13 Serial Port Configuring
The Lecture Recorder x2 can be integrated with control equipment that uses an RS-
232 interface. This RS-232 interface is used to trigger the device to perform various
actions by sending a command over the RS-232 connection, refer to the RS-232
Commands chapter for more information about these commands.
To connect your control equipment to the Lecture Recorder x2, use a standard RS-
232 null-modem cable. Then an RS-232 serial adapter is connected to the RS-232
null-modem cable before inserting it into one of the two USB ports on the Lecture
Recorder x2.
The standard Lecture Recorder x2 package does not include an RS-232 serial adapter
but one can be purchased from Epiphan as an optional accessory.
Flow control is the only configurable item for this feature. This is done by navigating
to the Serial Port section of the Web admin interface.

bytes in a wire. For serial ports this means the ability to
stop and then restart the flow without any loss of bytes.
Specify by what means this control will be performed:
