1. Introduction
This manual describes options for the GX-A series and GF-A series and how to get the most
out of them in terms of performance. Read this manual thoroughly before using the options and
keep it at hand for future reference.
2. Features
The following options can be used for the GX-A series and GF-A series.
GXA-03 Isolated RS-232C interface
GXA-04 Comparator output (with buzzer) / External contact input x 2
GXA-06 Analog voltage output
GXA-03: Isolated RS-232C interface
Commands from the PLC or other devices installed in the factory environment can be used to
make the following operations : output measurement data from the balance, input parameters
into the balance, control the balance, reference parameters of the balance, etc.
The RS-232C is equipped with a data format to manage the balance in accordance with GLP.
( Refer to the instruction manual of the balance. )
GXA-04: Comparator output / External contact input
The GXA-04 can compare the weighing value and preset threshold values and can output the
result to the contact output.
The GXA-04 is equipped with six contact outputs: "HH", "HI", "OK", "LO", "LL" of the
comparison output and "READY" output to indicate the status of the balance.
3-stage comparison or 5-stage comparison can be selected.
The GXA-04 can sound a buzzer according to the comparison result.
The GXA-04 is equipped with external control input terminals that can make the RE-ZERO
and PRINT key operations. An optional foot switch (AX-SW137-PRINT, AX-SW137-RE-
ZERO ) can be used.
GXA-06: Analog voltage output
The GXA-06 can output analog voltage in the following modes :
"mode where the specified digits of the weighing value are converted to voltage" and
"mode where weighing value is converted to voltage in range between gross zero or net zero
and full scale".
The voltage output range can be selected using the "0V /0.2V " switch on the panel.
It can be selected "0 to 1V" range and "0.2V to 1V" range. The factory setting is "0 to 1V" range.

4. Installing the Option
Caution
Installing the option board to the balance
Step1
Step2
Disconnect the AC adaptor before installing the option to the balance.
Remove the two screws from the panel.
Pull gently the cable and option board from
the balance.
Peel off the connector that is affixed
to the panel with double-sided tape
and insert it into the socket of the
option board.
Option panel: Confirm the layout of terminal, etc. on the option.
Socket : Confirm the position of the socket on the option.

Connector
Step3
Attach the option board to the balance.
Secure with the two screws removed in step 1.
Assembling the mini-DIN connector
You can use the GXA-04 ( AX-K0592 ) and GXA-06 ( AX-K0593 )
of the option cable assembled with the mini-DIN connector.
Step 1
Pass the cable through the rubber sleeve.
Step 2
Solder wires and terminal.
Step 3
Cover the terminal with the top metal
case and bottom metal case.
Step 4
Fasten wires with the top metal case.
Step 5
Insert the assembled parts into the
rubber sleeve.

5. Function Table of Balance
The function table stores parameters that specify how to operate the balance, and it is used to
mointor or update those parameters. These parameters are stored in memory even if the AC
adaptor is removed and are retained until overwritten. Balance operations are specified by this
table when using the GXA-03, GXA-04 and GXA-06. The table menu consists of two layers as shown in the diagram below. The first layer is the “Class” and the second layer is the “Item”. Each item stores a "parameter". The last displayed parameter is in effect. After the
PRINT key is pressed, these updated parameters are applied to operations of the balance.

Caution
The balance may not function properly, depending on the settings and the operating environment. Be sure to set parameters correctly.

5.1. Operation Keys and Display of Function Table
The 〇 indicates that the parameter displayed is in effect.
Enters the function table when pressed and held in the weighing mode. Selects the class or item in the function table.
Changes the parameter.
Moves to an item in the class when a class is displayed. Stores the new parameter and displays the next class when an item is displayed.
Cancels new parameter and displays the next class when an item is displayed. Exits the function table and returns to the weighing mode when a class is displayed.
