ASR700 Reader Operation
2.3 Operation
2.3.1 Basic settings
The ASR700 reader comes preset with a factory configuration. Following installation of the
reader and an antenna, and the reader has been tuned; the reader is ready for operation in
combination with suitable application software.
reader and an antenna, and the reader has been tuned; the reader is ready for operation in
combination with suitable application software.
2.3.2 First-time use of the ASR700 – an example
Requirements:
• The power supply is connected
• The RS232 interface is selected
• An antenna has been connected and tuned
Objective:
To set the so-called master mode. This is a read mode in which the RF field is permanently ac-
tivated. As soon as a transponder is detected, an ID message is put out by the specified inter-
face.
Start–up:
Once the RS232 interface has been connected to one of the serial interfaces of the computer
(COM1, COM2,…), start the demo software Asrdemo.exe that should already be installed on
the computer.
For more detailed information on Asrdemo.exe please refer to the corresponding manual.

2.3.3 Read function
Once the read function has been activated (different operating modes) a transponder brought
into the detection area is quickly registered.
Note that the following factors may reduce the reading range:
• Alignment of the transponder to the antenna: the transponder axis (disk transponder: central
into the detection area is quickly registered.
Note that the following factors may reduce the reading range:
• Alignment of the transponder to the antenna: the transponder axis (disk transponder: central
axis standing vertically on the plane of the circular face; glass transponder: longitudinal axis
corresponds to the central axis) is parallel to the antenna axis (corresponds to the central
axis standing vertically on the antenna surface); the larger the angel between transponder
and antenna axis, the shorter the range will be.

• Temperature range / environmental conditions: best results will be achieved within the tem-
perature range approved for operation and the environmental conditions described in chap-

• Installing the transponder on metal surfaces can have a negative effect on the read distance.
• Size of the transponder: the larger the transponder the larger the read distance with the sa-
• Size of the transponder: the larger the transponder the larger the read distance with the sa-
me reader.
• Running multiple RFID systems simultaneously: these can be sources of interference for
each other.
Important! Please note that there should be no more than one transponder of the same type in
the detection area of the reader at any time since multiple transponders of the same type can
under certain circumstances make reliable detection impossible. Also avoid the simultaneous
presence of two different transponders in off mode (see chapter 1, register Cfg_Format) since
this could lead to problems with processing the transponder data.
2.3.4 Displaying the read function
The ASR700 confirms when a transponder has been read successfully by giving a visual signal:
the green LED (Read LED, see chapter 2.2.1) on the top of the housing lights up for a short
time.
