Display The two-line LCD display is activated when the rotary push button is oper-
ated. After one minute of idle time, the display switches off automatically.
Mini USB ser-
vice interface
The mini USB port is used solely to configure and verify the device. This
connection is not suitable for permanently connecting the unit to a PC. (Var-
ious PCs inadvertently force a reboot of the device when they switch to or
from the power saving mode. In this case, an averaging block is lost.)
USB host
The USB host port is for plugging-in a USB memory stick or a Bluetooth
adapter. The Ser[LOG] delivers a maximum of 200 mA via USB. Consumers
with higher power consumption are not supported.
Ethernet The network connection of Ser[LOG] supports 10 Mbit / s / 100 Mbit / s. The
device does not support DHCP server but requires a fixed IP address.
COM inter-
faces
The Ser[LOG] has 6 serial ports, which can be partially operated as RS232,
RS422 or RS485. Furthermore, Modbus and SDI-12 interfaces are available.
When SDI-12 sensors used, the connection runs via the separate SDI-12
terminal on Ser[LOG]. In this case the SDI-12 unit occupies COM5 interface
and the COM5 port is disabled.
If the Ser[LOG] is extended with one or more AnDiMod modules, the con-
nection is made via the separate terminal of 4 found on the bottom of the
housing. In this case the AnDiMod modules occupy the COM6 interface and
the COM6 port is disabled.
The COM1 to COM4 may be configured with the Ser[LOG] -Commander to
RS232. An RS232 interface with handshake line is only available on the
COM1.
COM2 to COM6 can be switched via jumper RS485 (default) to RS422. The
COM1 is not switchable to RS485.
The interfaces can be switched on with the Ser[LOG] Commander and off.
SDI-12 inter-
face
The "SDI-12" port has 3 terminals. The communication signal (+) is applied
to the terminal "IO", at terminal "GND", the mass is connected. If the con-
nection cable of the SDI-12 bus carries the bus voltage, it can be parked on
the terminal"(V)". The terminal (V) is not connected to the device’s electron-
ics by the factory (dead set). The Ser[LOG] does not supply the SDI-12 bus
in the standard version with power. The supply of the SDI-12 bus must take
place separately.
Status Inputs The two status inputs "DA" and "DB" can be used for registration of states
(switch ON / OFF).
