1.2 Overview
The Tracer AV is a single-channel digital weight indicator comprised of three components:
• The Tracer AV houses the AC power supply and CPU board. There are external DB-9 connectors for a PC connection,
two remote display connections, two remote keypad connections, and a load cell connection (See Figure 2-3 on page 5).
• RD-1 remote display, an .8'', six-digit, seven-segment LED display or RD-2 remote display, an .8'', six-digit, seven-
segment LCD display.
• The RK-1 keypad (See Figure 1-1 on page 2) has two keys which are used to zero the scale and to toggle between a
primary and secondary unit of measure in the normal mode of operation. These keys have a secondary function for the
setup mode.
The Tracer AV features include:
• Four-wire load cell connections; remote sense connections are not provided
• The electronic data processing (EDP) port is full duplex; RS-232 communications at up to 38400 bps. The EDP port is
accessed through the COMM connection
• The serial port connects to the remote displays. The output is RS-232 and will drive two remote displays
• Digital inputs are defaulted for RK-1 functionality
• Setpoints values will cause the display to flash when a specified weight value is exceeded
• Available for 115 VAC and 230 VAC

1.3 Operating Modes
The Tracer AV has three modes of operation.
Normal (Primary) mode
Normal mode is the default mode of the Tracer AV. The indicator displays gross or net weights as required, using the LCD/
LED annunciators described in Section 1.5 on page 3 to indicate scale status and the type of weight value displayed. Once
configuration is complete and a legal seal is affixed, this is the primary mode in which the Tracer AV can operate.
Setup mode
Most of the procedures described in this manual require the Tracer AV to be in setup mode, including configuration and
calibration.
To enter setup mode, remove the setup switch access screw on the Tracer AV (See Figure 2-3 on page 5). Once the screw
is removed, use a small screwdriver or pen tip to press the setup switch. The display changes to show the word DEFCAL.
Test mode
Test mode provides a number of diagnostic functions for the Tracer AV. Like setup mode, test mode is entered using the
setup switch. See Section 6.7 on page 38 for more information.
Test mode is intended for factory use only.
1.4 Display and Keypad
Figure 1-1 shows the Tracer AV LCD display with annunciators and keypad. In setup mode, the keys are used to navigate
through menus, select digits within numeric values and increment/decrement values. See Section 3.1.2 on page 12 for
information about using the front panel keys in setup mode.

1.5 LCD/LED Annunciators
The Tracer AV display uses a set of six LCD/LED annunciators to provide additional information about the value being
displayed:
•Gross and Net annunciators are lit to show whether the displayed weight is a gross or net weight.
•Center of Zero ( ): Gross weight is within 0.25 graduations of zero. This annunciator lights when the scale is
zeroed.
•Standstill ( ): Scale is at standstill or within the specified motion band. Some operations, including tare function,
can only be done when the standstill symbol is shown.
•lb and kg annunciators indicate the units associated with the displayed value: lb = pounds, kg = kilograms.

shipping carton should contain the Tracer AV enclosure, remote display, remote keypad, this manual, two cables and a power
cord. If any parts were damaged in shipment, notify Rice Lake Weighing Systems and the shipper immediately.
2.2 Enclosure Security/Disassembly
After an NTEP inspector has examined the unit, he/she will install security cables pictured in Figure 2-1 and Figure 2-2 on
page 5. These cables prevent the Tracer AV from being tampered with by an unauthorized individual. If these cables are
removed, NTEP certification will become void.
If the Tracer AV enclosure must be opened by an authorized technician, ensure power is disconnected, then place it on an anti-
static work mat. Cut tamper-proof cables, remove screws and remove the enclosure’s top cover. An NTEP inspector will have to
examine the unit and attach new security cables.

2.3.3 Serial Communications
The pinned DB-9 connector marked as COMM is connected to EDP port J3. It is bi-directional communication to be used for a
PC connection.
There are two socketed DB-9 connectors for remote displays which are connected to the serial port J4. The remote display’s
DC power and communications are run in the same three-conductor cable. The serial port data is transmitted on the 20 mA pins
to the remote displays.
2.3.4 Digital I/O
Digital inputs can be set to provide several indicator functions, including all keypad functions. In the Tracer AV, these inputs are
set to Zero and Units for the remote keypad. The inputs are active (on) with low voltage (0 VDC) and can be driven by TTL or 5V
logic without additional hardware. LEDs on the CPU board light when digital inputs are active.
Digital outputs are typically used to control relays that drive other equipment. In the Tracer AV, the setpoint value will cause the
display to flash. Outputs are designed to sink not source, switching current. Each output is a normally open connector circuit,
capable of sinking 250 mA when active. Digital outputs are wired to switch relays when the digital output is active (low, 0 VDC)
with reference to 5 VDC supply. LEDs on the CPU board light when the digital outputs are active.

2.4 Board Removal
If the Tracer AV CPU board must be removed, use the following procedure:
Use a wrist strap to ground yourself and protect components from electrostatic discharge (ESD) when working
inside the Tracer AV enclosure.
This unit uses line fusing which could create an electric shock hazard. Procedures requiring work inside the
Tracer AV enclosure must be performed by qualified service personnel only.
The supply cord serves as the main power disconnect for the Tracer AV. The power outlet must be installed near
the unit and be easily accessible.
1. Disconnect power to the Tracer AV.
2. Cut security cable (if installed) and remove screws.
3. Remove the top cover.
4. Disconnect power supply cable from connector J7 on the Tracer AV CPU board.
5. Unplug connectors J1 (load cell cable), J2 (digital inputs), J3 (EDP), J4 (serial), J6 (digital outputs), and J2 (display).
See Figure 2-4 on page 6 for connector locations.
6. Remove the five screws from the CPU board, then lift the board out of the enclosure.
To replace the CPU board, reverse the above procedure.

3.0 Configuration
To configure the Tracer AV, it must be placed in setup mode. Setup mode is initiated by pressing the setup switch on the Tracer
AV (see Figure 2-3 on page 5).
When the Tracer AV is placed in setup mode, the word CONFIG is shown on the display. The CONFIG menu is the first of 7 main
menus used to configure the Tracer AV. Detailed descriptions of these menus are given in Section 3.2 on page 14. When
configuration is complete, continue pressing the (Units) key to exit setup mode.
3.1 Configuration Methods
The Tracer AV can be configured by using the Zero and Units keys to navigate through a series of configuration menus or by
sending commands or configuration data to the EDP port. Configuration using the menus is described in Section 3.1.2.
Configuration using the EDP port can be accomplished using either the EDP command set described in Section 5.0 on
page 27.
3.1.1 EDP Command Configuration
The EDP command set can be used to configure the Tracer AV using a personal computer, terminal, or remote keyboard. EDP
command configuration sends commands to the Tracer AV EDP port. EDP commands can be sent using any external device
capable of sending ASCII characters over a serial connection.
EDP commands duplicate the functions available using the Tracer AV front panel and provide some functions not otherwise
available. EDP commands can be used to simulate pressing front panel keys, to configure the Tracer AV, or to dump lists of
parameter settings. See Section 5.0 on page 27 for more information about using the EDP command set.
3.1.2 Front Panel Configuration
The Tracer AV can be configured using a series of menus viewed on the RD-1 display when the Tracer AV is in setup mode.
