PC Com Port Connection
SVS routing switchers are shipped from the factory with the baud rate set at 9600 Baud.
The Serial cable should be installed into the “Host” port on the back of the switcher and
Com Port 1 on the PC.
The router’s processor is shipped from the factory with the default settings. Please see
the router’s manual for more information regarding processor dipswitch settings.
SVS routing switchers use only 3 pins of a standard 9 pin D serial cable. In most cases
an “off the shelf” one-to-one cable may be used. Refer to the router’s user’s guide for
correct serial connection on the router host port.
