Ha-VIS RFID RF-R400 – System Manual
Introduction
4. Introduction
4.1 The UHF Long Range Readers Ha-VIS RFID RF-R400
The Ha-VIS RFID RF-R400 is a Long Range Reader version of the UHF product line.
The RF-R400 closes the gap between the RF-R500 high performance long range readers and
the RF-R3x0 mid range reader family. It has the following key features:
• Low noise transmitter architecture
• High sensitivity receiver increases the tag detection range so that transponders can be read
over the entire power up, eld strength area.
• Reader protection against various fault conditions as e.g. antenna shortcut, antenna
mismatching and electrostatic discharge.
• Tough, solid aluminium die case housing for rough environments.
• Quick installation due to easy access to the interfaces and antenna ports.
• Indication of read events via 4 separate reading point LEDs.
• Various I/Os suit industrial needs
• Robust M12 and M8 connectors
• following the EN50155
• very good temperature operating range
The base set of commands and features are compatible with the commands used throughout
the product line. The conguration possibilities of the Ha-VIS RFID RF-R400 make it easy to
adapt the reader to a wide range of applications by software and hardware congurations.
The reader has three hardware interface ports: Ethernet, RS232 and USB. Furthermore, the
reader has digital I/O’s for direct control of various trigger possibilities and various outputs for a
direct control of several indi-cators.

Ha-VIS RFID RF-R400 – System Manual
5. Data Transmission between Ha-VIS RFID RF-R400 and Host
Six different ways of data transmission between RF-R400 and host (terminal, PC) are possible.
The Host Commands, Buffered Read Mode, Scan Mode and Notication Mode are used
for the data exchange between transponder and host, whereas the Conguration Commands
and the Reader Control Commands serves for adapting the reader parameters to the
individual range of applications. The following chart shows which method of data transmission
is supported by which interface:
Interface
RS232 LAN USB*
Conguration Commands PPP
Reader Control Commands PPP
Host Commands PPP
Buffered Read Mode PPP
Scan Mode PO O
Notication Mode OPO
*just for testing not recommended for real applications
5.1 Conguration Commands and Control Commands
This method of data transmission is used for Reader conguration and the diagnosis via the
different Hardware Interfaces of the reader.
The reader-conguration parameters will be stored in the Reader memory. To store the current
conguration during a power down of the reader the reader-Conguration has to be stored in
the EEPROM. After power up the reader reads the conguration out of the EEPROM.
The reader control is immediately processed and the response from the Reader contains status
or data information of the control command.
Host (Terminal / PC / ....) Reader
parameter- / control command àparameter received and stored / control

yes no
ßstatus /

ßerror status
5.2 Host Commands
The host commands provide the exchange of data between a host and transponders via the
reader as long as the transponder remains in the detection range of the reader.
Note
During the writing of data to a transponder, it must be ensured that the transponder is located
within the detection range of the reader for the duration of the entire process. If the transponder
is removed from detection range of the reader during a writing process, this will cause a loss of
data.

13
Ha-VIS RFID RF-R400 – System Manual
Data Transmission between Ha-VIS RFID RF-R400 and Host
The reader to transponder addressing mode:
Addressed mode:
Before reading or writing data in addressed mode, the UID of the transponder has to be known.
This is executed by sending the protocol 10.1.1 [0x01] Inventory. If a transponder is located
within the detection range of the reader at that time, it answers with its UID. For all following
read- / write orders the transponder must be addressed with its correct UID. The following chart
will show the necessary steps for the communication with a transponder in addressed mode:
Host (Terminal / PC / ....) Reader

write data to transponder with UID àtransponder with correct UID in antenna eld?
yes no
ßOK status
ßstatus =
no transponder in reader eld
5.3 Buffered Read Mode
The Buffered Read Mode is a high level operating mode to detect transponders which are
within the detection range of the reader. This operation mode processes all transponder read
data and lter operations to make the user interface transparent to transponder data and to
minimize data transfers between reader and host. There are only three commands used to
control Buffered Read Mode.
In this operating mode the reader automatically selects transponders which are within the
detection range of the reader and reads their requested data. The read transponder data is
stored in a ‘FIFO’ organized data buffer. Up to 1700 can be stored into the buffer. In case of
power down the buffer will be initialized and all datasets get lost.
The sampled transponder data can be read with the 11.4 [0x22] Read Buffer command. This
command always reads the rst available data sets from the data buffer. However data already
read have to be deleted with the 11.6 [0x32] Clear Data Buffer command before the next data
sets in the data buffer can be reached with the read command.
If the Buffered Read Mode is enabled in the 7.2 CFG1: Interface and Mode conguration block
the reader immediately starts sampling transponder data after power up. The Buffered Read
Mode can be reinitialized with the 11.7 [0x33] Initialize Buffer command.
If turned to Buffered Read Mode the reader answers every valid message with data- or status-
protocol. The answer includes the control byte which has been received by the reader.

