Orientation of magnetic fields of the SIMATIC RF382R Scanmode
For many applications it may be best to operate the reader so that the tags move from left to right (or from right to left) at a
certain distance in front of the narrow edge of the reader. This direction of movement uses the horizontal magnetic field of
the reader, see figure below.
You also have the option of moving the tags up and down (or down and up) past the narrow edge of the reader. This
direction of movement uses the vertical magnetic field of the reader.

Figure 1 Definition of horizontal and vertical magnetic reader field
Maximum magnetic field strength
The reader creates the maximum magnetic field about 13 mm below the upper reader edge. For the largest possible reading
range the tags you want to read should move in this range. This applies whether you use the horizontal or the vertical
magnetic field.

The area of the maximum field strength and, therefore, the maximum range is identified by a laser icon:

Note
Tips if the range is too short
If the range of the antenna is too short, you must check
● the power supply/switched-mode power supply (interference)
● whether there are monitors or other sources of interference nearby
● whether there is metal in the environment

NOTICE
Extension of the data transmission time if distance values are undershot
If the distance values specified in the tables are undershot, it is possible that the inductive fields will be affected. The time
required for data transmission can increase unpredictably.
For this reason, please observe the values in the tables.

Setting the parameters of the RF382R
Certain parameters of the scan mode can be changed during operation. These parameters are transferred from the host to
the reader via the serial interface for this purpose.
You can change the following parameters this way:
● ScanMode: Single Read (single reading of a tag) or Continuous Read (continuous reading of a tag)
● LockTime: Lock time for the setting "Continuous Read"
● Retentive: The parameters are stored in the non-volatile Flash memory of the reader.
The interface parameters for transfer are set permanently to 38400, 8, n, 1. This data sequence can be easily integrated into
an existing application because the parameter assignment frame is open.
Structure of the parameter assignment frame to the reader
You can transfer a new parameter set to the reader at any time during operation. When a parameter set is received, scan
mode will be interrupted, and the new parameters are checked and adopted if they are found to be "good". Scan mode will
start up immediately once the parameters have been accepted.
Note
Data will be lost during parameter setting (which means from receipt of a parameter frame until acknowledgment) if
operation continues.
The parameters are either saved in RAM (status = 00) only or retentively (status = 01). The command for transmission of
parameters ("Para") is 01.
Data backup takes place with a simple EXOR operation (BCC) of all data bytes to be transferred.
The parameters will be transferred as a data sequence (message frame). The following parameters can be modified:
● "LockTime" parameter; you can set values of 0..65535 (time base 100 ms)
● "ScanMode" parameter; you can set ContinousRead (00) and SingleRead (01)
All the other parameter bytes are reserved for future use and have to be assigned with 0.

Error code BCC
The acknowledgment message frame consists of three bytes. The acknowledgment byte is identical to the command byte.
The error code is zero if the parameters are accepted without errors. An error code other than zero means that the
parameters have not been accepted. The following error codes are defined:
01 The command byte is incorrect (only "Para" is permitted)
02 The status byte is incorrect (RAM or retentive only)
03 The Scanmode parameter is incorrect (ContinousRead and SingleRead permitted only)
04 The BCC value in the parameter message frame is incorrect.
05 Data could not be saved retentively (error with Flash type request)
06 Data could not be saved retentively (error with Flash delete)
07 Data could not be saved retentively (error with Flash writing)
