Function
II Function
Basically, the reader works in a continuous read mode. In this mode the green LED is always on.
At power up or after restart (use the restart button) the reader can read a configuration transponder to
get new settings. After reading the new configuration, the reader goes into normal operation mode.
Whenever a transponder appears, the reader reads its level and wedge information out of the
transponder. If the level and wedge number is the same as stored in its configuration block the drop
(relay 1) will be switched on and the red LED turns on, otherwise the no drop (relay 2) will be switched
on and the yellow LED turns on.
IMPORTANT: The antenna is integrated in the center of the upper shell of the housing. The
best read range is achieved, when the glass transponder points to antenna.

Reader Configuration
III Reader Configuration
At power up or after reset the reader tries to read for a fixed duration of 5 seconds the configuration page
of the transponder. If there is a valid block (checksum ok), the reader stores the configuration in its non
volatile memory.
There are 8 configuration bytes.
Table:
CFG0 operating mode
CFG1 lane full trigger time or read trigger time (depends on operating mode)
CFG2 lane free trigger time or read error time (depends on operating mode)
CFG3 relay 1/2 delay time
CFG4 relay 1/2 on time

CFG1
LANE_FULL_TRIGGER_TIME (if lane full sensor enabled, bit 4 operating mode = 0)
Description:
This byte specifies the valid trigger time for the lane full sensor (input 3). If the senor is active for a
LANE_FULL_TRIGGER_TIME period, the lane full (relay 3) will be turned on. If so, each
transponder, valid or not, activates the no drop (relay 2) function. Valid values are 0 to 255. That
means the lane full trigger time can range between 0 and 25.5 seconds.
TRIGGER_TIME (if trigger selected , bit 0 operating mode = 1)
Description:
This byte specifies the valid trigger time. If the trigger mode is enabled and an external trigger
signal occurs (input 1) the trigger timer starts. Within the TRIGGER_TIME a wedge transponder
(valid or not valid) must be read, otherwise the error output will be set as specified in the
OPERATING_MODE. Valid values are 0 to 255. That means the trigger time can range between 0
and 25.5 seconds.
In trigger mode the green LED flashes if the reader starts the read cycle.
CFG2
LANE_FREE_TIME (if lane full sensor enabled, bit 4 operating mode = 0)
Description:
This byte specifies the valid trigger time where the lane full sensor must be inactive, to turn off the
lane full (relay 3) function. After this, a valid transponder activates the drop (relay 1) function.
Valid values are 0 to 255. That means the err time can range between 0 and 25.5 seconds.
ERR_TIME (if trigger and err time selected)
Description:
This byte specifies the err time x 100 milliseconds for the error output signal (internal buzzer and
relay 4). The output will be set if an error occurs.
Valid values are 0 to 255. That means the err time can range between 0 and 25.5 seconds.
CFG3
RELAY_DELAY_TIME
Description:
This byte specifies the relay delay time x 100 milliseconds for a wedge number.
Valid values are 0 to 255. That means the delay time can range between 0 and 25.5 seconds.
The delay time will be used for the drop (relay 1) and no drop (relay 2) function.
NOTE:
If the relay delay timer is running, no new wedge transponder will be read!
DTE Automation GmbH
Version 2.2 Page 9
CFG4
RELAY_ON_TIME
Description:
This byte specifies the relay on time x 100 milliseconds for a wedge number after the delay time
has reached. Valid values are 0 to 255. That means the relay on time can range between 0 and
25.5 seconds. If the relay on time is equal 0, the relay on function is disabled.
The relay on time will be used for the drop (relay 1) and no drop (relay 2) function.
CFG5
LEVEL_NUMBER
Description:
This byte specifies the level number of the reader. The level value can range from 0 to 128.
Level 0 means the wedge function is disabled.
CFG6
WEDGE_NUMBER
Description:
This byte specifies the wedge number of the reader. The Wedge value can range from 0 to 255.
Wedge 0 means the wedge function is disabled.
CFG7
CHECKSUM
Description:
This byte is the checksum for the above configuration bytes. It must be valid, otherwise the reader
ignores the new configuration information. The checksum is calculated as follows:
CFG7 = NEG (CFG0 XOR CFG1 XOR CFG2 XOR CFG3 XOR CFG4 XOR CFG5 XOR CFG6)
DTE Automation GmbH
Version 2.2 Page 10
Protocol
V Protocol
Basically, the protocol in the Reader works in a polling mode.
It is necessary to give a level and a wedge number to each Wedge Reader.
Level number: 1.....128
Wedge number: 1…255
This lets the PC manage more than one Wedge Reader at one serial port. The PC 'polls', which means
the PC sends messages to all the readers that are connected to the serial port, one after another.
It is also possible to start a GENERAL POLL. Level number 0 and Wedge number 0 are dedicated to
this feature. If, for example, the PC polls for the Level 0 / Wedge 0, every reader answers this call.
Several readers answering at the same time will cause a data collision on the BUS. The PC will
recognise this, and by special polling, be able to identify a specific Wedge Reader.
The serial port of the PC is used for transmitting data to the Wedge Reader unit. Usually this would be
COM1.
Parameters for the transmission are fixed to:
Baud Rate: 9600
Start Bit: 1
Data Bits: 8
Parity Bit: none
Stop Bits: 1
Interface to reader unit
The integrated signal converter can generate serial RS232 or RS422 level.
It can be changed with two jumpers. For more information contact our technical support.
Features
The number of net data bytes per second, compared with the protocol overhead, depends on the data
size of the command.
The typical reader reply time for a polling call is about 1 msec.
Only if the stand alone mode is disabled and no tag read or write command will be used.
Typ. Reply Time: 1 msec
Type Of Protocol: POLLING
Transmission Security Per Byte: none
Transmission Security Per Block: BCC (EXOR)

Protocol Syntax
VI Protocol Syntax
The basic principle for communication is that the PC is always the MASTER, the Wedge Reader is
always the SLAVE. Every action is initiated by the PC. This is required by the polling mode.
There are COMMANDS from the PC to the reader and there are REPLIES from the reader to the PC.
COMMANDS and REPLIES consist of HEADER, DATA and END part. The HEADER is always the
same for all COMMANDS and REPLIES. The length of the transmitted DATA is coded in the HEADER.
If, in the following description, some parameters are not named, the parameter will not be evaluated by
the reader.
