Section 1 –General Information
This manual provides information pertaining to the installation and operation of the Model HF-
3600E-RS232 13.56 MHz Reader. This series of Readers are a single piece solution Reader + internal
Antenna with integrated processor in enclosure. This Reader is unique in that it can operate with four
different types of RFID Tag chips, ISO 15693, ISO 14443A, ISO 14443B, and NXP’s original Icode1
(the latter not being an ISO standard). Under these standards there are varying amounts of Tag
memory, all of which include a non-alterable ROM UID (unique identification) section that acts as a
RO (read only) random identifier, guaranteed unique.
This Reader and the RFID Tags can also be provided as a proprietary product for brand protection
applications. This Reader is simple to use, plug & play, in that all commands and reports are
represented in standard human readable ASCII when used through a terminal program. It is not
necessary to convert commands to hex nor translate the outputs from hex as this work is done in our
processor. A Windows based Configuration and Applications software program is also available, as
well as an SDK.
The Reader operates as both a transmitter and receiver, providing a high frequency electromagnetic
field at 13.56 MHz to energize and activate an electronic transponder (RFID Tag). Once the Tag is
energized it modulates its data back to the Reader which in turn detects and demodulates this data for
delivery to the serial port.

Wire Specifications
Shielded co-axial cable with an 8pin M12 connector. RS232 has a maximum effective distance of
50’, use RS232 to RS422 converters if distance up to 2k’ is necessary. If you are not using a
concentration block and prefer a direct connection, we do offer an accessory cable with 8pin M12 for
connection to the Reader which splits to a 9pin D-sub serial connector and quick connect power
connector. The 9pin serial connector is pre-wired to act as a null modem with pins 2 and 3 being
crossed.
Power & Communication Connection
Regulated power supplies are preferred, linear power supplies are acceptable, switching power
supplies should never be used as they affect the Reader’s read range performance. Take care that
while some supplies are labeled as regulated, they are actually switching. Contact the source of your
supply or contact RFID, Inc. technical support with the make and model number of your supply.
RFID, Inc. can provide an AC adaptable power supply suitable for use with this Reader.

Section 2 - Quick Start Installation Guide
Software
Go to https://www.rfidinc.com/resource-center/ and choose the HF Complete option. Download the
zip file. Therein is contained an executable file for the program depicted below, as well as video
tutorial. Save those files to a folder on your PC and create a shortcut on your desktop. Open the HF
Complete file. You may have to temporarily turn off your firewall especially if you have Norton.
The file is safe, do not worry. Once opened you should see this screen:
Connect the Reader to your Windows based PC or laptop via the USB cable. If your PC or laptop
does not have a 9pin serial port, use a Serial to USB adaptor. These can be sourced for about $10.
You should now see a green LED at one corner of the Reader.
In the program, you can check “Auto Detect”and the settings of Baud Rate, etc. on your PC will be
detected once you select “Scan Ports.”In the off chance the Baud Rate does not automatically detect,
yet continues to cycle, you should uncheck “Auto Detect.”Either way, follow these procedures.
Select “Scan Ports”in the upper right. At upper left use the pulldown menu under “Port”and choose
the port shown. Now choose “Connect”in the upper right. You should now see this pop up.

This indicates the Reader is now connected. The settings at the top of the HF Complete program of
Baud Rate, Data Bits, etc. are the settings on your PC. All other same settings further down in the HF
Complete program are the settings of the Reader and will fill in once you select OK in this pop up.
Defaults are 115200 baud, 8 data bits, none parity, 1 stop bis and none Flow Control, ASCII Mode,
Direct Read Enabled, Single Read Mode to read UID memory section of Tag.
If at any time you see this pop up, re-power the Reader.
About the HF Complete Program
It should be understood this program offers both the features of a Configuration App (Config) and
Operations App (Run) in a single program.
Configuration App (Config) - Think of Configuration options as the settings you’d prefer for your
Reader. Selections that are considered as Config are generally white, like Port, Baud Rate, Data Bits,
Parity, Stop Bits, Flow Control, Read Mode, Protocol, Tag Block Size, DIP1, Direct Read, Single
Mode Timeout, Start and End Characters, UART Settings. Any changes to these sections that are a
part of the Config App require the icon “Send Config”to be pressed and the Reader to be re-powered.
Operations App (Run) - and Run options are what operate the Reader, Connect, Disconnect, Scan
Ports, Get Config, Send Config, Read Block, Write Block, GroupBox 1, Block Number, Data to
Write, Data In and Data Counter, although the latter 4 are white in color. You can make changes to
any of the Run App selections, but they will not be held in non-volatile memory. For example, if you
have the Read Mode (Config) set to Single and you change the GroupBox 1 (Run) to Duplicate Read
Mode, this latter setting will not be held in non-volatile memory, meaning if you re-power the Reader
it will revert to the setting of the Config, that being Single Read Mode.

