5.1.11 Displaying the number of the current memory
Example 1
Input
Output
(example)
Displaying the number of the memory
?SM
+ENTER
Memory: 00004 S
The displayed
S
in the output indicates that the current memory has been selected via software. If the memory has been selected
by hardware, an
H
will be displayed.
5.1.12 Selecting the memory which has been set via hardware
The memory can be selected by connecting the inputs SEL0...SEL 4 (pins 12...16) to DIP switches or to the outputs of a micro-
controller (see chapter
3.2 Memory selection at the user interface
).
If the inputs SEL0 ... SEL4 (pins 12 ... 16) are not connected or connected to +5 V, the memory number will be set to 31. If the
inputs are connected to ground, the memory number will be set to 0.

5.1.13 Displaying the analogue measurement signal RSSI (receive level)
Example 1
Input
Output
(example)
Calling up the RSSI value
A
0
+ENTER
A0
RSSI = 00612
To determine the receive level in dBm proceed as follows:
1.
Calculating the RSSI voltage in Volt
RSSI_voltage =
* RSSI_value
5 V
1023
2.
You can determine the receive level by using the figure
11-8: RSSI response via receive level and temperature
.
