Using the AD-8527 
When operating this instrument, be sure to observe the 
following: 
 
Caution  
 
•Do not open the case to repair the AD-8527. Only 
qualified personnel can do that. Attempting repairs 
yourself may cause damage to the AD-8527. Damage 
caused by attempting to do the repair yourself will void 
the warranty. 
 
Precautions on Usage 
 
Caution  
 
•With the cap attached over the connectors, the 
AD-8527 is protected against water splashing 
(equivalent to IP65). Please note that it will not endure 
immersion in water or high pressure running water. 
 
•The AD-8527 is supplied power and is turned on only 
when it is connected to a weighing instrument or the 
USB of a personal computer. 
 
 
 
 
 
1. Introduction 
This manual describes how the AD-8527 works and how to get 
the most out of it in terms of performance. Please read this 
manual completely before using the AD-8527. 
 
2. Features 
•When connected to the RS-232C interface of a weighing 
instrument and to a personal computer using USB 
simultaneously, the AD-8527 can transmit the weighing data 
that the weighing instrument outputs in real time to the personal 
computer. This enables a personal computer without COM 
ports to receive data. 
•The AD-8527 functions similar to a USB keyboard. Thus, no 
software installation such as a driver is not necessary. Once 
connected as described above, the weighing data can be 
transmitted to the personal computer. 
Note that Command transmission from the personal computer 
to the weighing instrument is not available. 
•The AD-8527 can transmit the data to any application such as 
Excel, Word and Notepad for Windows. 
•As power is supplied to the AD-8527 from the weighing 
instrument or USB, no special power source is required. 
•The AD-8527 has no data storage function. To store data 
without using a personal computer, use the AD-1688 Weighing 
Data Logger. 
Note: The AD-8527 is supplied power and is turned on only 
when it is connected to a weighing instrument or the 
USB of a personal computer.

7. Transmitting the Weighing Data 
Transmitting data from a weighing instrument to a personal 
computer. 
1. Connect the AD-8527 to the USB port of a personal 
computer and connect the AD-8527 to a weighing 
instrument using the RS-232C cable. 
Note: Use the cable appropriate to the RS-232C 
connector of the weighing instrument. 
 Power is supplied to the AD-8527 
and the standby display appears. 
 If either USB or RS-232C is not 
connected, “- - - -“ appears. 
2. Press the PRINT key of the weighing instrument to 
transmit the data to the AD-8527. 
 Then, the AD-8527 transmits the data to 
the personal computer as keyboard input 
signals. When transmitted, a buzzer sounds 
and “out” appears for about 2 seconds. 
Note: If data is not input into Excel correctly, refer to 
“10.2. If the Data Fails to be Input into Excel 
Correctly”. 
When transmitting GLP output and statistical 
results, set the weighing instrument “Data 
output pause (pU5e)” to “Pause (1.6 seconds)”. 
3. Repeat step 2 as necessary. 
4. Disconnect the weighing instrument from the AD-8527.
 
5. Disconnect the personal computer from the AD-8527.
