1. INTRODUCTION
This manual describes how the AD-8923-CC remote controller works and how to get the most out of it in
terms of performance.
Read this manual thoroughly before using the AD-8923-CC and keep it at hand for future reference.
1.1. Features
Connecting the AD-8923-CC remote controller to a weighing instrument will enable transmission of RS-
232C weighing data from the weighing instrument to a PLC using CC-Link (⋆1).
Displays the weighing data transmitted from the weighing instrument.
Key operations remotely control the weighing instrument (⋆2).
Using the CC-Link interface, the AD-8923-CC can receive the weighing data or perform re-zeroing of
the weighing instrument.
Note
⋆1 The AD-8923-CC CC-Link is a remote device station of CC-Link ver. 1.10.
⋆2 Entering the function setting mode of the weighing instrument is not available. Available
operations depend on the weighing instrument used. Refer to Table 2 in “1.2. Applicable
Instruments”.
⋆3 CC-Link is a high-speed field network able to simultaneously handle both control and
information data. With a high communication speed of 10 Mbps, CC-Link can achieve a
maximum transmission distance of 100 meters and connect to 64 stations.
When a CC-Link network is configured using the AD-8923-CC, the maximum number of stations
(or units) will be 42.

5
1.2. Applicable Instruments
The AD-8923-CC functions in two ways as follows, depending on the weighing instrument used:
A remote controller that displays the weighing data and remotely controls the weighing instrument.
A remote display that displays the weighing data.
Available key operations depend on the weighing instrument used. (Refer to “Table 2”)
For weighing instruments not listed in this table, please refer to the A&D website.

2.1. Display
Displays the weighing data received. When the unit is “g” (gram), the unit indicator turns on. If the
balance outputs RS-232C weighing data that exceeds six digits, the AD-8923-CC does not display the
high-end digits. (2 highest digits for an 8 digit display)
Weight value of the CC-link is output even if it exceeds six digits.
When the weight value is stable (the header of the weighing data received is “ST”), the STABLE
indicator turns on.
If the AD-8923-CC does not receive the weighing data for two seconds or more, is
displayed (Bar display).
When AD-4212C/D/F is connected, displays the AD-4212C/D/F weighing speed that is currently
set, by turning on the weighing speed indicator. When connected to other instruments, the AD-8923-
CC weighing speed indicators have no function.
2.2. Keys
Used to operate the weighing instruments. For details, refer to “3.4. Operation”.

3.3. Turning the power on
As a power supply, an external 24-VDC power supply (24 VDC±10%/700mA) or a 12-VDC AC adapter
can be used.
When connected to the following instruments, power can be supplied to both instruments by plugging the
AC adapter into either the weighing instrument or the AD-8923-CC.
(Both instruments can have their AC adapter connected at the same time.)
Compatible models: AD-4212C/D/F, FZ, FX, GX-A, GF-A, GX-M, GF-M, GX-L, GF-L, HR-AZ, HR-A
When the external 24-VDC power supply is used
Connect an external 24-VDC power supply to the DC input terminal located on the rear of the AD-8923-CC.
Precautions on using the external power supply
CAUTION
Use a power supply within the rated voltage range (24 VDC±10%).
Never use a power supply with a voltage exceeding the rated range.
It may cause damage or heat buildup.
The AD-8923-CC may not function properly.
Ground the FG terminal of the switching power supply used.
To avoid electrical shock and increase the system safety.
To increase the resistance against noises.
Do not share the power line with other devices.
Strong noises introduced from other devices may cause damage to the AD-8923-CC.
Inrush current from other devices may cause the AD-8923-CC not to start up properly.
Circuit configuration of the AD-8923-CC may affect other devices to prevent them from
functioning properly.
Select a switching power supply with a capacity of approximately 700mA for each AD-8923-CC.
Note that the AD-8923-CC may not start up with a capacity less than 700mA.
If the power supply capacity is not sufficient, the AD-8923-CC may not function properly.
Be sure to add a noise filter on the front end of the switching power supply and ground the FG
terminal.
This will increase the resistance against noises.
Be sure to ground the FG terminal of the AD-8923-CC and weighing instruments.
This will increase the resistance against noises.

13
Cable connection
CAUTION
Before inserting the power line, make sure that the power to the AD-8923-CC is turned off.
(1) Inserting the power line
Press down the release button on the DC
input terminal using a screwdriver and
insert the power line.
The recommended stripping length for the
power line is 10 mm.
Applicable wire range
Single wire: φ1.0 mm (AWG 26) to φ1.2 mm (AWG 16)
Twisted wire: 0.3 mm2(AWG 22) to 0.75 mm2(AWG 20)
Individual wire diameter φ0.18 mm or greater
(2) Securing or removing the power line
To secure the power line, return the release button to the initial position using the screwdriver.
The power line will be locked. To remove the power line, press the release button again using
the screwdriver, unlocking the power line.
When the AC adapter is used
Insert the AC adapter plug into the AC adapter
input jack located on the rear of the AD-8923-CC
and insert the AC adapter into an electrical outlet.
3.4. Operation
Displays the data transmitted by the weighing instrument connected.
The keys on the AD-8923-CC can control the weighing instrument. The key operation depends on the
weighing instrument connected. For details, refer to “Table 2” of “1.2. Applicable Instruments”.

“Item”. Each item stores a parameter.
Press the SAMPLE key to select an item and press the RE-ZERO key to change the parameter.
Then, press the PRINT key to store the new parameter.
Example
This example sets “Baud rate” to “9600 bps”.
Note
The AD-8923-CC may not function properly, depending on the settings and operating
environment. Check the settings and change them as necessary.

6. CC-LINK CONNECTOR
The AD-8923-CC CC-Link is a remote device station of CC-Link ver.1.10. When a CC-Link is used, the
AD-8923-CC can be controlled by the PLC remote I/O or remote registers. So, the program can be
simple. And connection to a PLC is simple, thus, a weighing system can be built easily. The setting values
of CC-Link are changed in the function setting .
