Figure 39: HTTP - COM2 Mode overview
• Configuration Mode:
This sets the normal configuration mode for using the provided cable (CS121-TEMP
configuration cable).
Note: Unless DIP-switch 1 is OFF the COM2 port is always running in
configuration mode.
• 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”)
