Ground
The RB-VHDMA8 will interface directly with personal computer serial ports at standard
RS232 signal levels using a straight-through cable. The default format is 19200 baud with 8
data bits, even parity and 1 stop bit. Sonifex SCi software, when installed on a suitable PC,
provides straightforward graphical access to all remote control and configuration options
via both RS232 and Ethernet interfaces. Alternatively, commands may be issued from any
text-based terminal program (e.g. Hyperterminal) or custom software may be developed
for specific requirements.
Ethernet
The Ethernet port is connected using a standard RJ-45 connector on the rear of the panel.
It is a 10/100Mbps link. The unit is shipped with DHCP enabled to allow the unit to be
plug and play if the users local area network has a DHCP server. If one is not available on
the network and the unit cannot retrieve a valid IP address after 45 seconds it will default
to a static address. This static address is set to 192.168.0.100 by default but can be altered
through SCi using the serial port connection. If DHCP is not required then this can also be
disabled through SCi using the serial port connection.
