5 Serial interface/DIP switches
The RS 232 serial interface is connected via the built-in 9-pin sub-D-connector. Alter-
natively, RS 422, RS 485 or 20 mA interfaces can be connected via the terminals.
The interface standard is selected by setting DIP switches S7 and S8.
Since the control interface unit incorporates only one serial interface, which operates
with different drivers and receivers for the various standards, only one standard inter-
face may be connected at any one time.
The transmission speed (baud rate) is set with DIP switches S1, S2 and S3 as follows:
Data is transmitted using one start bit, 8 data bits, one stop bit and no parity bit. The
control interface unit also responds to one-and-a-half and two stop bits.
In the basic fixed-code operating mode, the following data formats are possible:
8 data bits, no parity
7 data bits, even parity
7 data bits, odd parity
To set these transmission formats, the command RST (in upper or lower case, but not
in combination) must be sent to the control interface unit immediately after power on.
The control interface unit adjusts automatically to the required format.
In binary mode, the number of data bits to be transmitted is always 8. If 7 data bits are
set, the control interface unit will return the error message “M5” in response to the
command “SB”.

5.2 RS 422 and RS 485 interfaces
With these two standards, the data signal is defined as the voltage differential be-
tween two conductors. Since possible interferences have the same effect on both
conductors, provided a tightly twisted pair is used, a more secure data transmission
is obtained than with the RS 232 interface, particularly at high transmission rates.
The RS 422 standard provides a symmetrical four-wire connection that is insensitive
to interference. The transmit and receive lines are separate, so that full duplex oper-
ation is possible.
With the RS 485 standard, the transmit and receive lines are coupled, permitting half-
duplex operation only. The transmitter is disabled to allow the receipt of data. The abil-
ity of multi-point connections is not implemented in the control interface unit.
Connection details are shown in the diagram on page 3. Terminals 15 to 18 should be
used for the RS 422. For the RS 485, Terminals 17 and 18 should be connected.
5.3 20 mA current loop or TTY interface
The TTY interface was originally designed for teletype control. Two pairs of conduc-
tors are used, one to send, and one to receive data.The data can be transferred in full
duplex mode, which is not supported by the control interface unit. Current loop trans-
mission is very resistant to interference and therefore offers secure data transmission,
even where long lengths of cable are used.
The current loop connections of the control interface unit are galvanically isolated by
opto-couplers. The control interface unit represents the passive side of the transmis-
sion, i.e. the current and voltage required for transmission must be provided at the
other end.
5.4 Connection cables
The maximum cable length between the control interface unit and the host computer
will vary according to the data transmission speed, the interface standard and the lev-
el of interference. For this reason it is only possible to give approximate values:
A screened twisted twin-core cable with a minimum wire cross-section of 0.14 mm2
should be used for the connection.
The screen of the read head lead is connected on both sides to earth (PE) with low
resistence and low induction. For that the attached terminal block can be used (see
figure 5.3). Please make sure that the screen is kept as small as possible.
Standard Max. cable length
RS 232 15 m
RS 422 1000 m
RS 485 1000 m
20 mA current loop 1000 m

Bild 5.3: Terminal block with connecting cables
Read head cable lengths up to 50 m or 100 m are possible if the following conditions
are satisfied:
up to 50 m read head cable:2cross sectional area of at least 4 x 0.25 mm2
maximum resistance 78 Ohm/km
maximum capacitance 90 pF/m
(e.g. LIYC11C, Mukkenhaut & Nusselt MUNFLEX
C11Y)
up to 100 m read head cable:2cross sectional area of at least 4 x 0.5 mm2
maximum resistance 37 Ohm/km
maximum capacitance 90 pF/m
With a cable length of 100 m, a series resistor of 82 Ohm must be fitted
in the cable connected to the 'Reset' terminal of the control interface
unit.
Since more EM interference can result with longer cable lengths, the
maximum cable lengths given above might not be possible for some
applications.
If leads with double shielding are used, e.g. metallic wire mesh and
metallic foil, they must be connected to each other using a low imped-
ance connection at one end of the cable.
Many noise impulses come from the supply cables, e.g. switch-on cur-
rent of a motor. For this reason, running the supply cables in parallel
with the data/signal cables, especially in the same cable duct, should be
avoided.

