RD2 Series
2
AUTO-FORMAT FEATURE
The RD2 serial interface can auto-format most serial protocols (automatically selects input
protocol). The interface auto detects baud rates between 2400 and 38400 baud with the
following settings:
Baud rate
2400 to 38400
Data bits
7 or 8
Character format
all standard ASCII characters
MULTIPLE DISPLAYS
The RD2 display has been designed to echo received characters (from a single weight
indicator) to other RD2 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.
SITE PREPARATION
Electrical Power
The RD2 display has been designed to operate from 94 to 264 VAC at 47/63 Hz. Note that a
special order is not required for operation at 230 VAC.
WARNING! To avoid electrical hazard 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 assure 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.