DIP1 Section (Config)
Left unchecked, the ASCII box will leave the Reader operating in hexadecimal values, offering only
characters of 0-9 and A-F. When checked, you will be able to program and read Tags in ASCII, for
example with the data John Q. Smith. It should be noted, that if you change from hexadecimal to
ASCII or vice versa, a Tag will have to be re-programmed in order to be read. Also note that in
ASCII you will have half the characters available, 8 characters per block versus 16 characters when
using hexadecimal.
The LED Blink option allows for the change to blinking LED’s on the Reader when a Tag is
presented. Left unchecked, the LED’s will remain solid.
Direct Read Section (Config)
Default is for Direct Read Disabled, which enables the Reader to read only the UID section of Tag
memory. Set the selection to Direct Read in order to read a specific block or blocks of data in
extended memory by default. You could further choose Start Address as 01 and Byte Count to 8 to
read the first block of data, or Byte Count to 16 to read the read the first two blocks of data. However,
you can always manually read a single block by entering the Block# located at bottom right of
program and selecting “Read Block.”
Single Mode Timeout (Config)
This setting determines the amount of time a Tag must be absent from the Reader before being able to
be read and reported again. A setting of 2000 = 2 seconds. If you read a Tag and remove it from the
Reader for 1 second and re-present the Tag, it will not read again although the yellow LED will
become active. If you remove the Tag and re-present after 2 seconds, it will read and report again.
The minimum allowable setting is 100ms.
Start and End Characters (Config)
These are settings for the structure of Reader outputs of messages or Tag data. Normally we use LF
as start and CR as end of message. These can be turned off by setting to 00, or changed to
Data+CRLF by setting start to 00 and End 1 to CR and End 2 to LF, or changed to DATA+CR by
setting Start to 00 and End 1 to CR and End 2 to 00. The default is Start = LF, End 1 = CR, End 2 =
00 equating to an output of <LF>DATA<CR>.
UART Settings (Config)
Obviously these are the Data Bits, Parity and Stop Bits settings.
Reading Modes
In addition to the green LED on the Reader indicating power is applied, a yellow LED will appear
while a Tag is present to the Reader. You can change the Read Mode by selecting Single, Duplicate
or Polling. Notice that as you do so, the message OK will fill into Data In field.
Single Read Mode - will read a Tag one time upon presentation to the Reader and will timeout based
on the Single Mode Timeout setting. That timeout sequence begins only after a Tag is removed from
the Reader, meaning if a Tag is set upon the Reader for an indefinite period of time, it will never be
read a second time. Presentation of a second Tag would be immediately reported and the timeout
sequence begun anew.

Duplicate Read Mode –will continually read and report a Tag, a nice tool for read range and read
window testing. The number of times a Tag is read will be shown in the Data In Counter field.
Polling Read Mode –will read and report a Tag only when commanded using the “Poll [T]”option,
although the yellow LED will still illuminate as long as a Tag is present to the Reader.
Get Config
When you select Get Config this will show all the Reader’s current settings in the Data In field. Some
may be unintelligible to the user, but here is an example.
S,07,ALL PROTOCOLS,08,0,8,FF,00,0A,0D,00,2000
S = Read Mode
07 = DIP1 (115200 Baud Rate)
ALL PROTOCOLS = Tag chips able to be read
08 = Block Size
0 = Start Address
8 = Number of bytes
FF = Direct USER memory Read Disabled (55=Enabled)
00 = UART Bits (Parity, data bits, etc.)
0A = Start char
0D = End char 1
00 = End char 2
2000 = Single mode timeout