X is transmitted instead of the read head number, all connected read heads are inter-
rogated in succession. The code is read and transmitted followed by the number of
the read head (R mode). In AR mode, reading continues until a code carrier can be
read. In CAR mode, all the connected read heads read continuously until a new com-
mand is entered.
After power-on, read head 1 is selected. If no read head number is specified, the pre-
viously selected head remains valid. Selecting read head 0 disables all read heads.
This is useful when energy consumption needs to be kept to the minimum.
Command Description
R Read mode
The read head reads the code once. The control interface unit trans-
mits the code or transmits an error message if it is unable to read a
code carrier.
AR Autoread mode
The read head reads continuously until a code carrier is available.
The code is then output. This mode can be cancelled by entering a
new command.
CAR Continuous Autoread mode
This mode corresponds to the AR mode. The code carrier is read and
the code is output. The command then remains active, i.e. the code
carrier is read again and the code transmitted etc.
BAR Buffered Autoread mode
In Continuous Autoread mode, a code carrier in front of a read head
is continuously read and its code is transmitted. Since all these codes
have to be processed by the higher-level control system, this can
lead to an overload. A solution is provided by use of the command
BAR, which causes a code to be transmitted once only. Only when a
new code is identified or when the system repeatedly fails to read a
code, will a further code be transmitted.
Note that in a high-interference environment, a code may be transmit-
ted a number of times, since it may be temporarily unrecognizable due
to interference and then transmitted again as a new code.

There are also system commands, used to input control statements to the system,
such as restart, switch to binary mode, or output the software version number. The
system commands are executed in both normal and binary modes. In the case of the
system commands, no additional parameters are required.
6.1.4 Data formats for the basic fixed code operating mode
For each command, it is possible to specify the data format in which the codes, when
read, are to be transmitted via the serial interface. If the data format is not specified,
the previously selected format will be used. If it is specified, it must be preceded by a
comma to distinguish it from the read head number. When the system is switched on,
data format 10 is set, and the data output is in ASCII character format. Binary repre-
sentation can be selected with the command SB.
Command Description
RST Restart
This command cancels all previously programmed commands and
resets the control interface unit to the basic settings, i.e. with no
active read command and using data format 10. The control interface
unit recognizes the parity setting on the received characters R, S,
and T and adapts accordingly. Since this command enables the con-
trol interface unit to identify the parameters for serial transmission,
the command must be entered either all in upper case or all in lower
case.
SB Set binary mode
All the data read is transmitted one byte at a time, one byte consisting
of 8 data bits. This format is possible only if the serial interface is set
to transmit 8 data bits per byte, and should be used when transmis-
sion speed is a priority.
The command “SB” is valid only if data format 28 has previously been
set via a read command. The RST command is used to exit the
binary mode.
SD Set double sided mode
In this mode, code carriers ICC-50 and ICC-50F are read from the
back, i.e. the side away from that carrying the code. With these code
carriers, the same read distance may be achieved on either side.
Note that in the worst case, the read time may be doubled. The dou-
ble sided mode can be cancelled by transmitting the command RST.
VER Version number
This command is used to request output of the software version num-
ber.

In the basic setting, all data is output in the form of ASCII characters. Depending on
the data format, this is either a decimal number or in hexadecimal form. In binary
mode, all data is transferred without conversion into ASCII characters. The distinction
between decimal and hexadecimal numbers does not apply. Binary mode is not per-
missible in data format 10, the basic setting. The code is always sent in the form of
ASCII characters.
In Data Format 10 the first 12 bits (A01h = 1010 0000 0001b) are transmitted as a
hexadecimal number. The next 16 bits (1C3Eh = 0001 1100 0011 1110b) are convert-
ed into a decimal number (1C3Eh =7230d). The code is NOT preceded by a read
head number. Therefore, the use of “X” as the read head number is only of use when
only one read head is connected. Thus, in this example, the following character string
is transmitted:
There is no provision for the binary mode in data format 10.
In Data Format 28, the first 12 bits (A01h = 1010 0000 0001b) and the next 16 bits
(1C3Eh = 0001 1100 0011 1110b) are converted separately into decimal numbers
(A01h = 2561d and 1C3Eh =7230d). The code is preceded by the read head number,
followed by a space. The character string transmitted is as follows:
Data format Description
10 This format is active when the control interface unit is switched on
and after transmission of a reset command (RST). The 64 bits of a
code carrier are read, but only 28 bits of data are output. The read
head number is not output. The first 12 bits are transmitted in
hexadecimal notation and the next 16 bits in decimal. All informa-
tion is transmitted in ASCII format: binary mode is not permissible.
If binary mode is selected, an error message is output.
28 The 64 bits of a code carrier are read, but only 28 bits of data are
output as a decimal number. There is no decimal conversion in
binary mode. The code is preceded by the number of the read
head, followed by a space.
