Safety
Intended use
The IQT-... serial read heads are designed to be stand-alone. Only one read head
can be connected to the RS-485 line at a time. The serial connection should be
shielded and grounded at both the read head and the cabinet. Proper wiring
must be used.
Protection of operating personnel and the system is not
ensured if the module is not used in accordance with its
intended purpose.
The IQT-... read heads may only be operated by trained
professionals in accordance with these operating instructions.
General safety instructions
Any use other than that described in these instructions endangers the safety
and functionality of the device and the connected systems.
Only a qualied electrical technician may connect and perform maintenance on
the live device.
If malfunctions cannot be eliminated, take the device out of service and secure
it from accidental use.
Only the manufacturer can make repairs to the device. Interventions in and
modications to the device are not permissible and render the warranty null and
void.
The responsibility for the adherence to local safety standards lies with the
operator.

Tags
13.56 MHz frequency range (inductive)
Tags in this frequency range oer a signicantly higher read rate than tags
in 125- and 250-kHz systems. Since this is a non-proprietary system, cost-
eective tags are available from many third-party manufacturers. The 13.56 MHz
technology also makes so-called smart labels possible (tags as stick-on foil with
a printed optical barcode).
Available tags have a 64 bit ROM and 896 bits (IQC21-...), 256 bits(IQC31-...),
2048 bits (IQC22-...), or 7936 bits (IQC24-...) of freely programmable memory.

Operation through the communications interface
The commissioning of the IQT-... read head is described below using the serial
RS-485 interface, a PC, and a model number IPC21 tag. All the steps below
assume that the IQT-... read head is in the factory delivered state.
The factory setting of the transmission rate is 9600 baud with a 100 ms timeout.
The data carrier type is preset as "20" (tag type independent).
Check whether you have connected an RS-485 interface.
The transmission rate (baud rate) is selected through the software (see
"Instructions for connecting communication interface" on page 8). The
following transmission rates are available:
1200, 2400, 4800, 9600, 19200, 38400 bps
When delivered from the factory, 9600 baud is congured. The device works
with the following xed parameters:
• 8 data bits
• 1 start bit
• 1 stop bit
• no parity
First operating step
On the PC, open the terminal program (e.g. Hyperterminal or the command entry
window of the "RFID control," software which can be downloaded from our web
page, www.pepperl-fuchs.com).
In the terminal program, set the interface conguration to 9600 baud, 8 data
bits, no parity, 1 stop bit, and no protocol/handshake.
If you now switch the power supply to the device o and on again, after the
power is restored the following message appears on the terminal:

This tells you that communications are working between the device and the
terminal program and that the device is ready to operate. As a check, send the
version command
VE#<CR>
from the terminal. This command should be typed into a text le and sent.
Typing on the screen directly will fail because of the 100 ms serial timeout.
Depending on the device connected, you will receive a response with its name,
part number, and a version message.
Example:
0 (C) P+F IDENT-I<CR><LF>
IQT-18GM-R4-V1-Y911215<CR><LF>
#911215<CR><LF>
1830635<CR><LF>
05.04.07 #<CR>
Note
If you receive a dierent response, communication between your PC
and the device is not working correctly (the software number and
software date, however, may vary).
Check your installation and repeat the steps for commissioning.
Note
The device ignores capitalization of the commands. That is, commands
are not case sensitive. However, please note that all parameters follow
the command without spaces.
Protocol with checksum
All commands are concluded with the characters
<CHCK> = "Checksum"
and
<ETX> = "End of Text" (<ETX> = 03h).
These are used for data security in the serial transmission.
For simple operation from a standard terminal, the control unit can also accept a
#<CR>
instead of
<CHCK><ETX>.
Note
By using the checksum, you increase the data security on the interface.

IQT-18GM-R4-V1-Y911215
IQT-FP-R4-V1-Y911204
The checksum is calculated using simple addition of all previous characters with
no overow.
Example of the calculation of the checksum:
For the message without the checksum
VE#<CR>
or
ve#<CR>
the checksum should be calculated.
First, an ASCII table is used to look up the hexadecimal values for the characters
"V" = 56h and "E" = 45h
or
"v" = 76h and "e" = 65h.
If these are added, the result is:
"V" = 56h plus "E" = 45h gives the sum 9Bh
or
"v" = 76h plus "e" = 65h gives the sum DBh.
The message with checksum is then
VE<9Bh><ETX>
or
ve<DBh><ETX>.
If a longer message is to be transmitted, there will probably be an overow in
the checksum. That is, the value obtained from the addition will no longer t in
one byte. The overow is discarded.
To transmit the message
ER000702#<CR>
with a checksum, the following checksum results:
45h + 52h + 30h + 30h + 30h + 37h + 30h + 32h = 1C0h.
After the overow is discard, the following message results with the checksum:
ER000702<C0h><ETX>.
The device ignores capitalization of the commands. However, please note
that dierent checksums result for upper- and lowercase letters. Also, do not
send the ASCII characters "C0". It is the single ASCII character which has a
hexadecimal value of C0. Many characters cannot be entered directly at the
keyboard.

Commands
General information about serial interface
The RS-485 serial interface allows simple, fast connection of the IQT-... read
head to a PC or PLC. No device address is used. Conguration is limited to
setting the desired baud rate and serial timeout desired.
Command examples
1st example: Setting the tag type
When delivered, the tag type 20 is congured. This tag type is used when you
want the read head to automatically determine the tag type. The 64 bit code
is read rst and the tag type is set accordingly. Because the code is read rst,
the response time is increased by at least 20 ms. To make the system as fast as
possible, set the tag type exactly to the model number used (ex. IQC21 to 21).
To do this, you send the command "change tag."
As a response you receive:
This shows that the read/write head has correctly received the command (status
= '0'). You can nd an overview of all status codes on page 28.
The data carrier type is stored in non-volatile memory.

2nd example: Writing 2 double words starting at address 7
Now place an IQC21 tag in front of the read/write head. Send the command
"single write words" (for the syntax of this command, see "single write words"
on page 24).
If the tag is in the detection range, then you receive the message
0#<CR>.
Otherwise,
5#<CR>
is returned to show that writing was not possible because the tag was outside
the detection range (status = '5'). You can nd an overview of all status codes
on page 28.
The LED on the read/write head ashes green if the read command is activated
and turns yellow if the command has been executed successfully.
3rd Example: Reading 2 double words starting at address 7

Command types
When using commands, the two modes "Single mode" and "Enhanced mode"
are dierentiated.
Single mode
Each command is executed once, and an immediate response is returned. To
use this command, the tag must stop over the read head before the command is
sent by the control system.
Enhanced mode
Each command remains active until it is cancelled by the user, a new command
is sent, or there is a power cycle. A response is sent when the tag shows up
in front of the read head and also when it leaves the detection zone. These
commands are typically used to read tags "on the y."
