1. Introduction
ABOUT THE MANUAL
The IQ plus 800 and 810 indicators are both very flexible, offering a variety
of standard features and optional features. This manual is organized so that
you can learn about the basic installation and standard operations first, then
find more detailed information about specific optional features in later
sections (see Table 1-1 for optional features).
The configuration menu charts include parameter choices for both the
standard features and all possible options. When configuring your IQ plus
800 or 810, you can ignore the settings for parameters dealing with options
not installed on your indicator. Settings chosen for non-installed options are
ignored.
OVERVIEW
For basic weighing applications, the IQ plus 800 or 810 has more useful
standard features than any other digital indicator currently available. For
more complex weighing applications, the IQ plus®800/810 series indicators
are expandable, programmable, process controllers with an impressive array
of options (see Table 1-2 for standard features and Table 1-3 for optional
features).
The economical IQ plus®800 indicator is available in a compact stainless
steel enclosure. It carries all the features of the standard IQ plus®800/810
indicators, but its compact enclosure size will not accept all the expansion
options of the larger 810 enclosures. See the Applications Chart (Table 1-1)
on the following page for a complete listing of options which will fit into the
various models.
The IQ plus®810 is available in desktop (DT), stainless steel batching (SS),
and hostile environment batching (HE) models. The 800 and all 810 models
are NTEP-certified for Class III and Class IIIL at 10,000 divisions.
The 800 stainless steel, 810 SS and HE models are certified for NEMA 4X
washdown applications. See page 9-1 for a complete list of specifications.

Table 1-4.
Numeric keypad
These keys let you enter numerical data. Normally, you key a number,
and then press ENTER and/or a function key. Each digit appears on the
display screen as entered. If you key a number and don’t press ENTER
and/or a function key within several seconds, the display reverts to the
previous mode and the number is ignored.
If you make a mistake entering a number, press CLEAR to erase a
single digit. Continue pressing CLEAR to erase the remaining digits as
necessary.
If you key a number and press G/N before pressing ENTER, the number
is erased and the display reverts to the previous mode.
Zero
Eliminates weight from the display (when in Gross mode). This key will
not function when the scale is in motion, displaying Net weight, or
beyond the selected zero range.
G/N
Toggles between Gross and Net display modes. In Net mode, the display
shows net weight and the “N” annunciator lights. In Gross mode, the
display shows gross weight and the “G” annunciator lights.
Also, you can use G/N to revert to normal weighing mode if in another
mode.
Tare
Zeroes the displayed weight and places it into the tare register. The scale
must not be in motion, as indicated by:
If you press TARE in Gross mode, the indicator automatically changes
to Net mode and tares the current gross weight. If you type in a value
using the keypad, then press TARE, the indicator tares that value.
The T and rhombus appear on the display when a tare is in the system.
The TE and rhombus indicate a manually entered tare.
Units
Toggles the display between the primary and secondary units. Although
the standard label shows pounds and kilograms, other units can be
defined in the configuration menus.
Print
Prints a ticket when pressed in Normal Weighing Mode. You can
configure PRINT to operate in one of three modes: as a simple print
button (normal weighing mode), as a revolving-terminal data entry key
(Truck In/Out Mode 1), or as a fixed-terminal data entry key (Truck In/
Out Mode 2). In all cases, PRINT only functions when the scale is at
standstill . Also, you can customize the ticket format (see
Custom Print Formatting Procedure in Section 9, Appendix).

format to enter time values.
Disp Accum
Displays the current weight from the accumulator register and sequen-
tially lights the accumulator annunciators. Press repeatedly to access all
five accumulators, or enter number (0 – 4) and press DISP ACCUM.
If you press CLEAR, the display prompts “CLR AC?.” If you press
CLEAR a second time, the indicator clears the accumulate register.
Disp ROC
Displays the rate of change for weight data on the current load cell
channel. This is expressed as the change in weight during a specific
period of time, such as lbs/min, gals/hour, etc. The “ROC” annunciator
lights when this mode is active.
This key only works if the optional rate of change feature is installed.
New ID
In the Truck In/Out mode, NEW ID lets you enter a new truck ID
number. Key in a number with the numeric keys and press NEW ID to
save. When a truck is on the scale, you can use NEW ID to enter the
new ID number, save the tare, and print a weigh-in ticket, all in one step.
Also, you can use NEW ID to enter an ID number not associated with
the truck program or weight storage (see Section 5, Operating Modes,
for more information).
Scale # (or BASE # for HE)
Selects an analog input channel or total of all channels to display.
The annunciator light indicates which input source or sources are
selected. If sources are totaled, more than one annunciator light is
illuminated.
Note: This key only works if more than one input channel is enabled and
selected.

