Do not disassemble the interface. It may cause damage or malfunction,
which is not included in the warranty.
Immediately stop using the interface if an abnormality occurs.

4. Connection to Other Devices

The power for the AD-8561 can be supplied from the counting scale withan accessory cable. When another cable is used, an AC adapter for power
supply may be required. (Refer to “4-1. Connection to Power Supply.”)
Make sure to check the rating of the AC adapter before attaching it.
Inappropriate power supply may cause malfunction or damage to theinternal circuitry.

MagnetMagnets are not strong enough to secure the interface to a wall. To attach
to a wall, first attach the AD-8561 to a GC-14, an option for the counting
scale, with screws, and then attach the GC-14 to a wall (with screws or byhanging it on a wall). For the details, refer to the instruction manual for theGC-14.

1. Introduction
This manual describes how to handle the Multi-Interface AD-8561. Read theinstruction manual thoroughly before use.
For the information on the AD-8561 and its related products, please refer tothe A&D website (https://www.aandd.jp).

4-1. Connection to Power Supply

Magnets are used for simple fixation.

<How to remove the magnets for attaching the interface>5-1. RS-232C Connector (D-sub 9 pin): PRINTER

Supply power

Communication between the counting scale and a printer (or PC) isoperable with an RS-232C interface.
Transmission system: EIA RS-232C
Transmission form: Asynchronous, bidirectional, half-duplex
Data format:

When the accessory cable is not used, an AC adapter should be used tosupply power from the DC jack.
When using a commercially available cable to which the 9th pin of theconnector is not connected
When communicating between the counting scale and AD-8561 at a
distance longer than 1 m* A cable longer than 1 m, which is optionally available, is not connectedto the 9th pin of the connector and therefore requires power supply
from an AC adapter. (Refer to (3) in “8-3. Optional Devices.”)

Pin layout

Make sure to check the specifications when using an AC adapter. An AC
adapter with a center negative plug that outputs DC 9 to 12V is usable.
The main unit is activated when it is connected to the counting scale orwhen an AC adapter is inserted into the DC jack. Once it is activated, ablue LED light is turned on.
To restart the interface, remove the cable or AC adapter and confirm that
the LED light is turned off. Then, reconnect it to turn the power on.

Attach a barcode reader or keyboard to send entered text to the counting
scale.
Transmission system : USB 2.0Connector: Type A
Device class: HID
Current consumption : 300 mA max.
Once the device is connected, the color of the LED light changes from blue
to white or yellow.
The color does not change if the AD-8561 cannot recognize theconnected device. In this case, restart the AD-8561 and reconnect thedevice.
Red LED light blinks when a device of not supported device class isconnected. Note that data may be broken if a USB memory ismistakenly attached.
Modes and data to transmit * Modes are selectable. (Refer to “6. Functions.”)
Key mode: To be used when the counting scale searches/registers an ID or item.
: The last 6 digits of the input data arerecognized as an ID.
- For searching/registering item code : Up to 20 digits from the beginning of
the input data are recognized as anitem code and forward-matching
searching can be done.

[PRINTER]
Relay outputs the comparator result of the counting scale.
Maximum rating of the relay output
Maximum voltage: 50V DC
Maximum current: 100mA DC
Maximum on-resistance : 8 Ω
The upper/lower limit values cannot be set with the AD-8561.
They should be set with the counting scale.
Set the function F-06-10 for the counting scale to ‘1.’Pin layout- For commands, refer to the instruction manual for the counting scale.
- Up to 64 digits in a string can be transmitted.
(The data is deleted without being sent if more than 64 digits are input. Restart
the AD-8561 to prevent errors in a subsequent communication data.)

CautionBarcode reader

Set your barcode reader to add a linefeed code ’Enter’ or ‘Tab’ to the suffix of data.

Keyboard- In command mode, the counting scale cannot recognize the input data
until ’Enter’ key is pressed. Make sure to press ’Enter’ key at the end of eachdata entry. Characters are not shown while being entered.
- Re-enter from the beginning if wrong characters are entered.
