RAS-24
USB Interfaces
The RAS-24 comes with a
RS-232 serial port interface as standard equipment and offers adequate
data transfer speeds for 12-channel or 24-channel RAS-24 systems. For
systems with two or more RAS-24s, either the USB-100 or USB-200 must be
used. The USB-100 allows off-end shooting and has an external trigger input
while the USB-200 provides split-spread shooting, external trigger input, and
remote radio controlled trigger input/outputs. The USB-100/200
