2.0 PROGRAMMING
The Model 1250B has three methods of programming, numeric menu, alphanumeric
menu, and serial port programming commands. Depending upon the serial port option
ordered, the serial programming commands will be either RS-232 ASCII commands or RS-
485 packet commands. (See Table 2.1 for a full listing of all programming menu items. See
Figure 2.1 for a simple programming flowchart. See Table 2.2 for a full listing of all serial
port programming commands and syntax.)
To access the numeric or alphanumeric programming menu, press the MENU key for
several seconds until the display goes blank, then press the SELECT/ENTER key. The
display should read “OP 0”. The default menu is the numeric menu. To choose the
alphanumeric menu, press the DOWN key to select OP 99. Press the SELECT/ENTER key,
the display should read “to OP”. Press the UP key. The display should read “run”. You are
now in the alphanumeric menu mode.
To change a parameter using the numeric or alphanumeric menus, select the parameter
to be changed from the menu, press the SELECT/ENTER key. The parameter’s present
setting will now be displayed. You can change the setting by pressing the UP or DOWN key.
To store the new setting, press the SELECT/ENTER key. The display will return to the
menu.
