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 and the AD-4212C series
production weighing unit will enable transmission of the weight data to a
PLC using CC-Link.
zDisplays the weight data transmitted from the AD-4212C.
zCan change the weighing speed of the AD-4212C, calibrate the
AD-4212C using an external calibration weight and share the power
supply with the AD-4212C.
Note
When the AD-4212C is used as the weighing instrument,
connecting power to either the AD-8923-CC or the AD-4212C
will supply power to both devices. Refer to “3.3. Turning the
power on.”
zUsing the CC-Link interface, one CC-Link master station can control up to
42 units consisting of an AD-8923-CC and AD-4212C, to receive data or
perform re-zeroing.
Note
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 the
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.

Terminating resistor 110Ω1/2 W 130Ω1/2 W
Terminating resistors are not provided.
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.
Note
When the AD-4212C is used, connecting power to either the
AD-8923-CC or the AD-4212C will supply power to both devices.
So, instead of the AD-8923-CC, using the AC adapter on the
AD-4212C will supply power to the AD-8923-CC.
If the power is connected to both, no problems occur because the
power to be used is selected automatically.
Connect a terminating resistor
only to the stations at each end
of the network.

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
zUse 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.
zGround the FG terminal of the switching power supply used.
•To avoid electrical shock and increase the system safety.
•To increase the resistance against noises.
zDo 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.
zSelect 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.
zBe 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.
zBe sure to ground the FG terminal of the AD-8923-CC and the AD-4212C.
•This will increase the resistance against noises.

4. FUNCTION SETTING
Function setting specifies the AD-8923-CC performance. The parameters are
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.
The setting values of CC-Link are changed in the function setting CCl.
