1. Introduction
This manual describes how the options for the GX-M/GF-M series and the GX-L/GF-L series
(comparator output, analog voltage output) work and how to get the most out of it in terms of
performance. Read this manual thoroughly before using and keep it at hand for future reference.
2. Features
The following options can be used for the GX-M/GF-M series and the GX-L/GF-L series.
GXM-04/GXL-04 Comparator output (with buzzer)/External contact input x 2/RS-232C
GXM-06/GXL-06 Analog voltage output/RS-232C
GXM-04/GXL-04: Comparator output/External contact input/RS-232C
The GXM-04/GXL-04 can compare the weighing value and preset threshold values and can
output the result to the contact output.
The GXM-04/GXL-04 are 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 GXM-04/GXL-04 can sound a buzzer according to the comparison result.
The GXM-04/GXL-04 are 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.
GXM-06/GXL-06: Analog voltage output/RS-232C
The GXM-06/GXL-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 1 V" range and "0.2 V to 1 V" range. The factory setting is "0 to 1 V"
range.

4. Installing the Option
Caution
Disconnect the AC adaptor before installing the option to the balance.
4.1. Installing the GXM-04/GXM-06
Install the GXM-04 and GXM-06 according to the following procedure.
(The installation procedure of the GXM-04 and GXM-06 is the same.)
Step1 Remove the two screws from the panel and remove
the RS-232C/USB board from the balance.
Step2 Pull gently and remove the two cables
from the RS-232C/USB board.
Step3 Insert the two cables into the sockets of the GXM-06 board.
Step4 Insert the rubber packing and plug the GXM-06 into
the balance.
Screw the panel of GXM-06.
Caution
When inserting the GXM-06, pay attention to the top and bottom orientation of the board.
The rubber packing has a deep groove on the balance side.

5. Function Table of Balance
The function table stores parameters that specify how to operate the balance, and it is used to
monitor 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 GXM-04/GXL-04 and the GXM-06/GXL-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.
Example of settings and menu structure (Example: the GXM-04)
Example : Set to " Center value using sample weight input " of " Input method " in " Comparator ".
Caution
The balance may not function properly, depending on the settings and the operating
environment. Be sure to set parameters correctly.
