1. INTRODUCTION
This manual describes how the AD-8923-CC remote controller works and how to get the most out of it interms 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 RS232C 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 andinformation data. With a high communication speed of 10 Mbps, CC-Link can achieve amaximum 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.
⋆4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.

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 theAC 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
CAUTIONUse 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 fromfunctioning 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.

4. FUNCTION SETTING
Function setting specifies the AD-8923-CC performance. The parameters are stored in non-volatilememory, and are maintained even if the power line or AC adapter is removed.
The function setting menu consists of two layers. The first layer is the “Class” and the second layer is the“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.

ExampleThis 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, theAD-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 valuesof CC-Link are changed in the function setting.

Prohibited writing in the internally reserved areas
Writing is prohibited in the internally reserved areas.
Writing in the remote output (RY) and the remote register (RWw) of the internally reserved areas
may cause the AD-8923-CC to malfunction.
Values of the remote input (RX) and the remote register (RWr) of the internally reserved areas are
not fixed.

6.2. Timing chart
Below examples are when the station number is set to 1.
When connecting to a power supply
When the AD-8923-CC is connected to a power supply and the CC-Link is ready, the request flag of
initialization (RX0018) becomes active.
The master station confirms that RX0018 is active, performs initialization and turns the reply flag of
initialization (RY0018) ON.
The AD-8923-CC turns the request flag of initialization (RX0018) OFF and turns the remote READY flag
(RX001B) ON.
Turn OFF the reply flag of initialization (RY0018) in the master station.
When the request flag of initialization(RX0018) is ON, the reply flag of

Requesting initialization from the master station
When requesting the initial data setting to the AD-8923-CC from the master station, turn the request flagof initial data setting (RY0019) ON while the remote READY flag (RX001B) is active.
The AD-8923-CC turns the remote READY flag (RX001B) OFF and performs initial data settings. Wheninitial data settings are complete, the reply flag of initial data setting (RX0019) is turned ON.

The CPU normal operation (RX0006) is a signal to check that the AD-8923-CC is connected to a power supply
and it functions normally. During normal operation, the signal is reversed at an interval of 0.5 to 1 second.

Using the function setting of, the decimal point position of the value displayed on the AD-8923-CC
and the decimal point position of the weight value output via CC-Link can be fixed.
In this way, even if the minimum display is switched using the SAMPLE key, the digit position for CCLink output does not change.

6.4. Sensitivity adjustment with the AD-4212C/F using the register of the CC-Link
The following describes the sensitivity adjustment procedure using the register of the CC-Link whenconnecting the AD-8923-CC to the AD-4212C/F. (Using an external weight)* Only AD-8923-CC software versions P2.05 or later are compatible with this function.
* When performing sensitivity adjustment using the key operation, refer to “3.5. Performing Sensitivity
Adjustment with the AD-4212C/F” for the details.
Caution on sensitivity adjustment
While the sensitivity adjustment is being carried out, take care to use these instruments in an environment
where they are not affected by vibration, drafts or temperature change.

Symptomappears.

(Bar display)remains and the weightvalue is not displayed.
The display flickers.

Description
Communication settings of the AD-8923-CC do not match with thoseof the weighing instrument.
Check the settings such as baud rate and parity and correct them asnecessary.
For details, refer to “3.1. Setting the weighing instrument and the AD8923-CC”.
Is the data output mode of the weighing instrument set to “stream mode”?
In a mode other than “stream mode”, the weight values are displayed
only when they are transmitted.
Check if the communication settings are correct.
Check if the cables are the correct type and are not damaged.
Electrical noise may cause this symptom.
Ground the FG terminal located on the rear of the AD-8923-CC.
