The Model 370 and Model 375 come standard with a six digit, 7-segment bright green LED
display. The Model 370 and Model 375 will display alphanumeric data, but due to the nature of 7­segment LED and the limitation of six digits, some information is abbreviated.

The display also has 11 annunciators to show weight and status information. The SP1, SP2, and
SP3 annunciators are red, green, and yellow. Also there is an annunciator for a third unit under
kg. Place the third unit label above the third Annunciator (refer to Figure 1-6). See page 24 for
third unit setup.

All segments and annunciators are illuminated for a brief display test upon power up. The current
gross weight is then displayed in default units.

REMOTE DISPLAY CONNECTIONS

It is possible to connect a Model 370/375 to another 300 Series or 60 Series indicator and ha ve
the remote indicator display a copy of the master indicator or customize the display of the remote
(slave) indicator. The remote (slave) indicator’s keypad will operate the master indicator. Refer to
page 55 to configure the master and remote (slave) displays. There are several different
configurations for Master to remote (slave) indicator connection and setup. Refer to Table 1-3 for
comm port connections.

Supply Voltage Jumper (E6)

This allows for a choice in scanner power supply pins and to minimize modifications to a cable or
connector.

Comm port 1 has two pins on the DB 9 connector which provide + 5 volts to supply power to a
scanner. The jumpers located on E6 of the main board will reroute the power (+ 5 volt) to either
pin 9 or pin 4 depending on jumper orientation.

Pin 9 (Default) Pin 4

The power (+ 5 volt) and remote key pins are switched. Refer to Figure 1-8 for the jumper
location on the main board. Refer to the Barcode Scanner manual for the power pin location.

Chapter 2: O

This chapter will provide detailed instructions on installing each option. Additional hardware may
be needed for the Model 370/375 depending on which options you will be installing.

Also this chapter provides instructions on how to configure all Model 370 / 375 options. This
includes setup mode parameters, connections, calibration and testing.

PTION INSTALLATION

CCoommmmuunniiccaattiioonn

RS-485 NETWORKING

The module converts the standard RS-232 communication on comm port 1 to RS-485. However
the advantage of using the RS-485 module, aside from the ability to transmit over long distances,
is the ability to network multiple indicators or parts counters using the same communication wires.
When networking indicators or parts counter, it is necessary to set up a network address for each
scale. The network module itself does not require addressing, rather each indicator or pa rts
counter must be enabled for network addressing in the setup mode. Refer to page 26 for details
on the RS-485 enable parameter (P250) and the network address parameter (P251).

Installation Instructions

1. DISCONNECT POWER! UNPLUG THE MODEL 370/375 TO INSURE DAMAGE WILL NOT
OCCUR DURING OPTION INSTALLATION.

2. Remove the six 8 mm screws (size) from the bottom plate. Separate the top enclosure from
the bottom plate.

3. Remove the IC chip and white jumper from the U4 socket on the main board.

4. Snap in the plastic spacers into the three mounting holes surrounding the U4 socket. Refer
to Figure 2-1.

5. Gently press the option board into the socket and make sure the board snaps onto the
standoffs.

6. Reinstall the enclosure bottom plate.

Figure 2-1: RS-485 / 20 mA Option Installation

RS-485 Connections (Comm Port 1)

The Model 370/375 will be connected to a peripheral via the DB 9 connector on comm port 1.
Refer to Table 2-1 for wiring connections.

1 No connection
2 TX (B+)
3 TX (A-)

5 ISO ground

7 RX (A-)
8 RX (B+)
9 VCC

Half Duplex (2-wire)

Installing jumpers 1, 2 and 4 on the RS-485 option board electrically connects pin RX B(+) to pin
TX B(+), and pin RX A(-) to pin TX A(-) on the option board. This effectively provides two + and
two - pin connections, enabling easy connection of network lines in parallel from device to d evice
without having to position two wires into the same lever socket. A B(+) line from each device on
the network should be connected in parallel to the next device on the network. This is also true for
all A(-) lines.

The units inside the two end-points of the network loop will utilize both A(-) pin connections and
both B(+) pin connections. The units at the end-points of the network will utilize only one A(-) pin
connection and one B (+) pin connection.

