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. See Table 2 in “1-2 Applicable Instruments”.
⋆3 CC-Link is a high-speed field network able to simutaneouslly 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 depends 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 is connected, displays the AD-4212C/D 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.

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
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.

12
 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.
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: 1.0 mm (AWG 26) to 1.2 mm (AWG 16)
 Twisted wire: 0.3 mm2 (AWG 22) to 0.75 mm2 (AWG 20)
Individual wire diameter 0.18 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.

3.5. Calibrating the AD-4212C
The following is the calibration procedure when the AD-4212C is connected.
(A calibration weight is used.)
Caution
 Do not allow vibration, drafts or temperature change to affect the AD-4212C
during calibration.
Caution on using an external calibration weight
 The accuracy of the weight can influence the accuracy of weighing.
Select an appropriate weight as listed below.
A calibration weight of 200 g is provided with the AD-4212C as a standard
accessory.

stored in non-volatile memory, 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.
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.
