ANT D2
3.4 Field data for MDS and SLG
For more information on the transfer window, refer to Chapter Transmission window
(Page 19).
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
Minimum distance from MDS to MDS (without multitag mode)
Table 3- 4
Horizontal main field
Vertical main field
The minimum distance can be undershot in multitag mode. (SLG D10/SLG D11/SLG D12,
RS 232).
Minimum distance from SLG to SLG (antennas)
In the following table, the minimum distances between different SLGs and the SLG
D11/D11S with ANT D2 are defined:
Table 3- 5 Minimum distance between SLG D11/D11S with ANT D2 and other SLGs (antennas)
SLG D11 ANT D2
SLG D11S ANT D2
≥ 0.5 m
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. In this case, the data transmission time can increase unpredictably or
a command is aborted with an error.
For this reason, please observe the values in the tables.
