１INTRODUCTION
The AD-8922 is a remote controller. Read this manual completely before using the AD-8922 in order to
ensure a sufficient understanding for proper use.
１-１Outline
The AD-8922 is connected to an A&D manufactured weighing instrument, using the RS-232C serial interface.
zDisplays the weighing data transmitted by the weighing instrument.
zKey operations remotely control the weighing instrument.
(Entering the function setting mode of the weighing instrument or calibration using an external weight
is not available. Available operations depend on the weighing instrument used. See Table 2 in "1-2
Applicable Instruments".)
zThe data the AD-8922 receives can be output, using the RS-232C serial interface. So, external
devices such as a personal computer or a printer can be connected to the AD-8922.
zCan be panel-mounted.
zVarious options such as BCD output, comparator output, current loop input and analog output are
available. For details, refer to "9 OPTIONS" and the following relevant chapters.

The AD-8922 functions in two ways as follows, depending on the weighing instrument used:
zA remote controller that displays the weighing data and remotely controls the weighing instrument.
zA remote display that displays the weighing data.
Available key operations depend on the weighing instrument used, as shown below. Set the command set
"C5et" of the function setting, appropriate to the weighing instrument.

１-３Compliance
１-３-１Compliance with FCC Rules
Please note that this equipment generates, uses and can radiate radio frequency energy. This
equipment has been tested and has been found to comply with the limits of a Class A computing
device pursuant to Subpart J of Part 15 of FCC rules. These rules are designed to provide
reasonable protection against interference when equipment is operated in a commercial
environment. If this unit is operated in a residential area, it may cause some interference and under
these circumstances the user would be required to take, at his own expense, whatever measures
are necessary to eliminate the interference.
(FCC = Federal Communications Commission in the U.S.A.)
１-３-２Compliance with EMC Directives
This device features radio interference suppression in compliance with valid EC
Regulation 89/336/EEC.

２DESCRIPTION OF EACH PART
Note: Please confirm that the AC adapter type is correct for your local voltage and receptacle
type.
A substitute communications cable, listed below, may be provided as specified when
ordering the AD-8922.
•D-Sub 9-pin to D-Sub 9-pin (AX-KO2466-200)
•DIN 7-pin to D-Sub 9-pin (AX-KO1786-200)

２-１Display
zDisplays the weighing data and the unit (or mode) received. The unit (or mode) may be different from
that of the weighing instrument.
zTurns on the stabilization indicator when the header of the weighing data received is "ST", "QT", or
"WT".
zTurns on the comparator indicator when the comparison results are added to the data received.
Applicable to GX-K, GF-K, GP and AD-4212. (Function setting "Cp-r")
zWhen nothing has been received for two seconds or more, the bar display [- - - - -] appears. By
changing the function setting, the previous data received is displayed until the next data is received
(Hold display). During the hold display, the hold indicator is turned on.
Note: When the data is in eight digits, the highest-order digit is displayed in the upper
left corner as shown below.
For example, if the weighing data is 101.00000 g, the display is like .
２-２Key Operation
Available key operations to control the weighing instrument depend on the weighing instrument used. For
details, see Table 2 in " 1-2 Applicable Instruments".
Set the command set "C5et" of the function setting, appropriate to the weighing instrument.
To enter the function setting mode of the AD-8922, press and hold the ON:OFF key and press the CAL
key.
The weighing instrument has its own function settings and the AD-8922 can not change those settings.
２-３Connectors
２-３-１Connector to the weighing instrument (BALANCE / SCALE) ... D-Sub 9-pin male
Used to connect to the weighing instrument. The cable used for connection depends on the instrument.
For details, refer to the instruction manual of the weighing instrument.
２-３-２Connector to the external device (PC / PRINTER) ... DIN 8-pin female
Used to connect to an external device such as a personal computer or a printer (AD-8121B). The cable
used for connection depends on the device. For details, refer to the instruction manual of the device.

2. Set the command set "C5et" of the function setting, appropriate to the weighing instrument. See Table 2
in "1-2 Applicable Instruments".
Note: Some items may not be available for the instrument used. For details on setting,
refer to the instruction manual of each weighing instrument.
When connected to an external device such as a personal computer or a printer, set the output
mode "out" and time out "Hold" of the function setting, and set the data output mode of the
weighing instrument, appropriate to the use. (See Table 3 in "3-5 Example of Use".)
３-２Connecting the AD-8922
For information on cables required for connection, see Table 1 in " 1-2 Applicable Instruments".

３-３Turning the Power on
Insert the AC adapter plug into the AC adapter jack located on
the rear of the AD-8922. Plug the AC adapter into an appropriate
electrical outlet.
３-４Operation
zThe AD-8922 displays the weighing data transmitted by the weighing instrument used.
zThe AD-8922 key operations remotely control the weighing instrument.
Available operations depend on the weighing instrument. See Table 2 in "1-2 Applicable Instruments".
３-５Example of Use
zA personal computer is connected to the AD-8922 and the weighing data can be transmitted to the
personal computer, using Windows communication tools (WinCT).
zTo protect against inadvertent operations, the AD-8922 keys can be disabled. (Function setting
"C5et 0").
zWhen nothing has been received for two seconds or more, the bar display [- - - - -] appears. By
changing the function setting, the previous data received is displayed until the next data is received
(Hold display). (Function setting "Hold 1 ")