Full Duplex (4-wire)

Removing jumpers 1, 2 and 4 on the RS-485 option board requires that the transmit and receive
lines be wired independently of one another. The RX B(+) and RX A(-) receive lines must be
wired in parallel to the next device's RX B(+) and RX A(-) receive lines and the TX B(+) and TX A
(-) transmit lines must be wired in parallel to the next device's TX B(+) and TX A(-) transmit lines.

8

In order to connect network lines in parallel from device to device it is necessary to position two
wires into the same lever socket. This requires that the wire used to build the network be 24 AWG
or smaller to allow both wires to fit into the same lever socket.

Both Half Duplex and Full Duplex

The network boards on both end-points should install jumper 3 on the RS-485 option board to
engage the 120 W termination resistor (R8). The boards between the two en d-points should
remove jumper 3 on the RS-485 option board.

The isolated ground (ISO GND) should be connected in parallel from unit to unit. A shielded
twisted two pair cable is recommended throughout the network.

20 MA CURRENT LOOP OPTION

This option will convert the comm port 1 to a 20 mA current loop instead of an RS-232. This is a
digital communication signal and should not be confused with a 4 to 20-mA (or 0-20 mA), which
are analog output signals. The intended use is primarily printers and scoreboard displays.

This option will mount into the socket for the comm port RS-232 chip on the main board. This
option will exclude the use of the RS-485 option board. (I.e. only the RS-485 OR the 20 mA
option can be installed into a Model 370/375).

Installation Instructions

1. DISCONNECT POWER! UNPLUG THE MODEL 370/375 TO INSURE DAMAGE WILL

NOT OCCUR DURING OPTION INSTALLATION.

2. Remove the six 8 mm screws (size) from the bottom plate. Separate the top enclosure

from the bottom plate.

3. Remove U4 and the white jumper from the socket of the main board.

4. Snap in the plastic spacers into the three mounting holes surrounding the U4 socket.

Refer to Figure 2-1.

5. Gently press the option board into the socket and make sure the board snaps onto the

standoffs.

6. Reinstall the enclosure bottom plate.

BI-Directional

Both the transmit output and the receive input of the Model 370/375 are available as 20 mA
signals. None of the handshake signals are supported for the 20-mA current loop operation.

Baud

Only baud rates of 9600 baud and less are supported.

Active/Passive

The Tx output may be used as an active or passive output from the Model 370/375. Either active
or passive is chosen depending upon which terminals are used for the connections. In active
mode the Model 370/375 supplies the current. In passive mode, the external device supplies the
current. The Rx input is available in passive mode only.

Isolation

The input and output are electrically isolated from the main board as well as earth ground and
each other, for both passive and active modes of operation. Isolation is a minimum of 1000v.

Max Voltage

Active mode Tx current loop provides a driving voltage of 12v. This will allow 20 mA current flow
with up to a 600 ohm load. Passive mode will work with an external driving voltage of up to 50v.

Connections

The field connections to the 20 mA circuitry will be made at the 9 pin 'D' connector on the rear of
the Model 370/375.

Cable

The length for the current loop is 1000 ft. maximum. This is for the entire loop, not from device to
device. Example: 1 transmitter and 1 receiver can have a maximum of 500 ft. of 2 conductor
cable between them.

10

Connected Devices

While 20 mA current loops can allow for more than one transmitter and/or receiver, the Model
370/375 and/or option board do not include any address recognition or collision avoidance and/or
detection to promote this usage. If the 20-mA loop is intended to be used in this manner, proper
planning for these issues is required.

SELECTION PARAMETERS

Selection parameters have a pre-defined list of choices to pick from. Each choice is numbered
and corresponds to a certain value. The choice number is shown to the right of the decimal point
within the parameter number. Repeatedly pressing [TARE] (Model 370) or [SAMPLE/Enter]
(Model 375) while viewing a selection parameter cycles through the available choices, or you can
key in the choice number.

P 200.00

Indicates Parameter Parameter Number Choice Number

For example, parameter 200 (P200) is a selection parameter that holds the baud rate for the
serial port. This is a selection parameter because a choice number between 00 and 12 must be
used. Each choice number corresponds to a different baud rate. To change the baud rate from
the default value of 9600 to 4800, perform the following steps from the Setup Mode.

To
