SAFETY PRECAUTIONSAll 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:
WARNINGCAUTION

A potentially hazardous situation which, if not
avoided, could result in death or serious injury.
A potentially hazardous situation which, if notavoided, may result in minor or moderate injury.

 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 tothe 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 theAD-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 theprotective cap provided to the port. Otherwise, dust may enter theconnector 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 apersonal computer (PC) connected using the accessory USB cable.
 When the USB cable is used for communication, power is supplied by aPC. Only a PC can be connected to the USB port. Do not connect otherdevices 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.

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 Windowscommunication 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 theAD-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 acommunication 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 (Hardplastic clad fiber, 200/230 µm) 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.

COMPLIANCE WITH FCC RULES
Please note that this equipment generates, uses and can radiate radio
frequency energy. This equipment has been tested and has been found tocomply with the limits of Class A digital devices pursuant to Part 15 of FCC
rules. These rules are designed to provide reasonable protection againstinterference when equipment is operated in a commercial environment. If
this unit is operated in a residential area, it may cause some interference
and under these circumstances the user would be required to take, at hisown expense, whatever measures are necessary to eliminate theinterference. (FCC = Federal Communications Commission in the U.S.A.)

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 toan external device or a PC. When connected to a balance/scale with theoptical 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:
https://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:
https://www.aandd.jp/products/software/software.html
3 Set the values of parity, data bits and baud rate for the external device orPC, the same as those for the balance/scale.

43.3. Connection
Example 1: To output data from an explosion-proof balance through theUSB 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 OPERATIONThe 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.