If you make an error when keying in a value, press CLEAR to erase
individual digits. To return to the normal weighing mode, press G/N or
wait for the display to switch back.
You can use the SET POINT key to view or change PREACT values
from the front panel during the normal operating mode (see Section 7,
Setpoints and Batch Processing, for more information).
If you wish to customize the prompts given while using SET POINT,
you can define up to 10 unique names. See Section 7, Setpoints and
Batch Processing, Setpoint Mnemonics, for more information.
Clear
Erases digits entered from the keyboard or clears special function values.
In the SETPOINT function, CLEAR disables setpoints or erases
individual digits.
In the DISP ACCUM function, CLEAR erases the value in the
accumulator.
In the DISP TARE function (normal weighing mode) with the current
tare value displayed, pressing CLEAR causes the following prompt to
appear: “CLR TR?” Pressing CLEAR a second time clears the tare
register.
In the DISP TARE function (Truck In/Out mode), CLEAR erases truck
IDs, as well as tare values.
Annunciator lights

MAKING POWER CONNECTIONS
The IQ plus®800/810 can operate from either a 110VAC or 220VAC
3-wire power supply line at 50 or 60 Hz. It is further recommended that the
800/810 be connected to an AC power supply that is on a separate branch or
feeder from other AC equipment that causes step-load changes and/or other
AC line disturbances.
The transformer on the power supply / display board is pre-wired at the
factory for 110VAC operation. If the installation requires 220VAC opera-
tion, move the transformer connector from J5 to J9 on the power supply /
display board. Also, be sure to install the correct fuse. See Section 9 for a
complete list of Specifications.
CONNECTING THE BOARDS
The main CPU board connects to the power supply / display board with two
ribbon cables (see Figure 2-1). The power ribbon cable connects between J1
on both boards; and the data ribbon cable connects between J2 on both
boards.
!
Caution
To avoid damaging the
indicator, properly configure
the power supply / display
board before connecting to the
3-wire power supply line.

Leave jumpers JP1 and JP2 in
place for 4-wire load cell
installations. Remove them for
6-wire sense lead installations.
WIRING THE ANALOG INPUTS (LOAD CELLS)
Wire the analog input cable from the load cell or junction box to the
removable connector and plug into the CPU board at J10 near the A/D
module. If your indicator was purchased after June 1, 1996, the A/D module
will be surface mounted to the CPU board. See Figure 2-2 below for J10 pin
assignments #1-#7 for these indicators.
Note that earlier indicators (with A/D modules mounted on standoffs) have
J10 pin assignments in reversed order from Figure 2-2.
For a single-channel A/D module, use the upper plug-in connector for the
load cell. If a dual-channel A/D module is being used, plug the second load
cell cable into the lower connector at J10.
If using 4-wire load cell cable, leave on jumpers JP1 and JP2 that connect
pins 3 – 6 and pins 4 – 7 at terminal J10. For a 6-wire installation using
sense leads, remove the jumpers.

channel two. Leave the jumpers installed for a 4-wire cable, and remove
them for a 6-wire installation. See Table 2-1 for J10 analog input connec-
tions.

WIRING THE SERIAL COMMUNICATIONS PORTS
Terminal block J7 on the CPU board connects both the EDP (Electronic
Data Processing) port and the printer port. You must configure these ports
for your specific application (see Section 3, Configuration, for more
information). The EDP port handles full-duplex RS-232 or simplex 20 mA
current loop communication, with half-duplex RS-485 and full-duplex 20
mA current loop as optional features. The printer port handles simplex RS-
232 and 20 mA transmissions. Also, you can add another full-duplex serial
port to the system by installing the optional expansion board and auxiliary
serial port (see Section 8, Optional Features, for more information).
Table 2-2.

