AUTO-FORMAT FEATURE
The RD3 serial interface can automatically select the serial input protocol from the serial output
of an indicator in one of the following serial formats:
SMA, Cardinal SB400, Numbers, Rice Lake IQ355, ANDFV,
WI110, Toledo Short, and Toledo Long
The interface will automatically detect baud rates between 2400 and 19200 baud with the
following settings:
Baud rate: 2400 to 19200 (7 or 8 Data Bits)
Character format: all standard ASCII characters
SITE PREPARATION
Electrical Power
The RD3 display has been designed to operate from 100 to 240V AC at 47/63 Hz.
CAUTION! To avoid electrical hazards and possible damage to the display,
DO NOT, under any circumstance, cut, remove, alter, or in any way bypass the
power cord-grounding prong.
•The power for the display should be on a separate circuit from the distribution panel. This
circuit should be dedicated to the exclusive use of the display.
•The wiring should conform to national and local electrical codes and ordinances and should
be approved by the local inspector to ensure compliance.
•For permanently connected equipment, a readily accessible disconnect device must be
provided external to the equipment.
•For pluggable equipment, the socket outlet shall be installed near the equipment and shall
be easily accessible
•It is the responsibility of the customer to have a qualified electrician install the proper
service disconnect that conforms to national electrical codes and local codes and
ordinances.
Electrical Noise Interference
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 display. Many of
these disturbances originate within the building itself and can seriously affect the operation of
the display. These sources of disturbances must be identified and steps must be taken to
prevent possible adverse effects on the display. Examples of available alternatives include
isolation transformers, power regulators, uninterruptible power supplies, or simple line filters.

SINGLE AND MULTIPLE DISPLAY
The RD3 display has been designed to echo received characters (from a single weight
indicator) to other RD3 displays allowing the same weight data to be shown on multiple
displays. Typical applications might consist of back-to-back displays or displays placed at each
end of the scale.
The figures below are typical installations consisting of a single indicator to a single display
(Figure No. 1), a single indicator to two displays (Figure No. 2), and a single indicator with two
or more displays (Figure No. 3).

INSTALLATION
Unpacking
Before beginning the installation of your RD3 Display, make certain that it has been
received in good condition. Carefully remove it from the shipping carton and inspect it for
any evidence of damage (such as exterior dents or 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 losses incurred during transit.
Mounting the RD3 Display
The RD3 Display includes a two-piece bracket that is used to mount it on a wall or other flat
vertical surface using a quick-detach bracket. Note that the Display Bracket is installed on the
RD3 at the factory.
Figure No. 4
Installing the Wall Bracket
Refer to Figure No. 4 for a layout of the wall bracket mounting holes.
1. Make certain the mounting surface is strong enough to support the display and that the
mounting location is where the display can easily be viewed.
2. Position the wall bracket with the wider end at the top, and using the wall bracket as a
template, mark the mounting hole locations and drill the holes.
3. Install the screws through the wall bracket and securely tighten.
4. Insert the narrow end of the display bracket into the wide end of the mounted wall bracket
and pull it down into place.

Cable Installation
1. Remove the 12 screws securing the front panel to the main housing.
2. Referring to Figure No. 5, choose a gland connector for the serial cable, loosen it, and
remove the rubber plug.
3. Slip the single cable through the gland connector and into the enclosure.
4. Remove approximately 3 inches of the outer insulation jacket from the cable then remove
1/4 inch of insulation from each of the wires.
5. Referring to the labels on the circuit board) for terminal connections, connect each of the
wires to terminal block P4. Refer to Figure No. 9 for the terminal block location
6. To terminate a wire, use a small flat-blade screwdriver and press down on the release bar
for the terminal. Insert the wire into the terminal opening. Remove the screwdriver,
allowing the release bar to return to its original position, locking the wire in place.
7. Repeat the procedure until all wires are in place.
8. After all, terminations have been made, remove any excess cable from the enclosure, and
securely tighten the cable gland connector. Finger-tighten only! DO NOT USE TOOLS!

SETUP AND CONFIGURATION
The RD3 display has been pre-configured at the factory and should not require configuration
for use in most applications. If the factory settings do not meet the requirements of your
application, the following describes the steps to configure the display.
The setup mode switch is located on the back of the
display board. You may gain access to it by removing the
12 screws securing the front panel to the rear housing.
Refer to Figure No. 10, for the location of the SETUP
switch.
•When a prompt is displayed, press the SETUP switch
to retain the current value and proceed to the next
prompt.
•To change a setting, press the Up Arrow switch to scroll through and select a new
value.
•Press the Left Arrow switch to "back up" to the previous prompt.
Enter Setup Mode
1. With the front panel removed and the display ON, press and release the SETUP switch.
2. The display will change to show SETUP.
3. Press the SETUP switch again.
4. The display will change to show type=_ and the current value.
tyPE=(Serial Format)
This option allows you to manually select a serial format and override the Auto-format
feature by setting type= to a number listed below. Note that the factory default value is 0
(Auto-format is enabled).
If the value displayed is acceptable, press the SETUP switch again. Otherwise, press the
Up Arrow switch to scroll through and select a new value andthen press the SETUP
switch to save it and proceed to the next prompt. Values from 0 to 8 may be selected.

This option allows you to manually select a baud rate and override the Auto-baud feature by
setting baud= to a number listed below. Note that the factory default value is 0 (Auto-baud
is enabled).
If the value displayed is acceptable, press the SETUP switch again. Otherwise, press the
Up Arrow switch to scroll through and select a new value and then press the SETUP

This option allows you to manually select 7 or 8 data bits for the serial port data format. Note
that if Auto-format is enabled (type=0), the data=setting is ignored.
If the value displayed is acceptable, press the SETUP switch again. Otherwise, press the
Up Arrow switch to toggle to the other value and then press the SETUP switch to save it.

RE-INSTALLING THE FRONT PANEL
After all the terminations have been made, changes to setup have been completed, and the
display brightness set to the desired level, it’s time to re-install the front panel.
1. Gently pull any excess cable (AC power and serial) from the enclosure.
2. Securely tighten the cable gland connectors.
•Do not over-tighten the connectors but make certain they are snug.
•DO NOT USE TOOLS! Finger-tighten only!
