1.1 PRODUCT DESCRIPTION
BLH Remote Digital Displays (Figure 1-1, 1-2)
receive and display serial ASCII data transmitted
by a BLH host LCp100, LCp-200, or Baldwin
Model 2020 series weight indicator/ transmitter.
Operating on supplied data, the Remote Display
precisely duplicates the weight, rate*, or tension
value display of the host device. Indication also
includes gross, net, and level information. Figure
1-1 shows a typical Remote Digital Display
application.
Units require only a twisted pair of wires for
interconnection and mount up to 2000 feet from
the host device. Remote Display units are ideally
suited for applications where analog panel meter
resolution is not adequate. Analog displays
present only an approximation of actual weight
data whereas serial communication guarantees
digit-for-digit replication. Precision accuracy,
easy installation, and optional NEMA or
explosion-proof enclosures make these units the
perfect choice for plant or control room remote
display.
Introduction
Figure 1-1. Typical Remote Display Application
Front panel ZERO and TARE keys transmit
push to zero and tare commands to the host
device. The GIN (gross-net-rate) key, however,
functions independently from the host device.
For example, a remote LCp-200R unit can
display net weight or rate while the host LCp200 displays gross weight. CE Marked Remote
Digital Displays have passed both the EU
(European Union) Low Voltage and EMC Directives.

1.2 MOUNTING OPTIONS
For units located in a general factory/plant floor,
or if corrosive, hose down, or sanitary
requirements are a factor, a NEMA 4X stainless
steel enclosure is available. For Div. 2
hazardous locations, units are available with FM
approval as a non-incendive device. For Division
1 hazardous locations an explosion proof enclosure is available.

SECTION 2. Installation
2.1 INTRODUCTION
This chapter provides Remote Display mounting
and electrical installation information.
Instruments will operate accurately (to
specification) in locations with temperatures
ranging from -10 °C +55°C (+14°F to + 130°F).
The installation location should be free of vibration. Unless equipped with the proper
enclosure option, instruments should not be
located in areas containing explosive or
corrosive vapors. In all installations, ac (mains)
power should be supplied from a clean (transient
free) instrument power source.
2.2 MOUNTING
2.2.1 STANDARD UNIT MOUNTING
Standard Remote Display Units are shipped with
the necessary hardware for panel mounting.
Outline and panel cutout dimensions are
depicted in Figure 2-1. Installation of panel
mount adapters is shown in Figure 2-2.
2.2.2 OPTIONAL NEMA 414X ENCLOSURES
NEMA 4 and 4X enclosures are equipped with
four pre-punched holes for mounting to a wall
or bracket. A U-bolt can be used for mounting
to a pipe support. The enclosure should be
installed in a vibration free environment. If
conduit is used to shield interconnecting
cables, drains should be provided to reduce
the possibility of condensate entering the
enclosure. Outline dimensions for NEMA 4/4X
enclosures are presented in Figure 2-3.

Figure 2-4. Interface Overview
2.3 ELECTRICAL CONNECTIONS
Figure 2-4 presents an overview of all wiring
connections. Use this interface diagram for
interface connections between the Remote
Display and host instrument. Individual
connections are discussed in the following
paragraphs.
2.3.1 THE REMOTE DISPLAY REAR PANEL
Figure 2-5 shows the Remote Display rear
panel. Call outs depict wiring locations for all
electrical connections.
2.3.2 MAINS (AC) POWER
Remote Display instruments are shipped ready
to operate at 115 Vac (50 or 60 Hz). For 220
Vac operation, remove the rear panel and
change the internal voltage selection switch by
performing the following:
1) Remove the mother board screws.
2) Slide the mother board out about 3 inches
3) Change the AC switch on the right-hand
side of the board
Figure 2-5. Rear Panel Connection Locations
Each instrument is protected with a 1/4 amp, 250
volt T type fuse located adjacent to the ac power
socket. If the fuse opens, replace it with the same
type, current, and voltage rating.
2.3.3 SERIAL COMMUNICATION
A 4-socket mating half connector is provided
for serial communication wiring. Connect
wires for both units as shown in Figure 2-6.
Total cable length should not exceed 200 feet.

2.4 INTRODUCTION
Remote Digital Display is accomplished using
jumpers and DIP switch selections. Jumpers
determine the front panel display status and DIP
switch selection establish the communication
interface. Jumpers are added to the rear panel
Digital Input connector.
2.5 FRONT PANEL DISPLAY STATUS
Figure 3-1 gives a complete overview of jumper
status designations and locations. Designated
functions are discussed in the following
paragraphs.
2.5.1 DISPLAY MODE
The front panel display can be configured to
track the front panel of the host LCp/2020
instrument or fixed to display only one mode of
host operation. In tracking mode, any host mode
change (i.e. Net/Gross/ Rate) is immediately
transmitted and displayed upon the remote
display front panel. If a fixed display mode is selected, the remote unit displays only the selected
mode of operation regardless of changes made
to the host device. For example, a remote LCp200R can be fixed to display rate data only while
the host LCp-200 freely changes from Gross to
Net or Rate.
2.5.2 DISPLAY CONTROL
When any tracking display is selected, pressing
the front panel GIN key changes not only the
remote but also the host mode of operation. The
remote display selection is transmitted back to
the host and the host mode of operation
changes accordingly. If the zero and tare keys
are activated (next paragraph), all net, gross,
rate, zero, and tare functions can be controlled
from the remote display keypad.
Figure 3-1. Jumper Designations
2.5.3 ZERO AND TARE FUNCTIONS
For remote control of system zero and tare
functions, add jumpers 4 and 5 as shown in
Figure 3-1. Jumpers may be added
independently as desired, i.e., zero only (4) or
tare only (5).
2.6 COMMUNICATION CONFIGURATION
To ensure proper bi-directional communication
between the remote display and the host, set
DIP Switch SW1 on both units as shown in
Figure 3-2.
Figure 3-2. DIP Switch Designations
*Rate not available with LCp-100 based systems

SECTION 3. Operation
3.1 DISPLAY OPERATION
Upon power up of both units, remote digital displays provide digit-for-digit display duplication of the host
device display readout. Display updates, occurring approximately ten times a second, include weight,
rate*, level, and alarm status data. If a fixed display format is selected, the remote unit can display one
mode such as net or rate* while the host device displays a different mode such as gross.
*Rate not available with LCp-100 based systems
3.2 REMOTE CONTROL FUNCTIONS
When enabled, tare, zero, and gross-net-rate* selection functions can be performed using the remote display
front panel keys (Figure 4-1). Pressing a key causes the host to respond as if its own key had been pressed. The
only exception is the PRINT/COM key, which has no function at this time.
