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.

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.
