Comparator output Contact-outputs, output the comparison results between the weighing data and upper/lower limit values, using HI , OK , and LO . Whether or not to sound a buzzer, depending on the results, can be selected. Analog output Two modes are available: To convert the specified weight value digits to voltage, and to convert the weight value, in the range from zero to the weighing capacity, to voltage. Output voltage range selection: Using the slide switch (0V~/0.
3. Function Table The function table reads or rewrites the parameters that are stored in the balance. When GX-04K or GX-06K is used, set the function table to specify the balance performance. These parameters are maintained in non-volatile memory, even if the AC adapter is removed. 3-1-1. Structure And Sequence Of The Function Table This function table menu consists of two layers. The first layer is the "Class" and the second layer is the "Item".

5-3. Connection Of The AD-8121B Printer Preset the following parameters to use the AD-8121B printer.
5-4. Description Of The Item “Data output mode” The parameter setting of "Data output mode (prt)" applies to the performance when the "Data memory (data)" parameter is set to "2" (to store the weighing data) and when the data is transmitted using the RS-232C interface. Key mode When the PRINT key is pressed with the stabilization indictor turned on, the balance outputs or stores the weighing data and the display blinks one time.
Interval memory mode The weighing data is periodically stored in memory. Example For periodical weighing without a personal computer command and to output all of the data, to a computer, at one time. The GX-K series can use time and date with "Time/Date output (5-td)". Required setting dout prt 3 Interval memory mode dout data 2 Data memory function is used dout int Interval time Optional setting dout 5-td1, 2, or 3 Adds the time and date. 5-5.
KF format 5if type 2 This is the Karl-Fischer moisture meter format and is used when the peripheral equipment can only communicate using this format. This format consists of fourteen characters excluding the terminator. This format has no header characters. The polarity sign is placed before the data, with spaces in place of leading zeros, if the data is not zero or overloaded. This format outputs the unit only for a stable value.
5-6. Description Of The Data Format Added To the Weighing Data ID number dout 5-id 1 Data number dout d-no 1 The number to identify a specific balance. This format consists of seven characters excluding the terminator. This format outputs the data number just before the data is transmitted using the RS-232C interface. This format consists of six characters excluding the terminator. When CSV format (5if type 5) is selected, the period ( . ) is replaced with a comma ( , ).

The unit Grain is not available for the GX-32K and GF-32K.
5-8. Connection To A Computer And The Use Of WinCT The balance is of the DCE type (Data Communication Equipment), which can be connected to a personal computer using the RS-232C interface. Before connection, read the personal computer manual thoroughly. Use a standard DCE cable for connection (cable type: straight-through). When the personal computer type is a DOS/V with a 9-pin port, use a straight-through cable with a 25-pin male connector and a 9-pin female connector.
5-9. Commands Note A command has a terminator added, that is specified using "5if Crlf" of the function table, and is sent to the balance. Commands to query weighing data C Cancels the S or SIR command. Q Requests the weighing data immediately. S Requests the weighing data when stabilized. SI Requests the weighing data immediately. SIR Requests the weighing data continuously. Commands to control the balance Requests the upper/lower limit value code number of the selected value.
Commands to control the balance Recalls the unit mass values in memory. mm: 01 to 50. UN:mm Changes the unit mass value. Use "g" of unit. ~ is space mark. Example: the unit mass value is 2000.0 g. UW:∗∗∗∗∗∗.∗~~g Command: UW: +002000.0~~g When a unit is required in commands such as a "PT:" command, use the 3-digit unit code of the A&D standard format. nnn indicates a three-digit numerical value. 5-10.
5-11. Control Using CTS And RTS Depending on the "Ct5" parameter of "Serial interface (5if)", the balance performs as follows: Ct5 0 Regardless of whether the balance can receive a command or not, the balance keeps the CTS line HI. The balance outputs data regardless of the condition of the RTS line. Ct5 1 The CTS line is kept Hi normally. When the balance can not receive the next command (Example: while the balance is processing the last command), the balance sets the CTS line to Lo.
