VEGA VEGACONNECT 3 - Manual (Page 10)

4 Connection
4.1 Connection to PC/Modem
For connection of VEGACONNECT 3 to a PC or a modem, an
RS
232 interface is absolutely necessary. If your PC has no
RS 232 interface, you can use an USB-RS232 adapter (order
number 2.26900). The voltage supply of VEGACONNECT 3 is
carried out via the control cables of the RS232 interface. If
these do not deliver suffiencient power, an additional power
supply unit can be used (see chapter "Configuration - Power
supply").
VEGACONNECT 3 can be connected with the 9-pole Sub-D
plug directly to the RS232 interface of any PC.
