Host connection ports: IEEE 1394 and USB interface version
RS-232 port
The RS-232 port is used if you want to monitor
the status of your array remotely. An RS-232
cable can connect ACURA 4 to a terminal or PC
equipped with terminal emulation software.
IEEE 1394 ports
The IEEE 1394 ports can be used to connect to
a host machine. Each of the two IEEE ports
supports IEEE 1394 A and B. IEEE 1394 allows
connection of up to 63 devices.
USB port
The USB port can be used to connect to a host
machine. The port supports USB 2.0, which
allows connection of up to 127 devices.
