1. INTRODUCTION

FDT is a Remote Display Terminal specifically designed for use as remote weight indicator for
Digital Junction Box weigh systems (FAD-1 or FAD-4).
The unit maybe operated in the Master mode where it will poll all (max 30) FAD’s connected to it,
or in the Slave mode where it will only display information from a selected FA D.
Setup and Calibration of FAD’s is performed via FDT in the Master mode.
When several (max 30) FAD’s and FDT’s are connected on one cable, only one FDT is allowed to
poll the FAD’s. Communication in a master/slave network is based on LESIP serial interface protocol.

The unit may also be used as remote display for numeric indicators with continuous weight output

mode (LECW _ 2 format).
FDT may be used for legal for trade app lications when connected with one or more weigh scales,
since calibration data is stored in th e FAD.

The basic configuration VERSION A includes:

1. Serial port RS485A with network capability.

2. Front panel with 6 digit LED display plus 5 annunciators and 6 membrane keys.

3. Non volatile memory for system parameters and calibration data.

4. The setting of the unit is done through a guided keyboard operation, enabling the adaptation
to operating environment and system requirements. Two setup procedures are executed. Fn 49
for calibrating the FAD and Fn 4 6 for settin g up op eration mode and communication parameters
of FDT.

The advanced configu r ation (VERSION B) includes additionally:

1. Real time clock calendar with rechargeable battery backup.

2. Serial port RS232 adapter for printing weighing data on a serial printer and /or

bidirectional communication with a host computer.

3. Non volatile memory for storage of 10.000 weights.(Electronic tally roll or Alibi memory).

OPTIONS

OP.5 230 VAC to 9 VAC/ 500mA, mains power adapter.

4. OPERATING MODES

FDT may be configured accordin g to the applications, to be operated in 4 different modes.

4.1 REMOTE DISPLAY - CONTINUOUS WEIGHT INPUT

The unit displays information received from the serial port(s) according to LECW_2 format

(P + 123.45 “CR”). RS485A may be received from port 1 (Version A or B). Baudrate and data

bits are programmable in SETUP 3.

RS232C may be received from port 2 (Version B only). Baudrate is fixed at 1200 baud. No or

even parity and 7 or 8 data bits are programmable in SETUP 2. 20 mA , current loop passive may
be connected to the RS232 port (Tx+ to Tx and Tx– to Rx).

SET UP REQUIREMENTS (Port 1 9600, E, 7, 1 or Port 2 1200, E, 7, 1)

1 Don’t care
2 2d = 17, the rest set to Zero
3 3t = 01, 3b = 96, 3d = 17

Upon power up a search is performed by the unit for input data from each serial port. If data is
input from port 1 it will be displayed. Else it will search port 2. If no data is received by any
port E30 will be disp layed until data reception is restored.

DO NOT CONNECT BOTH PORTS SIMULTANEOUSLY.

4.2 MASTER DISPLAY & KEYBOARD FOR FAD(S)

In this mode of operation the FDT polls the FAD(s) and displays their data. Commands such as
“Zero”, “Tare” etc. are issued to the FAD via the FDT’s keyboard.
Calibration of the FAD is also possible through a dialogue in the FDT. A number of FADs may be
connected in a network with one FDT acting as the master. The FAD address whose data is
displayed, is keyboard selected with Fn 01 to Fn 30 corresponding to FAD A to ^.
The default address is A ie the first FAD in the network.

SETUP REQUIREMENTS (9600, E, 7, 1, FAD address A, Nr of FADs = 4)
1 Application dependent
2 Application dependent
3 3t = 02, 3b = 96, 3d = 17, 3.n = 4, 3E = 65.
4

The F DT always polls FADs in seq uen ce, starting from address A and increments the add ress until
the programmed number of F ADs (set up 3 .n) where it circles back to A. The cycle is repeated as
long as the FDT is in th e weight display mode. Polling is paused while in the function menu or
printing etc. The selected (Fn 01 to Fn 30) FAD may displayed or calibrated via the FAD
calibration procedure in the FDT while all FA Ds are polled. This however limits the response time
of the selected FAD. Refer to ch apter 5 for details of set up and calibration procedures.

4.3 SLAVE DISPLAY FOR FAD

The unit is connected in a F AD network. FAD unit(s) are scanned by a master unit which may be a
personal computer or another FDT. The slave FDT will display all data (weight and
messages) originating from the FAD with the same address.

SETUP REQUIREMENTS (9600, E, 7, 1, FAD address A)
1 Don’t care
2 Don’t care
3 3t = 03, 3b = 96, 3d = 17, 3E = 65, the rest don’t care.

Keyboard operation is normal except that no commands are transmitted to F AD’s and printing or
totalizing is inhibited. The unit may display data from any of 30 FADs in a network . the

selection is performed by Fn 01 to Fn 30 corresponding to FAD address A to Z (41h to 5Eh).
Only polled FAD s are displayed, so the master in the network must have been set up to poll all
FADs, accordingly. The master may poll the add ressed FAD units sequ entially or in any order of
frequency. The FDT will p ick up the selected FAD data and display it.

