Riello MultiCOM 301 User Manual page 27

BASIC CONFIGURATION
Multicom 301/302 is able to automatically recognize the communication protocol used by
the UPS or the Transfer Switch. To do this , it is necessary to leave the baud rate of the
UPS and/or of the Transfer Switch to the default value (1200 or 9600 bps according to the
type of UPS or Transfer Switch).
If the baud rate of the UPS or of the Transfer Switch is set to different values, the serial
port "UPS SERIAL" of Multicom 301/302 has to be properly configured using the software
MultiSetup.exe (refer to ADVANCED CONFIGURATION)
only for MultiCOM 301 model: For access to the DIP-switches and to the jumpers,
disconnect the power supply connector and the serial cables, take out the four screws on
the bottom of the device and remove the cover.
