Pipe-Through Mode 1:
Enable or disable the "pipe-through" of the adapter. If enabled, the RS-232 protocol of the UPS
will be transmitted to the COM2 of the adapter, so now you can connect any other RS-232
software to the adapter to make use of the RS-232 UPS protocol – parallel to the adapter. This
makes the use of multiplexer hardware is no longer necessary. 2 serial interfaces on your UPS
which are working parallel are utilized now. Reminder: If you have enabled this function, you
can no longer configure the adapter via the serial cable, you must changed the settings via
HTTP. As communication cable between CS121 and your application you have to use the
original CS121 configuration cable.
Pipe-Through Mode 2:
Analog to Pipe-through mode 1, the UPS data is piped through to COM2 but not directly. In
order to accelerate the internal processes of the adapter, the UPS data is accumulated into
memory before being made available to COM2. Consequently, Pipe-through mode 2 also does
not provide for the relaying of signals to the UPS through COM2 either. (See also section
"Network & Security Settings")

MODBUS/SPI3
The selection of MODBUS/SPI3 in the drop down menu of the COM2 settings enables the
CS121 MODBUS/SPI3-Profibus function. The default CS121 device types communicating
MODBUS via RS232. The special CS121 device types LM and SCM communicating RS485
via the COM2. You can detect by means of the CS121 serial number 0124-..., if you got a
CS121 with RS485 interface. The CS121_SPI3 Profibus and LONBUS converters will be
connected to the COM2 with RS232 port and as configuration use MODBUS/SPI3.Please take
a look into chapter 6.7 for further information.
TEMPMAN & SENSORMANAGER I & II:
The TEMPMAN and SENSORMANAGER are extensions to the CS121 that connect to COM2
of the adapter. The newer of the two products is the SensorManager. These devices are
simply plugged into the CS121 for setup and the only mandatory change on the adapter to
enable this functioning is to set the COM2 Settings to either TEMPMAN or SENSORMAN. The
configuration is easily achieved via the HTML page of the CS121 web server. Please note the
drop-down menu and entry fields on the page. (see screenshot above) For in-depth
SENSORMANAGER settings see following up chapter.