The following communications parameters (Table 2-3) apply to both the
EDP port and the printer port.
Table 2-3.
Serial communications parameters
• Continuous or Demand outputs
• 300, 600, 1200, 2400, 4800, 9600, or 19200 baud rate
• 7 data bits (with parity) or 8 data bits (no parity); 1 start bit and 1 stop bit
• None, odd, or even parity
• Line termination: <CR LF> or <CR>
• End of line delay up to 2550 milliseconds (2.55 seconds)
NOTE:
RS-485 requires a U24 chip.
Bidirectional 20 mA CL requires
a U22 chip.

2-8 IQ plus®800/810 Installation Manual
Continuous output serial data format
When you select continuous transmission in the setup menus (SERIAL
➥STREAM ➥EDP, PRN, or AUX), the IQ plus®800/810 uses the
Consolidated Controls serial data format as shown below:
<STX> <POL> <wwwwwww> <UNIT> <G/N> <S> <TERM>
ASCII 02
decimal char.
Polarity:
<Space> = Positive
<–> = Negative
Weight: 7 digits, right-justified, dummy
zeroes, decimal point with no leading zeroes
except for leading zero immediately
preceding the decimal point. Leading zeroes
transmitted as spaces.
L = pounds
K = kilogram
T = ton
G = grains
<Space> = grams
O = ounce
G = Gross
N = Net
Status:
<Space> = valid
I = Invalid
M = Motion
O = Over/under range
<CR> <LF>
or <CR>
Demand output serial data format
When you select demand mode transmission in the setup menus
(SERIAL ➥PRNDEST ➥EDP, PRN, or AUX), the IQ plus®800/810
uses a data string formatted for a basic ticket printout. However, you
can use the EDP port or keypad to fully customize the ticket (see
Section 9, Appendix, for more information on custom printing formats).
This allows the IQ plus®800/810 to work with a wide variety of
printers, scoreboard displays, and other remote equipment.
RS-485 communications (optional)
You can configure multiple IQ plus®800/810 indicators to operate on a
2-wire, multidrop RS-485 serial communications line. The expanded
serial communication option must be installed. To enable RS-485
communications, an optional chip, U24, must be installed on the CPU
board (see Section 8, Optional Features, for more information on
expanded serial communications).
NOTE:
If your application requires a
customized format, consult your
supplier for further details.

Installation 2-9
When planning an RS-485 installation, consider the following:
Table 2-4.
RS-485 hardware
• Every piece of equipment must have a unique address.
• Every piece of equipment must remain quiet while waiting for a
command.
• All interface wiring and RS-485 transceivers must be correctly installed.
Note that there are both 2-wire and 4-wire RS-485 implementations.
Although the IQ plus®800/810 uses 2-wire, you can incorporate other 4-
wire equipment in the system by tying the two transmit (A) pins together
and the two receive (B) pins together.
Table 2-5.
RS-485 software
• The controller software must be compatible with the IQ plus 800/810’s
protocol. Some equipment may have its own, proprietary RS-485
protocol.
• All equipment in the RS-485 network must follow the rules of half
duplex communications: “Be quiet unless spoken to;” and “Never echo
back what you are receiving.”
• The controller must turn on its transmitter, send the commands, wait for
the transmission, and finally, turn off its transmitter.
• The controller software must be able to handle the echo from its own
transmission, since the transmit and receive lines are the same.
The IQ plus 800/810 has a built-in RS-485 software protocol, which
you enable by assigning an address to the EDP port on the CPU board.
From the setup menus, the progression is: SERIAL ➥EDP ➥AD-
DRESS, where the address is an ASCII decimal value other than zero.
We recommend addresses of 65 or higher.
Since the RS-485 protocol requires that each device has a unique
address, all remote commands are initiated as shown below:
<STX> <ADDRESS> <COMMAND> <CR>
ASCII 02
decimal
character
Address of the receiving
IQ plus 810 indicator.
EDP serial command
ASCII carriage return character
NOTE: Host must send <CR>, not
<CR> <LF>. Failure to comply,
renders all indicators unable to
respond to serial commands.
If the initiating address matches the port address of an IQ plus®800/810
listening on the RS-485 network, that indicator responds.