4.4 DUAL FAD MASTER MODE (SCALE A/B)

The F DT p olls two FA Ds A and B conn ected to load cell scales. T he u n it may display the weight
from scale (A) or from scale (B) or the su m of the two weights (A +B). Ind ividu al scale weights or
the sum of the two may be printed or totalized or transmitted to PC. If scale A or scale B is
selected the operation is normal sin gle scale where the display and keyboard op erate for this scale
only. If (A+B) is selected display and keyboard operation is similar but with few specific
limitations.

Selection of A or B or A+B is performed by key I and is indicated in the front panel by the
Annunciators L ; . (A+B)=Both illuminated.

The (A+B) mode has the following operational characteristics:

- If any of the two scales is out of range the (A+B) is out of range.

- For the “NO MOTION” condition both scales must be stab le.

- For the :CEN TER OF ZERO” cond ition both scales must be within 0,25 division.

- Switching to Net mode is supported provided both scales are in Gross or Net mode.
If any of the scales is in NET mode it will automatically be switched to GROSS mode.

- If any of the FAD s displays a message instead of weight, this message will be d isplayed
on the FDT.

- The Fn key is not operational in (A+B) mode.

For approved scales if A+B mode is used the scales must have the same display step.

5.2 CUSTOM PRINT FORMATS

T hese are data strin gs for transmission to a p rinter. The formats are ed ited by the user (any ASCII

editor) and downloaded to the unit via the serial port RS232. When a print operation takes place
the FDT will insert the scale variables in selected positions in the string specified with [!123],
where 123 is the decimal code of the variable. E.g. scale variable 40 (Net) should be inserted as

[!040].
Non printable characters may be inserted in the string specified as [@123], where 123 is
the decimal equivalent of the character code. E.g Esc E (1Bh, 45h)is inserted as [@027]E.
This may be repeated as many times are required in the string.
The following scale variab les are implemented in the FDT.
A/A DESCRIPTION LENGTH
007 Weigh number 4 digit
008 Totaliser 7 digit + decimal point
030 Date 8 digit
032 Time 5 digit
036 Tare 5 digit + decimal point
038 Gross 5 digit + decimal point
040 Net 5 digit + decimal point

Two formats may be downloaded, 1 & 2 , 512bytes each. Format is transmitted in Gross mode,
while format2 is transmitted in Net mode. For the user defined formats to operate SETUP2/2.t=20.
The formats are downloaded to FDT using the Fn 41 , Fn 42 procedures (see chapter 6)
or command F (see chapter 8.2)

A test printout should be performed to validate the format.

8. COMMUNICATIONS

Version A has one communication port RS485A (SERIAL PORT 1). This is the port used for
connection to FAD(s) and for networking.
Version B has in addition to serial port 1 an RS232C port (SERIAL PORT 2), used for connection
with printers or personal computers.

8.1 SERIAL PORT 1 (RS485A)

The port operates in half duplex mode. Communication is based on “LESIP” master / slave serial
interface protocol. (See “LESIP” with FAD appen dix for details).
Baudrate and databits are configured in FDT setup 3.
Cable connections are shown in Annex A “CONNECTOR & CABLE DIAGRAM”.

8.2 SERIAL PORT 2 (RS232C , VERSION B ONLY)

The port operates if full duplex mode. Baudrate is fixed at 1200 bits/sec. 7 data bits, even parity or
8 data bits n o parity may be selected in FDT SE T UP 2.d. The fu nctionality of the port is
also programmed in set up 2. The different modes of operation are detailed below:

8.2.1 CONTINUOUS WEIGHT OUTPUT

The indicated weight and status information is transmitted continu ously. No handshake is required.
Data is output from Pin 3 = Tx and Pin 5 = GND

8.2.2 PRINTER OUTPUT
The weight and date time may be printed on.

A serial printer connected with DTR protocol (See Annex A for connection details).
Several print p ossibilities maybe selected in FDT SETUP 2. In addition two custom print formats may
be created and downloaded to the FDT via the serial interface RS232. (Refer to function menu,
chapter 6, Fn 41, Fn 42).

SET UP REQUIREMENTS
1 Application specific
2 2.t = 01 (Date, time, number, weight)
or 2.t = 05 (Gross, Tare, Net, quadruple size)
or 2.t = 06 (Single line Nr, Gross, Tare, N et)
or 2.t = 20 (Custom format 1 in Gross mode, Custom format 2 in Net mode)
3 3.t = 02 or 04 The rest are application specific.

Standard formats may be displaced on the paper by selection of formatting parameters in set up 2.
Parameter 2.3 in set up 2 may be selected to inhibit printing weights below min.
Parameter 2.6 in set up 2 may be selected to inhibit further printouts until the scale weight falls below
min in order to avoid double printing and / or totalising.
Printed weigh ts may be totalized if set up 1.1 = 1.
Parameter 2.7 in set up 2 enables a paper out or printer error to be detected.

Printing is initiated by key P provided that the weight is stable positive and within weighing range.

8.2.3 HOST COMPUTER MODE

This mode is used to communicate with a Host computer. The Host transmits a command and the
FDT replies with the required data or executes the command.

SET UP REQUIREMENTS (1200, E, 7, 1, A)
1 Application specific
2 2t = 09, 2d = 17, 2E = (A-Z)
3 3t = 02 or 04. The rest are application specific.
For approved installations the “ALIBI MEMORY” must be active (set up 1.2).

The following commands have been implemented.
