Jumper field terminating resistor and interface driver
RS485 / RS422
The Ser[LOG] has 6 serial interfaces, some of which can be operated as RS232, RS422 or RS485.
Modbus and a SDI-12 interface are also available.
An RS232 interface with handshake line is only available on COM1.
If SDI-12 sensors are used, they are connected via the separate SDI-12 terminal on the Ser[LOG]. The
COM5 interface is occupied by SDI-12 and the COM5 connection is deactivated.
If the Ser[LOG] is extended with one or more AnDiMod modules, the connection is made via the sepa-
rate 4-pin terminal on the bottom of the housing. The AnDiMod modules occupy the COM6 interface
and the COM6 connection is deactivated.
Since the Ser[LOG]Plus already has an integrated AnDiMod module, COM6 is not available from the
outset.
COM2 to COM6 can be switched from RS485 (factory setting) to RS422 via jumper.
Please note that the configuration of the used interfaces must also be done on the software side
with the Ser[LOG] Commander!
Factory setting:
COM1:
RS232 or RS422*; no terminating resistors
COM2:
RS232 or RS485*; no terminating resistors
COM3:
RS232 or RS485*; no terminating resistors
COM4:
RS232 or RS485*; no terminating resistors
COM5:
RS485*; no terminating resistors
COM6:
RS485*; no terminating resistors
*configurable via software
