, highlight the desired option and press $ to save,then press % to apply the changes (without saving for power-up) and exit, or press $ to savefor power-up (see PAR. 3.5.6.2.3 for a description of prompt mode).