Note
Only read operations are available with the Buffered Read Mode.
5.4 Notication Mode
The Notication Mode is an extended option of the Buffered Read Mode: queued transponder
data and optionally Input / status events are notied automatically and asynchronously to a
host with the 11. Protocols for Buffered Read Mode and Notification Mode response protocol.
The destination address and the notication conditions can be set in 7.24 CFG49: Notification
Channel conguration block. In general, the notication channel can be used simultaneously
with the host interface.
In difference to the Buffered Read Mode procedure, a notication is normally not acknowledged
by the host. Thus, the deletion of the transferred data with the 11.6 [0x32] Clear Data Buffer
command is not necessary. As an option, the acknowledgement can be enabled to synchronize
the notications with the host to prevent notication overow in the host application.
The notication message format depends on trigger settings in 7.9 CFG10: Trigger and settings
for the read mode in 7.10 CFG11: Read Mode – Read Data and 7.11 CFG12: Read Mode -
Filter as well as settings for the notication trigger in 7.24 CFG49: Notification Channel. The
following table lists the message formats:
Notication Trigger: continuous or time-triggered
Input/Status Event Data Event
Read Trigger disabled Input/Status and Data Events are notied together in one or multiple
messages.
The message format depends on settings in TR-DATA of CFG11.
Read Trigger enabled Notication separately and
immediately, if in:
CFG11: IN ag in TR-DATA2 is set
and
CFG12: ag is set for input and/or
status to be observed
Notication shortly after notication
of input/status event.
The message format depends on
settings in TR-DATA of CFG11.
Note
One notication can contain more than one input/status event, if multiple events occur at the
same time.

15
Ha-VIS RFID RF-R400 – System Manual
Data Transmission between Ha-VIS RFID RF-R400 and Host
Notication Trigger: host-triggered
Input/Status Event Data Event
Independent of Read Trigger Input/Status and Data Events are notied together in one message. The
notication is activated by command [0x34] Force Notify Trigger.
The message format depends on settings in TR-DATA of CFG11.
An additional option of the Notication Mode is the keepalive message, which can be sent
periodically to the host. The keepalive message transports valuable information about
the reader hardware and antenna tuning status. Keepalive messages are always never
acknowledged by the host. The keepalive message should not be mistaken with the keepalive
option of a LAN connection initiated by a host.
5.5 Scan Mode
In this operation mode the reader autonomously sends out data to the Host as soon as a
transponder is within the detection range and valid data could be read.
In Scan Mode the contents of the message block (UID, data block) can be adapted to each
user-application. Scan mode is available via the asynchronous Interface.
The reader starts the output of the protocol block as soon as all required data have been read
correctly from the transponder. If the reader is not able to read all data of a protocol block
completely and without error, it does not send data. For example, if the address of the data
block is invalid, the UID of the transponder will not be sent out.
5.5.1 Scan Mode via asynchronous interface:
The data will be sent out depending on their conguration according to the following scheme,
the sequence of which cannot be changed.
Depending to the conguration and the number of transponders in the detection range of the
reader the transmitted protocols have a different format.
Example 1:
One transponder in detection range and UID and data block should be read:
PR UID SC data EC PR UID
protocol block ts+ tr
protocol cycle
Example 2:
Three transponders in detection range only UID should be read:
PR UID1 EC UID2 EC UID3 EC
Example 3:
Three transponders in detection range only data block should be read
PR data1 EC data2 EC data3 EC

16 HARTING IT Software Development GmbH & Co. KG
Ha-VIS RFID RF-R400 – System Manual
Example 4:
Two transponders in detection range UID and data block should be read
PR UID1 SC data1 EC UID2 SC data2 EC
PR: Com-Prex (optional) ts: SCAN-LOCK-TIME
UID: Serial-Number (x) tr: time to the next new transponder reading
data: data blocks (free programmable)
SC Separation character (optional)
EC End character (optional)
Note
If conguration protocols shall be sent to the Reader while the Scan Mode is active, no
Transponder should be within the detection range of the Reader during this time.
Only read operations are available with the Scan Mode.

