| Welcome!___1
Thank you for your JFP purchase /
This is an Instruction Manual for the AD-8118A Journal printer. The
AD-8118A is a product of years of design, development, and in-field
testing. It is designed to withstand harsh environmental conditions - and
each printer is subjected to several levels of quality control before it leaves
the factory. Every care has been taken during the manufacturing process
of this printer to ensure that it will perform accurately and reliably for
many years.
The AD-8118A Journal Printer is mainly for use with A&D's industrial scales
and electronic balances. A highly reliable printer mechanism is perfect for
industrial use, a watchdog circuit prevents malfunctioning and the AD-
8118A is built solid to protect against noise influence. Easy to operate, the
Journal Printer provides fast dependable printing.
Features
□ Dot impact printing mechanism.
□ Can print 24 columns per line.
□ Easy connection to serial input cable.
□ Small DIN size body can be mounted on panel.
□ Cumulative total function by code.
□ Calendar/clock function.
□ A lithium battery provides cumulative total and calendar back-up
without AC power for approximately 6 years.
□ 60 mm paper used for large printing capacity.

Installation
Best Conditions for Installation
Be careful when handling this unit because it is a precision electronic
device.
1) Don't install the AD-8118A in direct sunshine. Avoid places where
there are sudden temperature changes, vibrations, strong winds and
excessive moisture or dirt.
Also, keep away from conductive substances such as carbon powder.
If these substances get inside the unit errors can occur.
2) The best temperature setting is about 20°C (68°F) at 50% relative
humidity.
3) Be careful not to expose the unit to excessive noise or static electricity,
this may cause malfunctioning.
Connection of Power Supply/Ground
1) Earth the AD-8118A via the power cable to the rear terminal of your
scale or balance. Don't plug it in directly to any other equipment. Do
not use it commonly with power devices.
2) If the local AC electricity supply fluctuates by more than ±10% an AC
regulator must be used to stabilize the power supply. Do not use a
common source for the power lines.
NOTE:
Do not turn ON the power at this time. Connect the power
plug after all other connections have been made.
Connection of Serial Input
The Serial Input on the rear panel can be connected with either the RS-
232C input or the current loop input. Select the appropriate input with the
slide switch also located on the rear panel.
Direct Connection
The Serial Input can be connected with a standard serial output or current
loop on A&D Weighing Indicators.(ex. AD-4322A, AD-4323, AD-4324,AD-
4325A)
Page 8
owners-AD-81 l8A-v.3.a

Using the Optional Interface
The Serial Input can be connected with a RS-232C input or current loop
input using an RS-232C optional interface. This can be done with the FX,
FY, FR, FV, FW and AD-4316 or AD-4321. (If the option is provided with a
current loop output, it can be used as well.)
Note that these unbare equipped with outputs that can be connected to
the AD-8917, AD-8918, AD-8117 and AD-8118A externally.

The DIP switch explanations are described beginning below:
Baud rate _ Switch #1
Baud rate is the speed of transmitting data. It can be changed by the DIP
switch #1. Choose either a faster 2400bps or normal 600bps speed.
Choose 600bps to avoid errors caused by the expansion of the cable.
Data bit _ Switch #2
Data bits are the bits used to transfer one character of data; 7 bits or 8
bits are available. Even parity is performed on 7bit data.
Printing mode _ Switch #3
Dumb printing is simply having ali print formatting controlled by an
external device. All function keys and inputs are disabled except for the
FEED key.
owners-AD-8118A-v.3.a
Page 13

The Standard format results in data after the output from an A&D
industrial scale or electronic balance is internally processed and
formatted. Printing timing, cumulative total, etc. are taken. (For the input
data of the standard format, refer to "Applications," p. 21.)
Printing form _ Switch #4
Select the printing direction.
Normal character Printing direction Inverted character Printing direction
When Normal characters are selected they seem to be inverted during
printing, but the printing process is the same as the input data process.
Inverted characters selected seem to be normal, but the printing process is
the opposite of the input data process.
Status printing _ Switch #5
Changes over to enable/disable the data at minus/unstable.
Printing character Switch #6
Choose either standard character size (5x7 dots) or
enlarged (10 x 7).
Kev input _ Switch #7
Enable or disable the key inputs from the front panel.
Setting mode change Switch #8
If this DIP switch is selected the unit is in the setting mode explained below.
Function Setting Mode
Setting mode can only be accessed when DIP switch #8 is turned ON.
Then, while pressing the SET UP key, press the M+.PRT.key at the same
time. The following message is printed:

This command deletes the last added data from the
cumulative total value and then prints the message
"^CANCEL". It is unable to perform this command if
there is no cumulative total value.
This command deletes the cumulative total value and
then prints the message "*CLEAR". It is unable to
perform this command if there is no cumulative total
value.
Time printing is disabled while this input is ON. Once
OFF, the time printing is preformed once more on the
next printing time. In cumulative total printing, time
printing is preformed regardless of the input.
This output is turned ON when the data buffer exceeds
75 lines.
This output is turned ON when the unit is printing.
Control inputs are not accepted during this time.
Therefore, enter the control input when this output is
OFF.
