J-E-B
System key
Defines the bus system of the MRL-7. Thus, different conceptual bus systems can be separated. Bus
systems may interfere with each other if the remote radio coverage of two measurement systems
overlap.

Output protocol (OP)
The following serial output protocols can be selected. See Section
for a detailed description.
Setting
Description
Sommer (default)
Sommer protocol; data values are returned with an index starting at 1
standard
Standard protocol; data values are returned without an index
J-E-D
OP, measurement output
Specifies the timing of the serial data output.
Setting
Description
just per command
(default)
Data output is requested by commands via the RS-485 or SDI-12 interface.
measured automatic
Data output is performed automatically in the primary measurement inter-
val.
storage automatic
Data output is performed in the main storage interval.
J-E-E
OP, wake-up sequence
Serial data can be transmitted to a recording device automatically without a request. However, many
devices demand a wake-up sequence before they can receive and process data. The MRL-7 has the
option to send a sync sequence and a prefix before data are transmitted (see Section
). The
following options are available:
Parameter
Description
off
No wake-up sequence
sync
The sync sequence
UU~?~?
is sent before the output string.
prefix (default)
A blank with a time delay is sent before the output string.
prefix & sync
A blank with a time delay and the sync sequence
UU~?~?
is sent before the
output string.
J-E-F
OP, prefix holdback
The time delay between the prefix and the data string.
