SAFETY PRECAUTIONS
All safety messages are identified by the following, "WARNING" or
"CAUTION", of ANSI Z535.4 (American National Standard Institute: Product Safety
Signs and Labels). The meanings are as follows:
This manual is subject to change without notice at any time to improve the product.
Product specifications are subject to change without any obligation on
the part of the manufacturer.
When using the AD-1611, the following safety precautions should
always be observed.
CAUTION
Do not disassemble the AD-1611. Disassembling may cause damage to
the AD-1611. Damage caused by disassembling will not be covered by
the warranty. Contact your local A&D dealer if the AD-1611 needs
service or repair.
If a problem has occurred and you cannot resolve it, stop using the
AD-1611.
PRECAUTIONS FOR USE
AD-1611 main body
The AD-1611 is not explosion-proof or waterproof. Do not place it where
there is a risk of explosion or where it may get wet.
When the optical port is not used or the AD-1611 is stored, attach the
protective cap provided to the port. Otherwise, dust may enter the
connector in the optical port and cause a communication error.
Power supply
Power is supplied to the AD-1611 by the accessory AC adapter or by a
personal computer (PC) connected using the accessory USB cable.
When the USB cable is used for communication, power is supplied by a
PC. Only a PC can be connected to the USB port. Do not connect other
devices to the USB port nor take power from an outside source.
When an RS-232C cable is used for communication, use the AC
adapter to supply power.
WARNING A potentially hazardous situation which, if not
avoided, could result in death or serious injury.
CAUTION A potentially hazardous situation which, if not
avoided, may result in minor or moderate injury.

Communication
The AD-1611 is a unidirectional communication unit to receive data
(optical signals) output from a balance/scale and transmit electric
signals to external devices/PC through RS-232C or USB. It cannot
transmit commands from external devices/PC to the balance/scale.
To use the USB cable, install a USB driver beforehand. Refer to “3.2.
Preparation”.
When a PC is used to view the output data, the Windows
communication tools software (WinCT) can be used to see the results.
Refer to “3.2. Preparation”.
If communication is not stable, use the ground terminal to ground the
AD-1611. Refer to “2.1. AD-1611”.
Optical fiber cable
Use the recommended cables below.
Using other cables may cause damage to the connector or may cause a
communication error.
Cables available as options (recommended)
AX-KS5456-010 (10 m)
AX-KS5456-030 (30 m)
AX-KS5456-060 (60 m)
If you want to use a commercially available cable, use an H-PCF (Hard
plastic clad fiber, 200/230 m) cable with an F05 connector (IEC 60874-17,
F05 type).
To prevent cables from breaking, do not bend the cables sharply or lay
cables on the ground when performing wiring.
The minimum bending radius of the optional cables is 30 mm.
A loose cable may cause a communication error. Hold the connector by
the surfaces with no lever and insert it until it clicks into place.

1. INTRODUCTION
This manual describes how the AD-1611 Optical Communication Adapter
works and how to get the most out of it in terms of performance.
Read this manual completely before using the AD-1611.
The AD-1611 is a relay device to output signals from a balance/scale to
an external device or a PC. When connected to a balance/scale with the
optical connector, the AD-1611 converts optical signals to electric signals
and output them through RS-232C or USB.

3.2. Preparation
1 When USB is used:
Install a USB driver on a PC.
A USB driver is available for download at our website:
http://www.aandd.jp/products/software/software.html
2 When the AD-1611 is connected to a PC:
Install the Windows communication tools software (WinCT) on a PC.
WinCT is also available for download at our website:
http://www.aandd.jp/products/software/software.html
3 Set the values of parity, data bits and baud rate for the external device or
PC, the same as those for the balance/scale.

3.3. Connection
Example 1: To output data from an explosion-proof balance through the
USB port
Example 2: To output data from a balance through the RS-232C port.
No setting is required for the AD-1611.
When the AD-1611 is used for the first time, the cables are reconnected or
the power is turned on, such as after the balance/scale battery replacement,
check as follows before use:
Press the PRINT key on the balance/scale two or three times to confirm
that the weight value is displayed in a stable way on the external device or
PC

4. LED OPERATION
The LED blinks when the AD-1611 receives data.
Whether the LED blinks or turns off depends on the serial interface data
output mode setting of the balance/scale. Refer to the balance/scale
instruction manual to set the data output mode on the balance/scale.
4.1. PRINT key mode
