AD-8920 REMOTE DISPLAY INSTRUCTION MANUAL
（日本語の取扱説明書は反対面をご覧ください。）
1. Introduction
The AD-8920 is a remote display that uses vacuum fluorescent display technology. It displays the weighing
data transmitted by an A&D manufactured weighing instrument using RS-232C or current loop. Applicable
weighing instruments (electronic balances/platform scales) are listed below. When the output connector of the
weighing instrument is of the DIN type, an optional DIN conversion cable is required.

2. Preparation
2-1. Setting the weighing instrument
Table 2 List of instrument settings
Item Setting
Description
Data output mode Stream mode
Outputs the weighing data continuously.
Baud rate
2400bps or 600bps
AD-8920 recognizes the baud rate automatically.
Length, Parity bit
7 bits-even, 7 bits-odd, or 8 bits-none
AD-8920 functions correctly with any one of those listed.
Stop bits
1 bit or 2 bits
AD-8920 functions correctly with either one.
Terminator
AD-8920 functions correctly with either one.
Data format
A&D standard format
CTS control
No control of CTS, RTS
Output (hardware) RS-232C or current loop
AD-8920 recognizes the output mode automatically.
Note) The available items depend on the weighing instrument. (An item is not available when the setting is fixed.)
For a detailed description of the settings, refer to the instruction manual of each weighing instrument.
2-2. Connecting the AD-8920
1.Confirm that the AC adapter is of the correct type. 2.Refer to the Table1 shown above to connect the
communication cable correctly. Use the OP-01 DIN conversion cable when the output connector on the
weighing instrument is of the DIN type. 3.Refer to the connecting diagram shown above to connect the
AD-8920 to the weighing instrument by the communication cable.