Using a Terminal Program & ASCII commands
If you prefer, any common terminal emulation program can be used, for example HyperTerminal,
ProComm, Teraterm, Putty, etc. If you have already interfaced the Reader to a terminal program or
your own software, upon powering the Reader you will see a power up message. You can then use
the ASCII Reader commands shown in Section 3 Operating the Reader.
RFID, Inc.’s free of charge Terminal Program - RFID, Inc. provides a free software demo program
called “RFID Demo Terminal Program”downloadable here https://www.rfidinc.com/resource-center/.
It may appear in your Programs menu as RFIDIncUHFTerm. It is important to follow these steps in
order for the program to scan and identify the ports available on your computer.
(1) Plug the RS232 9 pin connector into your computer (use an RS232 to USB converter if no 9 pin
connector is available on your computer).
(2) Power the Reader.
(3) Execute the RFIDIncUHFTerm Program. Select “Scan Ports” found upper right. This allows the
program to scan which port address is connected to the Reader. In the upper left, under “Ports” use
the pulldown menu to choose the port discovered.
(4) Set the baud rate and remaining communication settings, default is 115200 baud, 8 data bits, None
Parity, 1 stop bit and None Flow Control (115200, 8, N, 1, N). You can also view which port is
connected by going to your Desktop, right click on My Computer, choose Properties, Hardware and
Device Manager, then open the Ports directory tree.
(5) Select “Connect.” Presenting a Tag to the Antenna should now bring that Tag data onto the main
screen and the lower body of the screen as well.
Remove Old Data - This program also offers the ability to “Remove Old Data” by checking this box
under “Tag Read Settings,” a process of deleting Tag reads from the screen set to the timeouts you
choose in the pull down menu. For example if you choose 5,10,15 Timeout, Tag data will begin
highlighted in green for the first 5 seconds, then become highlighted in yellow at 5 seconds time, then
turn to red at 10 seconds time, and finally be deleted at 15 seconds time.
Maximum Tags –An option rarely used for HF Tags. This program also offers the ability to time
how long it takes to read the amount of Tags you wish to test by choosing the number of Tags under
the “Max Tags” setting. You will see the data field to the right increment as the Reader counts how
many unique Tags have been read. If you choose 100 as your Max Tags setting, once the Reader has
read 100 unique Tags a pop up box will appear advising you the amount of time this procedure took.
Save –This box will prompt you to save Tag data to a text file with time and date stamp.
The main screen area (white) is solely used for display of Tag data. The lower screen area (black)
will display Tag data and also allow you to enter commands to the Reader. Note - All commands

must be issued in CAPS, preceded by an open square bracket and ended with a closed square bracket
[B] for example. There is more in depth information on how to read and write specific portions of
Tag memory under the Commands section of this product manual.
Single Report Tag Read Mode –Place your cursor in the lower screen area and type [S]. This will
initiate the Single Report Tag Read Mode and the Reader will respond with “OK.”
Duplicate Report Tag Read Mode - Place your cursor in the lower screen area and type [D]. This will
initiate the Duplicate Report Tag Read Mode and the Reader will respond with “OK.”
Section 3 - Operating the Reader
This section explains operational commands and input received back from the Reader, commands,
operating modes, and responses.
Note:
All commands are issued in ASCII CAPITAL letters, and they are preceded by an open square
bracket and ended with a closed square bracket. Some symbols and all numbers are permitted.
No spaces are permitted.
Commands are held in non-volatile memory, meaning that if power is taken away from the Smart
Antenna the last command or settings will be retained when re-powered.

General Commands & Responses (ISO protocol independent)
Tag Data Delivery
Tag data will be sent to the serial port in the following format.
<LF>XXXXXXXX<CR>
Where: <LF> = Line Feed
XXXXXXXX = Tag data
<CR> = Carriage Return
Single Mode Command - [S]
This command causes the reader to enter SINGLE MODE. In this mode the reader will only
report the Tag ID once when it arrives within antenna range. The Reader continues to read the
ID but does not report it again. As long as a Tag is continually present to the Reader only 1
read will be reported however if the Tag leaves the Reader’s RF field briefly and is re-presented
the read will be re-reported.
Host: [S]
Where: S= command
Reader Response: <LF>OK<CR>
Where: <LF> = Line Feed
OK = Response
<CR> = Carriage Return
Duplicate Mode Command - [D]
This command causes the reader to enter DUPLICATE MODE. In this mode the Reader will
continually report any Tag ID present to the Reader. This mode is mostly used as a test or
demonstration mode to visually measure read range.
Host: [D]
Where: D= command
Reader Response: <LF>OK<CR>
Where: <LF> = Line Feed
OK = Response
<CR> = Carriage Return
Polling Mode Command - [P]
This command causes the transponder to enter POLLING MODE. In this mode the Reader
does not capture Tag IDs automatically; the user must use the ‘T’ Transfer command to request
an ID to be captured.
Host: [P]
Where: P= command

