1. INTRODUCTION
The AD-8922A is a remote controller. Read this manual completely before using the AD-8922A in orderto ensure a sufficient understanding for proper use.

1.1. Outline
The AD-8922A is connected to an A&D manufactured weighing instrument, using the RS-232C serialinterface.
 Displays the weighing data transmitted by the weighing instrument.
 Key operations remotely control the weighing instrument.
(Entering the function setting mode of the weighing instrument is not available. Available operations
depend on the weighing instrument used. See Table 2 in "1.2. Applicable Instruments".)
 The data the AD-8922A receives can be output, using the RS-232C serial interface. So, external
devices such as a personal computer or a printer can be connected to the AD-8922A.
 Can be panel-mounted.
 Various options such as BCD output, comparator output, current loop input and analog output areavailable. For details, refer to "9. OPTIONS" and the following relevant chapters.
 When connected to the AD-4212C/D/F, the AD-8922A can change the response characteristic, adjust
the sensitivity of the AD-4212C/D/F using the external mass, and both instruments can share power.
(Power can be supplied to both instruments by plugging the AC adapter into either the AD-4212C/D /For the AD-8922A. For details, refer to "3.3. Turning the Power On".)5

1.3. Compliance
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 to comply with the limits of Class A digital devices pursuant to Part
15 of FCC rules. These rules are designed to provide reasonable protection against interference whenequipment 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 his own
expense, whatever measures are necessary to eliminate the interference.
(FCC = Federal Communications Commission in the U.S.A.)7

2. DESCRIPTION OF EACH PART

124. FUNCTION SETTINGS
The function settings specify the parameters for the AD-8922A performance. These parameters stored,even if the AC adapter is removed, are maintained in non-volatile memory.
The function menu consists of two layers. The first layer is the “Class” and the second layer is the “Item”.
Each item is selected by the SAMPLE key. The parameter of the selected item is changed by the
RE-ZERO key. Finally, the parameter is stored and is enabled by the PRINT key.

ExampleThis example sets “9600 bps” for “Baud rate” and “8 bits NONE” for “Data bits, parity bit”.

•
The [] displayremains and no weighing

•••
The display flickers.

Cause and remedy
The communications settings of the AD-8922A and the weighing
instrument are not the same.
Check the settings.
The weighing instrument data format is incorrect.
Set the data format to A&D standard format. Also check whether or
not data other than weighing data is output.
Is the weighing instrument in the stream mode?
Only the stream mode displays the weighing data continuously. Other
modes display the data only when received. When the hold display is
selected in the AD-8922A function setting, the previous data received
is displayed until the next data is received.
Are the communications settings correct?
Is the cable correct?
Electrical noises may affect the display.
Using the grounding terminal located on the rear of the AD-8922A,
ground the AD-8922A.

Outputs the weighing data received from the weighing instrument using the RS-232C serial interface,in BCD format. The compatible instruments mentioned in “3.3. Turning the Power On” can share powerwith the weighing instrument.
 AD-8922A-04 Comparator output
Compares the weighing data received from the weighing instrument using the RS-232C serial interface
with the upper or lower limit value and contact-outputs the results.
When connected to the AD-4212C, the both instruments can share power.
Note: Power cannot be shared with the weighing instrument. Plug the AC adapters into both
the weighing instrument and the AD-8922A.
 AD-8922A-05 Current loop input
Receives the current loop output from the weighing instrument and displays the weighing data.
The weighing data received can be output using the RS-232C serial interface.
 AD-8922A-06 Analog output
Converts the specified digits of the weighing data received from the weighing instrument, using the
RS-232C serial interface, into voltage and outputs the value.
Note: Power cannot be shared with the weighing instrument. Plug the AC adapters into both
the weighing instrument and the AD-8922A.

9.1. Confirming the AD-8922A Software Version
Before installing an option, confirm the AD-8922A software version.
The software version is displayed as " x.xx" for approx. 1 second before entering the function setting mode.

21

9.2. Installing the Option
Install the option as shown below. The installation procedure is the same for all the options.
1. Disconnect the AC adapter.

2. Remove the two screws and pull out the RS-232C board
provided as standard as shown in the illustration.

3. Insert the option board, along the guides on the left and right sides.

4. Using the two screws removed in step 2, fasten the option board.

2210. BCD OUTPUT (AD-8922A-01)
Outputs the weighing data received from the weighing instrument in BCD format, along with the polarity(+/-) and the data status (stable/unstable and over/under).
Using the STROBE signal, the data can be read easily. The AD-8922A-01 can set the input terminal
function to either the BUSY or the RE-ZERO input function by selecting that function. When set to the
RE-ZERO input function, the AD-8922A transmits the RE-ZERO command to the weighing instrument,setting the weighing value to zero. BUSY input enables the data to be held or prevents data refreshing
during the reading operation.
The logic of data, status and strobe can be switched in the function setting.
Note: When the AD-8922A-01 is installed, the RS-232C serial interface cannot be used.
The compatible instruments mentioned in “3.3. Turning the Power On” can share powerwith the weighing instrument.
For details about the RE-ZERO function of the applicable weighing instruments, refer to
RE-ZERO of Table 2 in "1.2. Applicable Instruments".

To use the comparator output, perform the following four steps.
1. Connect the peripheral to the AD-8922A-04 DIN connector.
2. Set the “Comparator ()” of the AD-8922A function setting. For details, see “4. FUNCTION
SETTINGS”.
3. Set the upper and lower limit values. For details, see “11.3. Setting the Upper and Lower Limit Values”.
4. When the weighing data is received, the comparison results will be output.
5. When the weighing data is equal to or less than the upper limit value, and equal to or greater than thelower limit value, the OK comparator will be output.

 Using the stored upper and lower limit values, comparison can be performed easily. To recall the stored
values, press and hold the ON:OFF key and press the MODE key.

Storing the upper and lower limit values

To store new upper and lower limit values, recall the stored data ("" to "") and change them.

1. While pressing and holding the ON:OFF key, press the RE-ZERO key to enter the confirmation
mode. The upper limit value data (Comparator number and the upper limit mass (blinking)) of thecomparator number that was selected last.

Only the stored comparator numbers are displayed.
4. Press the PRINT key to confirm the selection and return to the weighing data display with theselected upper and lower limit values ready for use (In the example shown below, the values of "".)Note: When no operation is performed in step 4 (after a few seconds of inactivity), the AD-8922A
selects the value currently displayed and returns to the weighing data display
automatically.
To cancel the operation, press the CAL key.