Interface
6. Interface
The Ha-VIS RFID RF-R400 has 3 interface ports. The protocol frame of these ports can be
different. On the asynchronous serial interface the whole protocol frame is described in 6.2.
Serial Data Format and Protocol Frames. The TCP/IP protocol frame is described below.
6.1 Characteristics of TCP/IP protocol
If the Reader uses the LAN interface the data is packaged in TCP/IP protocol frames. This
means the whole data format and protocol frame which is described in 6.2. Serial Data Format
and Protocol Frames is packaged as the data of TCP/IP protocol frames.
If you use the TCP/IP protocol please be aware that the data packaged in the TCP/IP frame is
transferred with Protocol frame: Advanced Protocol-Length as describe below.
The LAN socket on the reader side uses the keepalive option for detecting interrupted
connections. The default parameters for keepalive are initialized as listed in the table:
Parameter Value Note
idle time 5 seconds The reader sends every 5 seconds a keepalive probe which
has to be acknowledged by the client
repeat count 2 If a keepalive probe is not acknowledged, the reader repeats
the probe only two times with an interval of 5 seconds.
interval 5 second
If the 15 second time span is expired and no keepalive probe response is obtained from the
client the connection is closed and the client application must enable a new connection. The
keepalive parameters can be modied in the conguration pages for LAN. This keepalive option
should not be mistake with the Keepalive message for notication mode.
6.2 Serial Data Format and Protocol Frames
The Ha-VIS RF-R400 can be congured by different interfaces and data may be written on
transponders or read from sransponders. The communication between deader and connected
host (terminal, PC, etc.) is executed by means of xed protocols. The used protocol is intended
for data bus use and is equipped with a bus address.
During data transfer via the asynchronous interface the deader supplies the required data or a
status byte. The reply contains the transmitted control byte.
There is no reply from the deader if there is a protocol frame failure.

The Reader supports the advanced protocol frame only.
STX: If the responded protocol of the Reader starts with the STX
sign (0x02) the protocol includes more than 255 Byte. Then the
protocol length is dened by the 2 Byte Parameter ALENGTH.

7. Conguration Parameters
The conguration memory of the Reader is organized in conguration blocks of 16 byte each.
These are divided into 14 byte conguration parameters and a 2 byte CRC16 checksum. Each
of these conguration blocks takes a number (CFG 0...CFG n).
Structure of a conguration block in Reader conguration memory and Reader EEPROM
(CFG):
Byte 01234567891011 12 13 14 15
Contents PARAMETER CRC16
The parameters are stored in two different conguration memory locations:
• Reader RAMx
• Backup EEPROM (used for storing parameter over power down)
Multiple conguration memory locations can be addressed by the value of the parameter CFG-ADR.
CFG-ADR:
CFGn memory-address of the required conguration block
LOC: species the location of the conguration block (RAM / EEPROM)
MODE: species one or all conguration blocks
Bit 76543210
Function LOC Mode CFGn: address of conguration block
The EEPROM conguration blocks are protected by a 16 bit CRC-checksum. The examination
of these checksums is executed after each reset of the Reader. If a checksum error is found,
the Reader goes into an error status „EE-Init-Mode“ and sets the conguration block which is
faulty to the default-values.
While the EE-Init-Mode is active, the LED blinks alternately red and green and the Reader
answers external commands with the status „0x10 EEPROM Failure“. The „EE-Init-Mode“ can
be exited now by a new reset (cold start or 9.3 [0x64] System Reset command). If after this the
checksums of all data records are correct, the Reader shifts to the congured operation mode.
Note
Malfunctions may occur if parameters are congured outside their described range or if
unspecied parameters have been changed!
A downgrade of the rmware will result in a complete reset of the EEPROM. All parameters will
be reset to factory default.
