It is advisable to do a detailed reading of this Manual before mounting the instrument. This Operator's Manual
contains all the technical specifications : electricals as well as mechanics, both necessary to do a correct
installation and also a good use of the instrument.
At the same time the user will acquire the knowledge needed to obtain the best performances of the product.
Check that inside the present cardboard box, there are the following :
1 Instrument Model BDF-XX-S.
1Operator'sManual.
1 Connector for Power Supply.
1 Screw-clamp connectors, 4 pins female for signal inputs.
2 Pieces for fixing the unit against the panel.
REFERENCE KEY
All models have a label on the rear part with their references printed on the following format :
Power supply
0 = 230 Vac 50/60 Hz.
1 = 115 Vac 50/60 Hz.
BDF- XX- X- X-X
Page : 5
3.- MAIN FEATURES
The BDF-XX-S are a four or six digits plus polarity (only minus) character remote display module. They accept
serial ASCII coded data into a differential or single ended line receiver, at common baud rates.
Numeric data and a selection of other characters can be displayed. The character set includes decimal point,
overload/alarm and negative sign. Simple messages e.g. Hi Al, Lo Al, °C, °F can be formed with characters
presentableonsevensegmentdisplays.
Units connected on a common data line may be individually addressed. This is achieved by sending code 03
followed by 02 (or XOFF XON), an address from 0 to 31 (ASCII 30 to 4F) and the data. The address 0 (ASCII
30) is common to all remote displays for simultaneous display of the same message.
Theunitmay be switch programmed to operate in a "strobed"modewhereby the data string is transferred to the
display on reception of a carriage return. Alternatively a "shift" mode can be used in which the characters are
displayed according to their current position in the input shift register.
Serie BDF-24-S : 4 digits type LED, seven segments, red or green colour with 57 mm (2.3") height and
minus sign for polarity.
Serie BDF-44-S : 4 digits type LED, seven segments, red or green colour with 100 mm (4") height and
minus sign for polarity.

6.3.- SIGNAL INPUT CONNECTION
The serial ASCII input circuit can be set to one of 10 arrangements. Unless otherwise specified at the time of order,
the input circuit will be factory default set for RS-232 levels. If you are in any doubt about the input conditions, it is
advisable to remove the rear panel of the unit and inspect the internal jumper switch positions.
The operating mode of the unit and baut rate are, unless otherwise specified at the time of order, set for the default
settings of :
MODE : strobed display BAUD : 1200 ADDRESS : 0 BITS : 8 PARITY : none
If you are in any doubt about these settings, they can be determined by powering up the unit with the input line idle,
and observing the display at power-up.
To change any set-up conditions see the configuration section
The unit has a protection fuse located on the power supply
socket.
If this fuse must be replaced or changed because the power
supplyis changed, use the time-lagfuse according to IEC 127/
2 with the values indicated on the table.

it means that the instrument is ready to receive data, and all printable characters received (20, 2B, 2D, 2E and
30 to 5F) will be displayed directly if the instrument is programmed in shift mode or after receiving the code 0D
in strobe mode.
It is convenient in this moment and before starting the addressing mode, to send a character XOFF or ETX to
clear the internal buffer from uindesirable data. (XOFF recommended).
7.2.- OPERATING MODES
The following serial ASCII protocols are DIP switch selectable :
Mode 0 : Each printable character as it is received is placed in the least significant position and all characters are
shifted left one position. Following a carriage return character, the next valid character received causes
thedisplaytoclearandthatcharacterisplacedintheleastsignificantposition.(Ifitisaprintablecharacter)
Mode 1 : Printablecharactersareplaced in a buffer onreception. Receiptofthecarriagereturncharactercauses
the buffer contents to be transferred to the display.
7.-OPERATINGDESCRIPTION
7.1.- POWER-UP
Having determined that the unit has been configured for the correct input signal, connect the mains plug to a
suitable AC power source and the signal input to the signal source.
Ensure that the source is an idle condition, i.e. not transmitting data, and switch on the mains power.
The unit will power-up displaying its recognition address, its baud rate, the condition at the signal input, its
operating mode, the parity and bits number.
The display will be as follows :

7.5.- BS4505 SUBSET
The display powers-up responding to and, if appropriate, displaying the characters sent to it. Having received the
character EOT, the display switches to respond to a sub-set of the BS4505 protocol. The four characters received by
the display subsequent to EOT are the group number sent twice and the ID number sent twice. If the characters are
equivalent to the address of the display (set by internal jumper switches) the display switches to a listening condition,
elseitignoresanyfurthercharactersuntilEOTisagain transmitted. Once listening, the STX character isusedtostart
recognition and display characters, and ETX is used as a terminator to strobe data into the display and stop further

In shifted mode the character is entered in the least significant place
and all characters are shifted to the left (from LSB to MSB).
The character number 7 (from LSB) is lost (polarity and overrange),
the character number 6 (MSB) takes the polarity place. It is valid also
for the instruments with four digits because the polarity remains in 7th
position and characters 5th & 6th will not be displayed.
In strobed mode the data is placed in a register rather than the display.

9.- CONFIGURATION PROCEDURE
If it is necessary to change the configuration of the instrument, proceed as follows for all models,
series BDF-XX-S
1.- Check that the instrument is not powered.
2.- Remove the rear cover taking off all the screws to obtain access to the control board.
(See page 6 paragraph 4.3).
3.- Remove all jumpers on the control board. (See paragraph 8.2)
4.- Select brightness using DIP switches 1 & 2 (Selector S4).
5.- Select baud rate using DIP switches 5, 6 & 7 (Selector S4).
6.- Select operating mode using DIP switches 3 & 4 (Selector S4).
7.- Select address using DIP switches 8, 9, 10, 11 & 12 (Selector S4).
8.- Select number of bits and parity using jumpers R, S & T (Selector S3).
9.- Select signal input using jumpers A, B, C, D, E, F, G, H, I & J (Selector S1) and K, L, M, N &
O (Selector S2).
10.- Check that the level logic configuration is the appropriate, if not use jumpers K & L.
(Selector S2).
11.- Close the rear cover using all the screws removed before.
12.- Power-up the instrument with the appropriate power supply.
