Note: This parameter is intended for trained users. Siemens recommends that
untrained users use the default value.
Readers of the 1st generation: With this parameter you can change the transmit
power (output power) of the RF380R reader of the 1st generation (6GT2801-
3AB10). When doing this, remember that the change to the transmit power will
affect the detection in the limit range (upper/lower operating distance), as well as
the minimum distance that is to be maintained between adjacent RF380Rs.
Settings outside the specified range have the effect that the default value (1.25 W)
will be set. In this case, for reasons of compatibility, there is no error message.
Readers of the 2nd generation: This setting is not necessary with the RF380R
readers of the 2nd generation (6GT2801-3BAx0) because the power limits are
optimized automatically depending on the reader-transponder distance. For rea-
sons of compatibility, this setting can nevertheless be made. Note that the values
"0x02", "0x03" and "0x04" bring about a reduction of the power of approximately
50%.
The following settings are possible:
Value
Transmit power
0x02
0.5 W
0x03
0.75 W
0x04
1.0 W
0x05
1.25 W (default)
0x06
1.5 W
0x07
1.75 W
0x08
2.0 W
RF600 The transmit power of the reader is set with "distance_limiting".
By default, ANT 1 is used with the preset transmit power.