[6sbehel] –Start and End Settings
sb = start byte
eh = End byte High or first end byte
el = End byte low or second end byte
Examples:
[6000D0A] Start disabled. END 1 = CR END 2 = LF. tag data in this format: 12345678CRLF
[60A0D00] Start = LF, END 1 = CR, END 2 = disabled. Tag data in this format:
LF12345678CR
[6000D00] Start disabled, END 1 = CR, END 2 disabled. Tag data in this format: 12345678CR
[7x] –Select Hexadecimal or ASCII Format
Select hex (raw) or ASCII format.
1 = ASCII
0 = hex (RAW)
Let’s assume a tag block of 4 bytes is programed like this.
Byte 1 = 0x30, byte 2 = 0x31, byte 3 = 0x32, byte 4 = 0x33
If ASCII is enabled [71]
Tag will be reported as 0123 (Humana uses ASCII)
If RAW is enabled [70]
Tag will be reported as 30313233.
[B] –Change Tag ISO Protocol
Change tag protocol, every time you enter [B] you advance to the next protocol, or command
directly using [Bx].
[Bx] –Change Tag ISO Protocol Directly or View Current Setting
[B?] Returns current protocol
[B1] NFC-A ISO14443A
[B2] NFC-B ISO14443B
[B3] NFC-F FeliCa
[B4] NFC-V ISO15693
[B5] ST25TB04K
[ERS] –Reset to Factory Defaults
Erases all EEPROM returning reader to factory defaults.

xx = a hexadecimal value to write to the deep-switch EEPROM byte
Bit 7 NOT USED - Leave as 0
Bit 6 ASCII EN - It is set or cleared by the command [7x]
1 = ASCII MODE enabled
0 = ASCII MODE disabled
Bit 5 BLINK EN - Set or cleared by the command [LEDx]
1 = SYSTEM LED BLINK on read enabled
0 = SYSTEM LED BLINK on read disabled
Bit 4 NOT USED - Leave as 0
Bit 3 NOT USED - Leave as 0
Bits 2 to 0 - Baud Rate settings
[V] –View Current Settings
Returns current settings. Protocol, Read Mode, Virtual DIP Switches.
Error Messages
? –Invalid Command
e –no read or Tag present
FAILED –Write fail
These messages follow the same formatting as tag data. The ‘?’ – Invalid command message
indicates that the device detected a problem with the last command issued. The invalid command
message is issued upon reception of the end of message delimiter when one of the following errors
has been detected:
No command between delimiters –the receipt of a start and end delimiters without a command.
Illegal command between delimiters –the receipt of a message not contained within this
specification.
Legal but invalid command received –i.e. the receipt of [T] Transfer/read request while not in
MODE Polling.

Tag Memory
Generally, HF RFID passive Tag chips, containing a EEPROM with encoded data, have no finite life
for read only operations and a finite life of 100k writes. There exists a plethora of HF Tag chips
available on the market, thus Tag memory is not discussed in detail herein. RFID, Inc. can provide a
specific memory organization map dependent upon the chip and size of memory you intend to use.
ISO15693
The Tag UID is 64 bits long (8 bytes), represented by 16 hexadecimal characters. Example
<LF>E0078077CDCD153E<CR>.
Most ISO15693 transponders are divided in blocks of 4 bytes (32 bits) represented by 8 hexadecimal
characters. Example <LF>05 00000578<CR>.
In some very rare cases an ISO15693 transponder will be divided in blocks of 64 bits. The reader
automatically recognizes these types of Tags and adjusts its data size accordingly. If you are not
familiar with the block size of the Tag in use, it is recommended to read a block from it to discover
the block size.
ISO14443-B
The Transponder ID is 32 bits long (4 bytes). Example <LF>008B78B5<CR>
Tag memory is divided in pages of 8 bytes (64 bits) represented by 16 hexadecimal characters. When
reading a page the reader first sends the two digit page number followed by a space and the 16
characters of data. Example <LF>05 0000000000000056<CR>.
Here are some examples of memory sizes available. With new chips being added to the market from
time to time, this list may not be up to date.

Troubleshooting
My Reader is not responding.
Re-power the unit. Ensure the LED is on indicating power is applied? If not, check the source
of your supply (change AC outlets or power supplies).
The LED is on but does not blink when a Tag is presented.
Ensure the Reader is in the correct Tag Mode specific to your specific ISO Tags, for example
15693. Change the Tag Mode using the [B] command.
The LED is comes solid or blinks when a Tag is presented but I see no data on my PC.
Ensure communications are established by re-powering the Reader (RS232 only) and looking
for a startup message or enter an invalid command which should bring the response of a
question mark (?). If you do not see these occur, there is an issue with communications not be
properly established. Ensure your COM port is addressed correctly if using HyperTerminal.
The Reader returns a question mark (?)
The command you are attempting is not being entered correctly. Ensure you use open square
bracket, capital letters, and close square bracket.
