The CT Series RS-232 Accessory is a bidirectional interface which enables the balance
to communicate with a printer or computer that is equipped with an RS-232 serial port.
The Interface assembly is easily installed in the balance and all communication
parameters are configured using the Setup Menu (reference the CT Series Manual).
Before installing the Interface assembly, observe the following:
WARNINGWARNING
WARNING
WARNINGWARNING
To prevent damage to the balance, be certain that the power supply is
disconnected before removing the cover.
Even though the balance may have been switched OFF, voltage is present
inside the balance as long as the power supply is connected.
If the AC Adapter is being used, disconnect it.
If batteries are installed, remove them.
INSTALLATIONINSTALLATION
INSTALLATION
INSTALLATIONINSTALLATION
To install the RS-232 Interface Accessory, first remove the Pan from the balance, and turn the balance upside down.
(Do not remove Pan on CT3000L and
CT6000 Models.)
1.The bottom plate is held by four
screws, one located in each corner.
Remove the four screws and lift off
the bottom plate.
NOTE:NOTE:
NOTE: On earlier models the bot-
NOTE:NOTE:
tom plate is held by one screw located toward the center of the plate.
2.On the rear of the balance, a protec-
tive label is provided which covers
the hole for the 9-pin RS-232 connector.
Peel off the label to expose the hole.
3.Place the circuit board and connec-

tor assembly in the balance so that
the 9-pin connector fits through the
hole.
4.Fasten the assembly using the two
screws provided.
5.Slide the ribbon connector onto the
edge of the main circuit board as
shown in the diagram.
Replace the bottom plate and install
the batteries or AC Adapter. Replace the pan if it was removed.

The balance can now be interfaced with
other equipment utilizing the 9-pin connector which has been installed. The
diagram shows the pin-out and pin de-
scriptions for the connector.
The balance will not output any informa-
tion unless pin 5 (CTS) is held in an ON
state (+3 to +15 VDC). Interfaces not
utilizing the CTS handshake may tie pin
5 to pin 6 to defeat it.
NOTE:NOTE:
NOTE: This interface does not strictly

Once installation is completed, the interface parameters must be entered using the
Setup Menu (reference the CT Series Manual). When the interface is installed in the
balance, the Setup Menu will include an additional item, the Print submenu. Using the
Print submenu to enter the interface parameters includes:
• Selecting a Baud Rate
• Selecting a Data Frame Format (data bits, parity, stop bits)
• Selecting the Auto Print Interval (1-99 seconds)
• Enabling or Disabling the “Print Stable Data Only” feature
To begin, access the Setup Menu as explained in the CT Series manual, then repeatedly
press the UNITS button until “Print” is displayed. When “Print” is displayed, press the
TARE button to access the Print submenu selections. (On Legal for Trade models, the
RE-ZERO button replaces the TARE button.)
The first item displayed will be the RS-232 parameter selection. Pressing the UNITS
button repeatedly enables you to scroll through the Print submenu. Pressing the TARE
button lets you access the displayed selection.

DIRECT CONNECTION TO A PRINTERDIRECT CONNECTION TO A PRINTER
The balance can be connected directly to a printer using the RS-232 Interface. Display
data can be sent to the printer in the format shown below, using one of three methods:
• using the Auto Print feature
• using the UNITS button (balances with version 2.0 software or later)
• using an external print switch
To send data to the printer using the UNITS button, press and hold the button for at least
three seconds. The word “Print” will be displayed and the current display data will be
sent. If only one weighing unit is enabled (in the Setup Menu), the UNITS button
becomes a dedicated PRINT button and does not have to be held for three seconds.
An external print switch may be connected between pins 9 (PRINT) and 7 (GND) of the
9-pin connector. This must be a normally open switch. When the switch is closed, the
current display data will be sent.

Before using the balance, its calibration
should be checked. The balance has
been calibrated before shipment, however, calibration is influenced by factors
such as:
• Variations in the earths gravitational
field at different latitudes of the world.
• Rough handling.
• Changes in work location.
• Height above sea level.
To check the balance’s calibration, place
a known mass on the center of the platform and read the displayed weight.
If the displayed weight differs from the
known mass by more than acceptable
limits, refer to the Calibration Menu and

Linearity calibration. Span calibration resets the balance’s weighing range using two
points: zero and a calibrated mass value at or near the balance’s capacity. Linearity
calibration minimizes deviation between actual and displayed weights within the
balance’s weighing range using three points: zero, a calibrated mass value within the
balances weighing range, and a value at or near the balance’s specified capacity. The
illustration below indicates the sequence in which submenus appear on the Calibration
menu.

Before beginning calibration, make sure
calibrated masses are on hand. If you
begin calibration and realize masses are
not available, either turn the balance off, or
go through the procedure without masses.
The balance will use previously stored
calibration data. Calibration should be
performed as necessary to ensure accurate weighing. Masses required to perform the procedures are listed in the adjacent table.

Conversion factors are expressed in scientific notation and entered into the balance in three parts:
• A number between 0 and 9 to four
decimal places
• A power of 10 called the exponent.
• A least significant digit (LSD).
Use the following procedure to enter conversion factors:
1.Access the C.Unit submenu.
2.The mantissa of the current conversion factor will be displayed. This will
be a number between 0 and 9.9999

TO PREVENT DAMAGE TO THE BALANCE, BE CERTAIN THAT POWER IS
DISCONNECTED BEFORE REMOVING
THE COVER.
1.Disconnect power to the balance.
2.Remove the Platform from the balance, and turn the balance upside
down. (Do not remove Platform on
CT6000 Models.)
3.Remove batteries if installed.
4. The bottom plate is held by four
screws, one located in each corner.
Remove the four screws and lift off
the bottom plate.
5.At the rear of the balance, a protective
label is provided which covers the
hole for the 9-pin RS232 connector.
Peel off the label to expose the hole.

Cable ConnectionsCable Connections
It is recommended to use an Ohaus cable,
however, you may configure your own.
On the rear of the balance, a 9-pin subminiature “D” connector is provided for interfacing to other devices. The pinout and pin
connections are shown in the adjacent
illustration.
The balance will not output any data unless pin 5 (CTS) is held in an ON state (+3
to +15 V dc). Interfaces not utilizing the
CTS handshake may tie pin 5 to pin 6 to
defeat it.
Connect the cable from the balance to the
external device.
If communication parameters of the external device match the factory settings, the
Interface is ready for use. Refer to Printing. If not, refer to Configuring the Print
Menu to change the interface parameters.

theswitch on the balance can initate
print commands as follows:
1. Short press when only
2. Slightly extended press when
3. Longer press turns the balance
The display indicates -P- and the external device will print. Data output is in the format
shown under the P command in the RS232 Command Table.
Data output can also be initiated as follows:
1.Using the Auto Print feature.
2.Sending a print command (“P”) from a computer.
3.Using an external print switch.
When the interface is connected to a computer, two way communication between the
computer and balance is possible using the commands outlined in the RS232
