SITE PREPARATION REQUIREMENTS
The 204 Weight Indicator is a precision weight indicating instrument. As with any precision
instrument, it requires an acceptable environment to operate at its peak performance and
reliability. This section is provided to assist you in obtaining such an environment.
Electrical Power
The 204 indicator has been designed to operate from a 115 VAC 50/60 Hz (optional 230 VAC
50/60 Hz) AC adapter. Note that an optional AC adapter is required for operation at 230 VAC.
CAUTION! - To avoid electrical hazard and possible damage to the indicator,
DO NOT, under any circumstance, cut, remove, alter, or in any way bypass the
power cord grounding prong.
On models requiring 230 VAC power, it is the responsibility of the customer to have a
qualified electrician install the proper power cord plug which conforms to national electrical
codes and local codes and ordinances.
The power outlet for the indicator should be on a separate circuit from the distribution panel.
This circuit should be dedicated to the exclusive use of the indicator. The wiring should
conform to national and local electrical codes and ordinances and should be approved by the
local inspector to assure compliance.
To prevent electrical noise interference, make certain all other wall outlets for use with air
conditioning and heating equipment, lighting or other equipment with heavily inductive loads,
such as welders, motors and solenoids are on circuits separate from the indicator. Many of
these disturbances originate within the building itself and can seriously affect the operation of
the instrument. These sources of disturbances must be identified and steps must be taken to
prevent possible adverse effects on the instrument. Examples of available alternatives include
isolation transformers, power regulators, uninterruptible power supplies, or simple line filters.
2
PRECAUTIONS
In general, the 204 indicator will perform well
within a temperature range of
14 to 104 °F (-10 to +40 °C ).
In order to keep cooling requirements to a
minimum, the indicator should be placed out
of direct sunlight and to provide adequate air
circulation, keep the area around the indicator
clear.
Make certain the indicator is not directly in
front of a heating or cooling vent. Such a
location will subject the indicator to sudden
temperature changes which may result in
unstable weight readings.
Insure that the indicator has good, clean AC
power and is properly grounded.
In areas subject to lightning strikes, additional
protection to minimize lightning damage, such
as surge suppressors, should be installed.
INSTALLATION
Before beginning installation of your 204 weight indicator, make certain that it has been
received in good condition. Carefully remove the indicator from the shipping carton and
inspect it for any evidence of damage (such as exterior dents and scratches) that may have
taken place during shipment. Keep the carton and packing material for return shipment if it
should become necessary. It is the responsibility of the purchaser to file all claims for any
damages or loss incurred during transit.
Should your 204 come already installed on a scale, the following information describing the
installation of the indicator does not apply to you.
Mounting
Begin the installation by deciding where the indicator is to be mounted. The 204 indicator may
come mounted on a column or you may choose to mount it on a desktop or wall. Refer to
Figure No. 1 for illustrations of the mounting bracket. Two (2) holes are located in the
mounting bracket for attachment to the wall. This bracket may be removed or left in place for
desktop use.
Regardless of how and where you mount your 204, it should be in a safe area where it will not
be in the way of normal traffic. The location chosen should be free of temperature extremes
and water. It should be in a location where the display is easily viewed and is not subject to
direct sunlight. The indicator should be mounted such that it is within easy reach of the
operator. If wall mounted, make certain that the structure and mounting bolts are of sufficient
strength to support the 204. The mounting bracket should be securely fastened to the wall or
column top so that it cannot break loose from the mounting surface. After the 204 has been
mounted, it may be connected to the plug-in power supply or the batteries may be installed.

Interconnections
All Input, Output and power connections to the 204 are made at the rear panel of the indicator.
Connections for the Load Cell input and the RS-232 Serial I/0 are all made via 9 pin "D"
shaped subminiature connectors. The 12VDC 300 mA wall plug-in UL/CSA listed power
supply is connected using a power jack. Figure No. 2 illustrates the layout of the rear
connector panel.
Power Supply
To apply power to the 204 using the power supply, connect the power cable’s connector into
the power jack on the back of the indicator and then connect the 12 VDC, 300 mA power
adapter into the proper electrical outlet. The 204 is now ready for operation.
Batteries
The 204 can use 6 "C" size Alkaline, Ni-Cad
or NiMH batteries (not included). If you wish
to operate the 204 from batteries, you must
first obtain and install batteries before
operations can begin. The batteries are
contained in a battery holder inside the
indicator. Access is via a removable panel
on the back of the indicator.

