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.

Use the display on the balance.
Note 5) Do not operate by using the key on the AD-8923-CC.
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.)

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”.
To enter the function setting of the AD-8923-CC, press the CAL key while holding down
the ON:OFF key.
For details, refer to “4. FUNCTION SETTING”.
