Remote Side The device sending data to and receiving data from the VX7 through the serial cable connected to the RS-232
ports on both devices.
Serial Cable: 9000060CABLE
The VX7 serial port supports four types of handshaking via the serial cable: None, standard Xon/Xoff, standard DTR/DSR, and
a form of RTS/CTS.
To use RTS/CTS, the remote side computer must clear the DTR line which sets the VX7 CTS line and allows the VX7 to send
data to the remote side.
And then signals and data travel smoothly between both devices.