After placing all 6 batteries in the holder, replace the panel on the back of the indicator (slide
the tab in the slot on the rear panel) and install the thumb screw. Make sure the wall plug-in
power supply is unplugged, then turn the indicator over (display facing up) and press the
ON|OFF key. If the display turns on, the batteries have been installed correctly. If not, remove
the panel and check for one or more improperly positioned batteries..
The 204 indicator can be operated from a power supply or from Alkaline, NiCad or NiMH batteries. All six (6) batteries must be of the same type. They
must all be Alkaline, all Ni-Cad or all NiMH. DO NOT mix Alkaline and Ni-Cad or
NiMH batteries. The power supply is also used to recharge the batteries, when
the 204 is operated from Ni-Cad or NiMH batteries. DO NOT connect a power
supply to the scale if using Alkaline batteries.
Low Battery Indicator
When the batteries are near the point they need to be replaced (Alkalines) or recharged
(NiCad or NiMH), a low battery annunciator on the display will turn on. (See Figure No. 7). If
the battery voltage drops too low for accurate weighing, the 204 will automatically shut off and
you will be unable to turn it back on.
If using Alkaline batteries when the low battery annunciator turns on, turn the 204 off, remove
the old batteries and replace with new ones. Follow the same procedure for installing batteries
when battery replacement becomes necessary.
If using NiCad or NiMH (and the QL&$G setup option is enabled, set to "1"), plug the power
supply into the indicator and then into the proper electrical wall outlet. The 204 will begin
charging the batteries.

INSTALLATION, Cont.
Battery Status
If batteries are used, the indicator will show the battery status on power up. The display will
show EDWWU\ then change to ò << ò, where YY indicates the remaining battery voltage
expressed as a percentage (%) of the total battery voltage.
Battery Charging
To recharge the Ni-Cad or NiMH batteries, the power supply must be connected to a AC power
outlet and plugged into the indicator. It will take approximately 15 hours to fully recharge the
batteries in the scale. While the batteries are charging the 204 can still be operated. Note that
charging the batteries for more than 15 hours will not damage them.
When the 204 is to be turned off, pressing the ON/OFF key once will display “dashes" scrolling
across the display indicating the batteries are being charged. Pressing the ON/OFF key
again, will display 2)) and turn the 204 off. If the power supply is disconnected before the 15
hours, the indicator will continue to charge the batteries when the power supply is plugged
back in.
NOTE: When the 204 is turned off, the indicator is NOT charging the batteries.
Load Cell Connection
The load cell cable connects to the 204 via a 9-pin "D" connector on the rear panel of the
indicator. Figure No. 4 shows the pin identification for the load cell connector. Make certain
that the pins are correctly identified before soldering a wire to them. Use the connector
retaining screws to hold the load cell cable connector securely to the rear panel.

SERIAL DATA FORMATS
Weight-On-Demand
If the Printer Continuous output was not selected, &2QW (0=NO) during setup and calibration
of the indicator, and the 204 is connected to a computer, it will transmit a single set of weight
data each time the computer sends an ENQ (hex 05) or a SMA weight request (W). This is
known as Weight-On-Demand. Eamples and explanation of the data format transmitted are
shown below.
Continuous Output
If the Printer Continuous output was selected &2QW (1=YES) during setup and calibration,
the 204 will transmit weight data continuously. If connected to a remote display, the display
will continuously show weight data. An example and explanation of the data format
transmitted is shown below.
Weight-On-Demand And Continuous Output Data Format
The data format transmitted for both Weight-On-Demand and Continuous Output will be
GROSS weight only. The weight data always includes the units of measure. An example of
the data output (with and without a decimal point) is shown below:

The low battery annunciator is used with the battery operation. It will turn ON to indicate that
the batteries will soon need to be replaced (if using Alkalines) or recharged (if using NiCad or
NiMH). No change in operation will occur until just before the battery voltage drops to a level
where operation is affected. At this level, the indicator will automatically turn itself off.
NET
The NET annunciator is turned on to show that the weight displayed is the net weight. Net
weight is determined by subtracting the stored tare weight from the gross weight. The tare
weight, is usually the weight of the empty container. Note that the NET annunciator is only
active when a tare weight value is stored.
GROSS
The GROSS annunciator is turned on to show that the weight displayed is the gross weight.
Gross weight will be displayed when no tare weight value is stored.
TARE
The TARE annunciator is turned on to show that the indicator is in a weight mode in which a
known tare (container) weight value is stored.
